A recent update on the fixation techniques for femoral neck fractures: A narrative review

Femoral neck fractures present significant challenges in orthopedic surgery, particularly due to technical difficulties and a high complication rate. Surgical intervention is generally recommended, with osteosynthesis and arthroplasty being the main treatment options. Osteosynthesis techniques, including dynamic hip screw (DHS), multiple cannulated screws (MCS), and the femoral neck system (FNS), aim to achieve stable fixation and facilitate fracture healing. Factors influencing the choice of osteosynthesis include fracture displacement, bone quality, patient age, and the presence of posterior tilt. While DHS offers high stability, MCS is preferred in stable type fractures with minimal invasive procedures. FNS, a newer technique, combines the advantages of DHS and MCS, providing strong fixation with minimal soft tissue damage. Considering the comprehensive findings of biomechanical and clinical studies to date, when performing osteosynthesis for unstable femoral neck fractures, caution should be exercised with MCS as it may have slightly inadequate fixation strength compared to DHS and FNS. FNS, being the newest technique, demonstrates superior fixation strength comparable to DHS and is as minimally invasive as MCS. However, it is essential to remember that long-term follow-up results are lacking for FNS.

Vertebral Endplate Changes: Insights Into Its Natural Course and Clinical Implications in Low Back Pain

Abstract This study presents the literature review on vertebral endplate (EP) changes, which are frequently observed in patients with chronic low back pain (LBP). The disc, EP, and bone marrow region of the spine form a single anatomical and functional interdependent unit; isolated degeneration of any one structure is rare. The cartilaginous EP supported by a bony EP is responsible for anatomical integrity and controls diffusion, the only source of nutrition to the disc. A break in the EP establishes disc-bone marrow contact leading to possible severe autoimmune inflammation and also neovascularization and destruction of the disc. Conversely, degeneration, herniation, or infection of the disc will end in the destruction of both EPs as well as involve the subchondral bone. It is then logical that this region must be considered together as a whole. To consider any one of them in isolation can lead to the error of overlooking changes in the other structures of the disc EP bone marrow complex. Modic changes are discussed extensively in the literature from various angles of being a separate clinical phenotype, having a controversial etiology with the possibility of subclinical infection and treatment with antibiotics, having poor outcomes, and having higher complication rates after surgery. This review article highlights our understanding of vertebral EP changes and progression from Modic classification to disc EP bone marrow complex classification with more clearer depiction of its natural course and clinical implication in LBP.

Treatment options for patients with pilonidal sinus disease: PITSTOP, a mixed-methods evaluation.

There is no consensus on optimal management of pilonidal disease. Surgical practice is varied, and existing literature is mainly single-centre cohort studies of varied disease severity, interventions and outcome assessments. A prospective cohort study to determine: • disease severity and intervention relationship • most valued outcomes and treatment preference by patients • recommendations for policy and future research. Observational cohort study with nested mixed-methods case study. Discrete choice experiment. Clinician survey. Three-stage Delphi survey for patients and clinicians. Inter-rater reliability of classification system. Thirty-one National Health Service trusts. Patients aged > 16 years referred for elective surgical treatment of pilonidal disease. Surgery. Pain postoperative days 1 and 7, time to healing and return to normal activities, complications, recurrence. Outcomes compared between major and minor procedures using regression modelling, propensity score-based approaches and augmented inverse probability weighting to account for measured potential confounding features. Clinician survey: There was significant heterogeneity in surgeon practice preference. Limited training opportunities may impede efforts to improve practice. Cohort study: Over half of patients (60%; N = 667) had a major procedure. For these procedures, pain was greater on day 1 and day 7 (mean difference day 1 pain 1.58 points, 95% confidence interval 1.14 to 2.01 points, n = 536; mean difference day 7 pain 1.53 points, 95% confidence interval 1.12 to 1.95 points, n = 512). There were higher complication rates (adjusted risk difference 17.5%, 95% confidence interval 9.1 to 25.9%, n = 579), lower recurrence (adjusted risk difference -10.1%, 95% confidence interval -18.1 to -2.1%, n = 575), and longer time to healing (>34 days estimated difference) and time to return to normal activities (difference 25.9 days, 95% confidence interval 18.4 to 33.4 days). Mixed-methods analysis: Patient decision-making was influenced by prior experience of disease and anticipated recovery time. The burden involved in wound care and the gap between expected and actual time for recovery were the principal reasons given for decision regret. Discrete choice experiment: The strongest predictors of patient treatment choice were risk of infection/persistence (attribute importance 70%), and shorter recovery time (attribute importance 30%). Patients were willing to trade off these attributes. Those aged over 30 years had a higher risk tolerance (22.35-34.67%) for treatment failure if they could experience rapid recovery. There was no strong evidence that younger patients were willing to accept higher risk of treatment failure in exchange for a faster recovery. Patients were uniform in rejecting excision-and-leave-open because of the protracted nursing care it entailed. Wysocki classification analysis: There was acceptable inter-rater agreement (κ = 0.52, 95% confidence interval 0.42 to 0.61). Consensus exercise: Five research and practice priorities were identified. The top research priority was that a comparative trial should broadly group interventions. The top practice priority was that any interventions should be less disruptive than the disease itself. Incomplete recruitment and follow-up data were an issue, particularly given the multiple interventions. Assumptions were made regarding risk adjustment. Results suggest the burden of pilonidal surgery is greater than reported previously. This can be mitigated with better selection of intervention according to disease type and patient desired goals. Results indicate a framework for future higher-quality trials that stratify disease and utilise broad groupings of common interventions with development of a patient-centred core outcome set.

Efficacy and safety of the subcutaneous implantable cardioverter-defibrillator in patients with and without obesity: A meta-analysis

BackgroundThe subcutaneous implantable cardioverter-defibrillator (S-ICD) has emerged as an alternative to transvenous systems for prevention of sudden cardiac death. However, concerns have been raised regarding its efficacy and safety in obese individuals. ObjectiveThe purpose of this study was to perform a meta-analysis to evaluate the efficacy and safety of the S-ICD in patients with obesity by assessing the relationship between body mass index (BMI) and clinical outcomes. MethodsA comprehensive search of multiple databases was conducted for English-language peer-reviewed studies reporting clinical outcomes in S-ICD recipients with (BMI ≥30 kg/m2) and without obesity (BMI <30 kg/m2). Data on preimplantation screening failure, defibrillation testing, complications, appropriate and inappropriate shocks, and survival were analyzed using standard, random-effects, meta-analytical techniques. ResultsTwenty-nine studies involving 20,486 patients were included. There was no statistically significant difference in mean BMI values of patients with failed or successful preimplantation screening (mean difference –0.60 kg/m2; 95% confidence interval [CI] –2.06 to 0.86). Obesity was associated with higher rates of failed defibrillation testing at ≤65 J (odds ratio [OR] 2.16; 95% CI 1.39–3.35), and malpositioning/suboptimal positioning occurred more frequently in obese compared to nonobese patients (OR 3.37; 95% CI 1.76–6.44). Increased BMI as a continuous variable (per increase in 1 kg/m2 BMI) was associated with elevated defibrillation thresholds (OR 1.05; 95% CI 1.03–1.08); higher risk of complications (hazard ratio [HR] 1.04; 95% CI 1.02–1.05); a trend toward an increased number of appropriate shocks (HR 1.02; 95% CI 1.00–1.04); and no significant increase in the risk of inappropriate shocks (HR 1.01; 95% CI 0.99–1.03). ConclusionThis meta-analysis underscores the importance of considering obesity in S-ICD implantation decisions. Although S-ICD remains effective in obese patients, attention to potential technical challenges and higher complication rates is warranted.

Analysis of Calcaneal Avulsion Fractures Treated Surgically and Nonsurgically: A Retrospective Multicenter Study.

Calcaneal avulsion fractures (CAvFs) at the Achilles tendon insertion are among the more challenging fractures to treat. Although rare, they often require reoperation. The optimal treatment, including nonsurgical procedures and better implants for surgical procedures in the treatment of CAvFs, remains to be established. Therefore, our study aimed to (1) perform a descriptive evaluation of CAvFs, including cases managed nonsurgically, and (2) assess surgical procedures, including the incidence of complications and reoperation for surgically treated CAvFs. In this multicenter retrospective study, we collected data of patients with CAvFs treated at 9 hospitals from 2012 to 2022. We performed a descriptive study of CAvFs and compared postoperative complications and reoperation rates for multiple surgical techniques and implants. The size of the bone fragments was quantified. The data of 70 patients with CAvFs were analyzed; 20 patients were treated nonsurgically, and 50 were treated surgically. The mean age of patients was 68.5 years; 67% of the patients were female. Nineteen percent of the patients had diabetes, and 19% had osteoporosis. The incidence of postoperative complications was 30%, with infection in 14%, necrosis in 26%, and loss of reduction in 18%. The reoperation rate was 22%. Surgical techniques with use of cannulated cancellous screws were performed in 80% of the surgical cases. Cannulated cancellous screw (CCS) fixation alone resulted in a reoperation rate of 35%, whereas additional augmentation, including washers with CCS fixation, resulted in a reoperation rate of 10%. CCS fixation was successfully performed, although suture anchors were used in some cases with smaller fragments. CAvFs occurred more frequently in older women and had a high rate of postoperative complications. A combination of CCS with augmentation was more effective at reducing postoperative complications than CCS fixation alone, even when the bone fragment size was small. Therapeutic Level III.

Comparison of early and late aseptic baseplate failure in primary reverse shoulder arthroplasty with and without structural glenoid autograft

Early reverse total shoulder arthroplasty (RTSA) designs demonstrated high glenoid baseplate complication and revision rates. While contemporary designs have reduced the incidence of glenoid baseplate failures, there are reports of elevated failure risks in RTSA with glenoid bone grafting within the first 2 years. This study aims to evaluate the incidence and etiology of aseptic glenoid baseplate failure with a contemporary central screw baseplate. The null hypothesis is that majority of the baseplate failure occurs within the first 2 years and use of glenoid bone grafting does not lead to higher risk of baseplate failure. In 2014 - 2019, 753 consecutive patients who underwent primary RSA using the same inlay press-fit humeral stem and monoblock central screw baseplate were retrospectively reviewed. Fracture and septic arthropathy cases were excluded. All patients underwent preoperative radiographic and computed tomography evaluation. If there was significant glenoid erosion (Walch A2, B2, B3, C1, C2, E2, E3, and/or E4 variants), patient-specific structural glenoid bone grafting was performed. All patients underwent standardized radiographic follow-up and failure was strictly defined as any hardware breakage and/or shift in glenoid baseplate position. Failures were defined as "early" if occurring within 2 years and "late" if occurring greater than 2 years after surgery. Comparative analysis was performed to evaluate demographics, glenoid graft use, and graft union rates between the cohorts. There were 23 patients with baseplate failures (23/753, 3.0%) at mean of 23 months. Twenty-two failures (96%) occurred in patients who received structural glenoid bone grafting. Only 1 failure (0.2%) occurred when bone grafting was not indicated (p<0.001). The most common failure pattern was associated with B2 glenoid (16/23, 70%). There were 5 (22%) early failures and 18 (78%) late failures. There were no differences in any patient demographic characteristics between cohorts. All 5 early failures had graft nonunion and 4/5 occurred without trauma. In the 18 late failures , 9/18 (50%) occurred without trauma (p=0.135). Seventeen of these patients had glenoid grafting, of which 9/17 (53%) had graft nonunion. Contemporary RTSA glenoid baseplate designs have an acceptably low incidence of failure. However, the addition of structural bone graft to correct glenoid wear leads to higher aseptic baseplate failure rate. The majority of these patients suffer failure after the 2-year postoperative mark, highlighting the necessity of longer follow-up. Further analysis is necessary to quantify glenoid characteristics (severity of glenoid erosion, critical size of graft) associated with failure.

Above-knee amputation shows higher complication and mortality rates in line with lower functional outcome compared to knee arthrodesis in severe periprosthetic joint infection

AimsIn cases of severe periprosthetic joint infection (PJI) of the knee, salvage procedures such as knee arthrodesis (KA) or above-knee amputation (AKA) must be considered. As both treatments result in limitations in quality of life (QoL), we aimed to compare outcomes and factors influencing complication rates, mortality, and mobility.MethodsPatients with PJI of the knee and subsequent KA or AKA between June 2011 and May 2021 were included. Demographic data, comorbidities, and patient history were analyzed. Functional outcomes and QoL were prospectively assessed in both groups with additional treatment-specific scores after AKA. Outcomes, complications, and mortality were evaluated.ResultsA total of 98 patients were included, 52 treated with arthrodesis and 47 with AKA. The mean number of revision surgeries between primary arthroplasty and arthrodesis or AKA was 7.85 (SD 5.39). Mean follow-up was 77.7 months (SD 30.9), with a minimum follow-up of two years. Complications requiring further revision surgery occurred in 11.5% of patients after arthrodesis and in 37.0% of AKA patients. Positive intraoperative tissue cultures obtained during AKA was significantly associated with the risk of further surgical revision. Two-year mortality rate of arthrodesis was significantly lower compared to AKA (3.8% vs 28.3%), with age as an independent risk factor in the AKA group. Functional outcomes and QoL were better after arthrodesis compared to AKA. Neuropathic pain was reported by 19 patients after AKA, and only 45.7% of patients were fitted or were intended to be fitted with a prosthesis. One-year infection-free survival after arthrodesis was 88.5%, compared to 78.5% after AKA.ConclusionAbove-knee amputation in PJI results in high complication and mortality rates and poorer functional outcome compared to arthrodesis. Mortality rates after AKA depend on patient age and mobility, with most patients not able to be fitted with a prosthesis. Therefore, arthrodesis should be preferred whenever possible if salvage procedures are indicated.Cite this article: Bone Joint J 2024;106-B(7):669–679.

Optimizing outpatient neurosurgery: evaluating ambulatory surgery and same-day discharge following intracranial tumor surgery and endoscopic third ventriculostomy.

Outpatient surgery and same-day discharge are developing fields that align with the evolving needs of modern healthcare, presenting a notable advantage by reducing patient susceptibility to nosocomial infections, thromboembolic complications, and medical errors. When paired with enhanced recovery after surgery protocols, they hold promise in safely transitioning certain patients undergoing cranial surgery to outpatient care. This study aimed to evaluate discharge on the same day of surgery after intracranial tumor resection and endoscopic third ventriculostomy (ETV) and to investigate potential associations with anesthesia methods, complications, and readmission rates. A retrospective analysis of patients scheduled for planned discharge on the same day of surgery between August 2020 and October 2023 was conducted. Data included patient demographic characteristics, preoperative clinical deficits, diagnosis, findings on preoperative and postoperative MRI, lesion characteristics, complications, and readmission rates. A total of 202 patients were included in the study. The mean age was 56.8 years and 117 (57.9%) patients were female. Patients were admitted the evening before surgery to obtain preoperative clearance and undergo MRI. The most common diagnoses were metastasis (23.3%), meningioma (20.8%), glioblastoma (12.4%), and low-grade glioma (10.4%). Craniotomy (46.5%), stereotactic needle biopsy (35.1), and ETV (6.9%) were the most common procedures performed. Thirteen (6.4%) patients underwent awake craniotomy, and 189 (93.6%) surgical procedures were conducted under general anesthesia. Complications occurred in 1.5% of patients, with no permanent complications observed during a mean follow-up of 9.3 months. In total, 179 (88.6%) patients were successfully discharged on the same day of surgery. The median length of hospitalization was 26.8 hours, with the median length of postoperative stay being 7 hours. Twenty-three (11.4%) patients were deemed ineligible for discharge on postoperative day 0 and instead discharged on postoperative day 1. The reasons for these delays included further clinical monitoring (n = 12), social factors (n = 4), and patient preference (n = 7). Age was positively correlated with length of hospitalization (p = 0.006). In total, 6.4% of patients were readmitted within 1-30 days after discharge, with 2.5% readmitted to the department of neurosurgery. This study demonstrates the safety and feasibility of discharge on the same day of surgery, with a high success rate and low complication rates. Early discharge did not increase morbidity or readmission rates. Implementation of clear discharge protocols and thorough patient education are crucial for successful same-day discharge programs in neurosurgery.

Clinical features and prediction of long-term survival after surgery for perihilar cholangiocarcinoma.

The treatment of perihilar Cholangiocarcinoma (pCCA) poses specific challenges not only due to its high perioperative complication rates but also due its dismal long-term prognosis with only a few long-term survivors (LTS) among the patients. Therefore, in this analysis characteristics and predictors of LTS in pCCA patients are investigated. In this single center analysis, patients undergoing curative-intent liver resection for pCCA between 2010 and 2022 were categorized into long-term and short-term survivors (STS) excluding perioperative mortality. Binary logistic regression was used to determine key differences between the groups and to develop a prognostic composite variable. This composite variable was subsequently tested in the whole cohort of surgically treated pCCA patients using Cox Regression analysis for cancer-specific survival (CSS). Within a cohort of 209 individuals, 27 patients were identified as LTS (median CSS = 125 months) and 55 patients as STS (median CSS = 16 months). Multivariable analysis identified preoperative portal vein infiltration (OR = 5.85, p = 0.018) and intraoperative packed red blood cell (PRBC) transfusions (OR = 10.29, p = 0.002) as key differences between the groups. A prognostic composite variable based on these two features was created and transferred into a Cox regression model of the whole cohort. Here, the composite variable (HR = 0.35, p<0.001), lymph node metastases (HR = 2.15, p = 0.001) and postoperative complications (HR = 3.06, p<0.001) were identified as independent predictors of CSS. Long-term survival after surgery for pCCA is possible and is strongly negatively associated with preoperative portal vein infiltration and intraoperative PRBC transfusion. As these variables are part of preoperative staging or can be modulated by intraoperative technique, the proposed prognostic composite variable can easily be transferred into clinical management to predict the oncological outcome of patients undergoing surgery for pCCA.

Effect of Glenoid Bone Loss and Shoulder Position on Axillary Nerve Anatomy During the Latarjet Procedure.

The Latarjet procedure is increasingly being utilized for the treatment of glenoid bone loss and has a relatively high neurological complication rate. Understanding the position-dependent anatomy of the axillary nerve (AN) is crucial to preventing injuries. To quantify the effects of changes in the shoulder position and degree of glenoid bone loss during the Latarjet procedure on the position of the AN. Controlled laboratory study. A total of 10 cadaveric shoulders were dissected, leaving the tendons of the rotator cuff and deltoid for muscle loading. The 3-dimensional position of the AN was quantified relative to the inferior glenoid under 3 conditions: (1) intact shoulder, (2) Latarjet procedure with 15% bone loss, and (3) Latarjet procedure with 30% bone loss. Measurements were obtained at 0°, 30°, and 60° of glenohumeral abduction (equivalent to 0°, 45°, and 90° of shoulder abduction) and at 0°, 45°, and 90° of humeral external rotation (ER). Abduction of the shoulder to 60° resulted in a posterior (9.5 ± 1.1 mm; P < .001), superior (3.0 ± 1.2 mm; P = .013), and lateral (19.1 ± 2.3 mm; P < .001) shift of the AN, and ER to 90° resulted in anterior translation (10.0 ± 1.2 mm; P < .001). Overall, ER increased the minimum AN-glenoid distance at 30° of abduction (14.9 ± 1.3 mm [0° of ER] vs 17.3 ± 1.5 mm [90° of ER]; P = .045). The Latarjet procedure with both 15 and 30% glenoid bone loss resulted in a superior and medial shift of the AN relative to the intact state. A decreased minimum AN-glenoid distance was seen after the Latarjet procedure with 30% bone loss at 60° abduction and 90° ER (17.7 ± 1.6 mm [intact] vs 13.9 ± 1.6 mm [30% bone loss]; P = .007), but no significant differences were seen after the Latarjet procedure with 15% bone loss. Abduction of the shoulder induced a superior, lateral, and posterior shift of the AN, and ER caused anterior translation. Interestingly, the Latarjet procedure, when performed on shoulders with extensive glenoid bone loss, significantly reduced the minimum AN-glenoid distance during shoulder abduction and ER. These novel findings imply that patients with substantial glenoid bone loss may be at a higher risk of AN injuries during critical portions of the procedure. Consequently, it is imperative that surgeons account for alterations in nerve anatomy during revision procedures. This study attempts to improve understanding of the position-dependent effect of shoulder position and glenoid bone loss after the Latarjet procedure on AN anatomy. Improved knowledge of AN anatomy is crucial to preventing potentially devastating AN injuries during the Latarjet procedure.

Comparative Outcomes and Failure Rates of Total Femur Replacement in Oncologic and Nononcologic Indications: A Systematic Review and Meta-analysis.

Total femur replacement (TFR) has become increasingly significant as a salvage procedure for both oncologic reconstruction and complex nononcologic conditions such as revision arthroplasty. Despite its effectiveness in limb salvage, TFR is associated with high complication and failure rates, which vary depending on the underlying indication. This systematic review and meta-analysis adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of MEDLINE, EMBASE, Web of Science, and Cumulative Index to Nursing and Allied Health Literature databases was conducted, focusing on studies that reported outcomes of TFR in oncologic and nononcologic cases. Primary outcomes included failure mode and rates according to the Henderson classification, functional outcomes scores, and mobility status. Data were analyzed using random-effects models and generalized linear mixed models. A total of 35 studies involving 1,002 patients were included. The majority of TFRs were performed for oncologic reasons (63.7%). The mean Musculoskeletal Tumor Society (MSTS) score was 66%, with a limb salvage rate of 89%. The meta-analysis revealed a combined failure rate of 34%. For type 4 failures (infection), nononcologic patients exhibited a significantly higher rate at 18% (95% confidence interval [CI], 12%-26%, I2 = 46%, p < 0.01) compared with 8% in oncologic patients (95% CI, 6%-12%, I2 = 0%). Regarding combined types 1 to 4 failures, oncologic patients had a rate of 20% (95% CI, 25%-52%, I2 = 60%), whereas nononcologic patients faced a higher rate of 37% (95% CI, 12%-26%, I2 = 63%) (p < 0.05), indicating a significant difference. There were no significant differences in the MSTS score. In addition, there were no notable differences when comparing failure modes 1, 2, and 3 independently. Mobility analysis showed that approximately 70% of patients required walking aids after surgery. TFR offers a valuable limb salvage option in both oncologic and nononcologic scenarios, despite its high failure rates. Although functional outcomes were similar between groups, the higher failure rate in nononcologic cases and the poor overall quality of evidence warrant further comprehensive assessments into predictors of outcomes to optimize results.

Revising Failed Reverse Total Shoulder Arthroplasty: Comprehensive Techniques for Precise Explantation of Well-Fixed Implants.

With the increased utilization of reverse total shoulder arthroplasty (RTSA), there has been a corresponding increase in the incidence of and demand for revision RTSA3. In cases in which the patient has undergone multiple previous surgeries and presents with well-fixed shoulder implants, even the most experienced shoulder surgeon can be overwhelmed and frustrated. Having a simple and reproducible treatment algorithm to plan and execute a successful revision surgery will ease the anxiety of a revision operation and avoid future additional revisions. The extraction techniques described here strive to preserve the humeral and glenoid anatomy, hopefully facilitating the reimplantation steps to follow. The main principles of implant removal include several consistent, simple steps. In order to revise a well-fixed humeral implant, (1) identify the old implants; (2) create a preoperative plan that systematically evaluates the glenoid and humeral deficiencies; (3) prepare consistent surgical tools, such as an oscillating saw, osteotomes, and/or a tamp; (4) follow the deltoid; (5) dissect the soft tissue with a sponge; (6) dissect the bone with use of an osteotome; and (7) remove the humeral stem in rotation. In cases in which there is also a well-fixed glenoid implant, the surgical procedure will require additional steps, including (8) exposure of the anteroinferior glenoid, (9) disengagement of the glenosphere, and (10) removal of the glenoid baseplate in rotation. Alternatives to revision RTSA include nonoperative treatment, implant retention with conversion of modular components, extensile revision surgical techniques, and/or mechanical implant removal. With the advent of modular humeral and glenoid components, surgeons may choose to change the implant components instead of removing the entire humeral and glenoid implants; however, repeat complications may occur if the previous implant or implant position was not completely revised. When confronted with a tough humeral explantation, an extensile surgical approach involves creating a cortical window or humeral osteotomy to expose the humeral implant. This approach can compromise the humeral shaft integrity, leading to alternative and less ideal reconstruction implant choices, the use of cerclage wires, and/or the use of a strut graft, all of which may complicate postoperative mobilization. If glenoid implant removal is necessary, the glenosphere is removed first, followed by the underlying baseplate component(s). If the glenosphere is stuck or if screws are cold-welded, the use of a conventional mechanical extraction technique with a burr or diamond saw may be required; however, this may lead to additional metal debris and intraoperative sparks. Revision RTSA can lead to high complication rates, ranging from 12% to 70%2, which will often require additional revision surgeries4. The first steps to all revision RTSA procedures include careful surgical exposure and component explantation. A simplified approach to expose the humerus and glenoid, coupled with a systematic and atraumatic approach to remove the implants without inadvertent injuries, will prevent surgical complications and the need for re-revision. The proposed comprehensive technique hopefully will allow precise removal of the humeral and glenoid implants while also preserving the remnant humerus or glenoid for future reconstruction. Few studies have evaluated postoperative patient outcomes in revision RTSA. Chalmers et al. performed a meta-analysis and found that patients were able to achieve a mean elevation of 106°, a mean American Shoulder and Elbow Surgeons score of 63, and a mean Single Assessment Numeric Evaluation score of 522. Boileau showed very similar outcomes, with a mean elevation of 107° and a mean adjusted Constant score of 621. These outcomes are slightly inferior to those of primary RTSA, but patients remain satisfied with their improvement from their preoperative function. Preoperative preparation will reduce intraoperative reparation. Know the existing implant and the unique features of its design, understand the patient anatomy including bone defects, and anticipate all of the potential tools that may be needed.Know your anatomy. The anteromedial deltoid edge will help you identify the scarred-in humeral shaft.Da Vinci said that simplicity is the ultimate sophistication. Some of the most common surgical tools and instruments can be more effective than custom-designed ones.The implant should be removed in rotation.There are some company-specific explantation instruments that can be very helpful. Give the appropriate ones a try, but be prepared to consider alternative solutions. RTSA = reverse total shoulder arthroplastyCT = computed tomographyFE = forward elevation.

Retropharyngeal and parapharyngeal infections in children: A retrospective analysis

ObjectivesTo describe presentations, management and outcomes of retropharyngeal and parapharyngeal infections in children presenting to a tertiary care pediatric emergency department. MethodsA retrospective chart review of children with deep neck infections such as retropharyngeal or parapharyngeal infection from January 2008 to December 2018 was conducted at a pediatric hospital. ResultsThere were 176 retropharyngeal, 18 parapharyngeal and 6 with both retropharyngeal and parapharyngeal infections treated during the 10-year study period. Males were 60% of the cohort and the mean age was 4.3 (SD: 3.2) years. No significant differences in age or sex ratio or presentations were seen in children with retropharyngeal infections compared with parapharyngeal infections. All received parenteral antibiotics; 42% (84/200) of children underwent surgery and four of them had more than one surgical drainage. Age <12 months and the diagnosis of parapharyngeal infections were associated with significantly higher rates of surgical treatment. Children under 12 months of age were sicker at presentation and had a high complication rate of 23% compared with 1% in the older children (p = 0.002). Seven children had co-existence of Kawasaki disease with deep neck infections. ConclusionsEarly diagnosis of retropharyngeal and parapharyngeal infections especially in infants under a year of age is important as they are more likely to have complications and need surgical management. Most paediatric patients with retropharyngeal and parapharyngeal infections have a phlegmon or very small abscesses and are treated non-operatively with parenteral antibiotics.

A Review of High-Risk Pregnancy Complications in the Resident Clinic

Introduction: A high risk status can develop during a patient’s pregnancy or can be present from conception. These include maternal pre-existing conditions such as hypertension, diabetes, infection such as HIV, and obesity. Fetal complications such as anomaly or multiple gestation also constitute high risk pregnancies. The Corewell Health East Dearborn resident high risk clinic helps to manage these patients’ pregnancies and deliveries. This study aims to analyze the current complications and delivery outcomes of pregnancies from this clinic. Methods: The prenatal care data and pregnancy outcomes from patients in our high-risk resident clinic was collected from Jan 1st 2023 to Jan 1st 2024. The prenatal care data was analyzed for maternal and fetal complications along with delivery outcomes. Results: During the year 2023, 100 patients delivered from the high-risk clinic. Fetal complications were found in 32% of these deliveries. These included 12% twin gestation, 14% growth restriction, 6% fetal anomalies. Maternal complications included 27% with chronic hypertension, 23% with prior cesarean section, 27% with a BMI of 40 or higher, 10% cardiac complications, 4% pre-existing renal complications, 26% with pre-existing diabetes, 3% wtih HIV, and 6% with polysubstance use. The deliveries included 62% cesarean sections and 34% vaginal deliveries. Discussion: The results from our cross-sectional study revealed a high rate of maternal and fetal complications among patients from our high-risk clinic when compared to national averages. There was a high cesarean section rate for these patients. Conclusions: This study allowed us to better understand the patient population that receives care through the resident high-risk clinic. Future studies can explore how to decrease the cesarean section rate.

Characteristics, trends, and management of Penile cancer in the United States: A population-based study

BackgroundPenile cancer (PeCa) is a rare disease. HPV infection, smoking, phimosis, and lichen sclerosus represent well-known associated risk factors. ObjectivesPrimary aim of our study is to evaluate the incidence and risk factors of PeCa and to outline the adopted diagnostic and therapeutic approaches. Secondary aim is to investigate risk factors associated with aggressive disease and to identify the complications arising from its surgical treatment. Materials and MethodsWe conducted a retrospective analysis using the PearlDiver™ Mariner database, from January 1, 2011, to December 31, 2021, identifying all patients diagnosed with PeCa and PeIN, evaluating comorbidities, risk factors, and social and economic conditions. We evaluated the imaging modalities employed for staging as well as the treatment strategies. Finally, we evaluated the most frequent complications associated with inguinal lymphadenectomy (ILND). ResultsDuring the study period, 17,494 patients were diagnosed with PeCa and 5,965 with penile intraepithelial neoplasia (PeIN). US was the most frequently utilized imaging modality, followed by PET and PET/CT. Use of CT and MRI was around 5%. Surgical treatment was the predominant strategy, utilized in 31.3% of PeCa and 22.9% of PeIN. Wide Local Excision/Glansectomy emerged as the most common surgical procedures. MLR analysis identified smoking as a risk factor for metastatic PeCa (OR; 95% CI = 1.49; 1.379–1.609), HPV infections were associated with a 35% decrease in risk (OR; 95% CI = 0.65; 0.562–0.744) (all P < 0.001). Lichen sclerosus and phimosis were associated with a doubled risk of demolitive surgery. Approximately 40% of patients experienced complications associated with ILND. ConclusionDespite advances in PeCa management, there's no significant move toward more conservative treatments. Surgical treatments are still marked by high rates of complications, potentially affect the sexual and psychosocial health of patients. These issues may foster a tendency toward avoidance behaviors, contributing to a delayed clinical presentation and treatment.

Efficacy of Ksharasutra Therapy in the Management of Bhagandara (Fistula-in-ano): A Case Study

Bhagandara, or Fistula-in-Ano as it is termed in modern medical parlance, is a persistent and distressing condition that gives rise to an abnormal connection between the anorectal canal and the perianal skin. While conventional surgical approaches to the condition prove adequately effective, they tend to produce high rates of complications and recurrences. Hence, this study. which sets out to explore the effectiveness of Ksharasutra, an Ayurvedic para-surgical intervention, regarding the management and treatment of Bhagandara. Ksharasutra treatment is performed by inserting a medicated thread, prepared specifically for the purpose, along the fistulous tract, where the thread slowly cuts through the tract and healing it over a period. The patient chosen for inclusion in the case study is a 35-year-old male who displayed the classic characteristic signs of suffering from a low trans-sphincteric fistula on initial presentation, i.e. recurring secretion of blood, pus, and other discharge from a swelling in the perianal region as well as severe pain. The treatment was performed over 8 weeks, with regular weekly changes of the thread and visits to the clinic. Significant improvement was observed, including the complete healing of the fistulous tract, with no complications or relapses noted post-treatment. The study concludes the potential of Ksharasutra treatment as a viable alternative to conventional approaches to the treatment of Bhagandara, as it is not only safer a significantly lower rate of complications and recurrence but also promotes quicker healing and a higher quality of life for patients. The study underscores the need to develop the standardized protocol for treatment and test the long-term effects of Ksharasutra therapy for Fistula-in-Ano on broader sample sizes.

Step-Up versus Open Approach in the Treatment of Acute Necrotizing Pancreatitis: A Case-Matched Analysis of Clinical Outcomes and Long-Term Pancreatic Sufficiency.

Background/Objectives: Acute necrotizing pancreatitis (ANP) with secondary infection of necrotic tissue is associated with a high rate of complications and mortality. The optimal approach is still debatable, but the minimally invasive modality has gained great attention in the last decade as it follows the principle of applying minimal surgical trauma to achieve a satisfying therapeutic objective. We compared clinical outcomes between the step-up approach (SUA) and open necrosectomy (ON) in the treatment of acute necrotizing pancreatitis. Methods: A prospective cohort study over the period of 2011-2021 in a university teaching hospital was performed. Results of 99 consecutive patients with ANP who required surgical/radiological intervention were collected. A case match analysis (2:1) was performed, and the final groups comprised 40 patients in the OA group and 20 patients in the SUA group. Demographic, clinicopathologic, and treatment data were reviewed. Results: Baseline characteristics and disease severity were comparable between the two groups. The patients from the SUA group had a significantly lower morbidity rate and rate of pancreatic insufficiency. Death occurred in 4 of 20 patients (20%) in the SUA group and in 11 of 40 patients (27.5%) in the ON group (risk ratio with the step-up approach, 0.72; 95% confidence interval, 0.26 to 1.99; p = 0.53). Conclusions: A minimally invasive step-up approach provides comparable outcomes to open necrosectomy in the treatment of ANP with infected pancreatic necrosis. While mortality and hospital stay were comparable between the groups, morbidity and pancreatic insufficiency were significantly lower in the SUA group. Further studies on a larger number of patients are required to define the place of SUA in the modern treatment of ANP.

Sarcopenia adversely impacts clinical outcomes in patients undergoing pancreaticoduodenectomy: A systematic review and meta-analysis.

Sarcopenia is a syndrome marked by a gradual and widespread reduction in skeletal muscle mass and strength, as well as a decline in functional ability, which is associated with malnutrition, hormonal changes, chronic inflammation, disturbance of intestinal flora, and exercise quality. Pancreatoduodenectomy is a commonly employed clinical intervention for conditions such as pancreatic head cancer, ampulla of Vater cancer, and cholangiocarcinoma, among others, with a notably high rate of postoperative complications. Sarcopenia is frequent in patients undergoing pancreatoduodenectomy. However, data regarding the effects of sarcopenia in patients undergoing pancreaticoduodenectomy (PD) are both limited and inconsistent. To assess the influence of sarcopenia on outcomes in patients undergoing PD. The PubMed, Cochrane Library, Web of Science, and Embase databases were screened for studies published from the time of database inception to June 2023 that described the effects of sarcopenia on the outcomes and complications of PD. Two researchers independently assessed the quality of the data extracted from the studies that met the inclusion criteria. Meta-analysis using RevMan 5.3.5 and Stata 14.0 software was conducted. Forest and funnel plots were used, respectively, to demonstrate the outcomes of the sarcopenia group vs the non-sarcopenia group after PD and to evaluate potential publication bias. Sixteen studies encompassing 2381 patients were included in the meta-analysis. The patients in the sarcopenia group (n = 833) had higher overall postoperative complication rates [odds ratio (OR) = 3.42, 95% confidence interval (CI): 1.95-5.99, P < 0.0001], higher Clavien-Dindo class ≥ III major complication rates (OR = 1.41, 95%CI: 1.04-1.90, P = 0.03), higher bacteremia rates (OR = 4.46, 95%CI: 1.42-13.98, P = 0.01), higher pneumonia rates (OR = 2.10, 95%CI: 1.34-3.27, P = 0.001), higher pancreatic fistula rates (OR = 1.42, 95%CI: 1.12-1.79, P = 0.003), longer hospital stays (OR = 2.86, 95%CI: 0.44-5.28, P = 0.02), higher mortality rates (OR = 3.17, 95%CI: 1.55-6.50, P = 0.002), and worse overall survival (hazard ratio = 2.81, 95%CI: 1.45-5.45, P = 0.002) than those in the non-sarcopenia group (n = 1548). However, no significant inter-group differences were observed regarding wound infections, urinary tract infections, biliary fistulas, or postoperative digestive bleeding. Sarcopenia is a common comorbidity in patients undergoing PD. Patients with preoperative sarcopenia have increased rates of complications and mortality, in addition to a poorer overall survival rate and longer hospital stays after PD.

Total hip arthroplasty for fractured neck of femur does not restore preoperative hip-specific function, health-related quality of life, or level of fitness

PurposeThe primary aim was to assess whether a total hip arthroplasty (THA) was able to restore health-related quality of life (HRQoL) following an intracapsular hip fracture. The secondary aims were to assess changes in hip-specific function, fitness/frailty, mortality risk, complications and revision risk, and factors independently associated with these.MethodsThis retrospective cohort study included all patients aged ≥ 50 years admitted with a hip fracture from the emergency department at a single centre during a 42-month period. Patient demographics, perioperative variables, complications, revision, and mortality were collected. Patient-reported outcome measures (PROMs) were assessed at final follow-up.ResultsAmong 250 identified patients, 189 (75.6%) were women with a mean age of 70.3 (range 50–94 years). Mean follow-up was 2.3 (SD 1.1) years. The implant and patient survival rates at 2 years were both 95.5% (95% confidence intervals (CI) +/− 2.7). Older age (hazard ratio [HR] 1.22, 95% CI 1.12–1.33, p < 0.001) and male sex (HR 3.33, 95% CI 1.15–10.0, p = 0.026) were independently associated with mortality. There were 19 (7.6%) postoperative complications that included 6 (2.4%) periprosthetic fractures, 5 (2.0%) deep infections, and 8 (3.2%) dislocations, of which 13 underwent revision. Increasing time to theatre (HR 1.02, 95% CI 1.01–1.03, p = 0.017) was independently associated with a postoperative complication. Postoperative PROMs were available for 166 (66.4%) patients. There were significant (p < 0.001) deteriorations in EuroQol-5D (Mean difference [MD] 0.192, 95% CI 0.133–0.252), Oxford hip score (MD 2.5, 95% CI 1.5–3.6), and fitness (Rockwood score MD 0.7, 95% CI 0.5–0.8) relative to preoperative levels of function.ConclusionTHA may be the treatment of choice in a physically active patient with the aim of restoring their HRQoL, hip function, and fitness, but this was not observed. Furthermore, there was a high complication rate which was associated with increasing time to theatre.Level of evidenceIII, retrospective cohort study.

Comorbid background on the waiting list for liver transplantation. Clinical case of liver cirrhosis as a result of chronic viral hepatitis B with a delta agent in combination with cardiac arrhythmia

Hepatitis D virus is a dependent virus that depends on hepatitis B virus for replication and transmission. Chronic hepatitis D virus (HDV) is a severe form of viral hepatitis that can lead to end-stage liver disease and hepatocellular carcinoma. Liver transplantation (LT) is the only treatment option for patients with end-stage liver disease, hepatocellular carcinoma, or fulminant hepatitis caused by HDV coinfection. Also, the presence of a comorbid background is associated with a higher rate of complications, longer hospitalization and worse survival both before and after LT. We present a case of liver cirrhosis as a result of HBV+HDV co-infection in combination with arrhythmia in a patient on the waiting list for LT in the Rostov region.
