Botulinum toxin augmented surgery versus conventional surgery in the management of large-angle concomitant esotropia: A randomized clinical trial.

The surgical management of large-angle concomitant esotropia is challenging with high reoperation rates. This study aims to assess the effectiveness and safety of intraoperative botulinum toxin A (BTA) augmentation compared to surgery alone in large angle concomitant esotropia. This is a prospective randomized interventional study. Patients with large angle concomitant esotropia (≥55 prism diopter [PD]) were randomly allocated to either surgery only (Group I) or BTA augmented surgery (Group II). The surgical effect in PD/mm was calculated and compared between the study groups at all follow up intervals. Treatment was considered successful if the patients had orthotropia ± 10 PD at their final examinations. A total of 23 patients were included in the study, 11 in Group I and 12 in group II. The surgical effect was significantly greater in Group II compared to Group I at all follow up durations. The 1-year surgical effect was 32.5% greater in Group II compared to Group I (5.99 ± 0.69 vs. 4.52 ± 0.91 PD/mm, respectively, P = 0.001). The success rate was greater for Group II compared to Group I (75% vs. 63.64%, respectively), but this difference was not statistically significant (P = 0.901). Botulinum toxin augmented surgery is a good alternative to surgery alone in the treatment of large angle concomitant esotropia. BTA injection exerts a significant augmentation effect on medial rectus muscle recessions.

Significant improvements in clinical outcome measures and patient satisfaction after combined all-arthroscopic meniscal allograft transplantation and autologous chondrocyte implantation: A single-centre longitudinal study.

The optimal treatment approach for the complex pathology of meniscal insufficiency and coexisting full-thickness cartilage defects remains unclear. The purpose of this study was to evaluate the viability, safety, and efficacy of this combined surgical approach at medium-term follow-up. This is a single-centre longitudinal study with blinded outcome assessment. All consecutive patients treated with combined all-arthroscopic meniscal allograft transplantation (MAT) with bone bridge fixation and ACI using chondrospheres at our institution between 2001 and 2021 were eligible for inclusion. Twenty patients with an average follow-up of 72.6 ± 34.4 months were included in the statistical analysis. Clinical outcomes were assessed pre- and postoperatively using the IKDC Subjective Knee Form, Lysholm Score, Tegner Activity Scale, KOOS, and Visual Analog Scale (VAS) for patient satisfaction. Failure and reoperation rates were assessed, and cartilage regeneration tissue was evaluated on postoperative MRI. IKDC scores significantly improved from 52.1 ± 16.9 to 68.5 ± 16.3 (p = 0.003). Lysholm scores improved from 61.5 ± 21.7 to 78.5 ± 12.9 (p = 0.004). Tegner scores improved from 3.5 (1-4) to 4.0 (2-6) (p = 0.014). KOOS scores improved significantly across all subcategories, except 'symptoms', where improvements did not reach statistical significance. VAS for overall patient satisfaction showed improvements but did not reach statistical significance. The combined procedure was successful in 17 patients (85%). Eight patients had to undergo reoperation (40%), comprising mostly small, arthroscopic procedures. Seven reoperations were directly attributable to meniscal allograft transplantation (46.7%). Postoperative Magnetic Resonance Observation of Cartilage Repair Tissue scores were 68.9 ± 16.8 (n = 14). Combined arthroscopic MAT and autologous chondrocyte implantation (ACI) is a viable, safe, and effective treatment approach for younger patients with meniscal insufficiency and coexisting full-thickness cartilage damage, where alternative treatment options are limited. The combined surgical procedure achieved significant improvements in clinical outcome measures and patient satisfaction with acceptable failure and high arthroscopic reoperation rates. MAT is the limiting part of this combined procedure, with most failures and reoperations being attributable to MAT, as opposed to ACI. Level III.

Management of Garden-I and II Femoral Neck Fractures: Perspectives on Primary Arthroplasty.

This review compares internal fixation versus arthroplasty in the treatment of nondisplaced femoral neck fractures (FNFs) calling attention to evolving areas of consensus that influence clinical decision-making. The Garden classification system, typically dichotomized into nondisplaced (types I and II) and displaced (types III and IV) fractures, has been used as a guide for surgical decision-making. Conventionally, treatment of nondisplaced FNF in the elderly has been with internal fixation, and treatment of a displaced FNF has been hemi-, or more recently total hip, arthroplasty. Studies over the last decade have raised concern over the appropriate treatment of nondisplaced FNFs due to high rates of reoperation of nondisplaced FNFs treated with internal fixation. Avascular necrosis (AVN), failure of internal fixation, secondary malunion, and pin/nail penetration through the femoral head have all been observed. Several studies have attributed fixation failure to a degree of femoral neck tilt ≥20°, either posteriorly or anteriorly as seen on the lateral X-ray. Because of these observations of fixation failures, the suggestion has been made that arthroplasty be used when the degree of posterior tilt exceeds a threshold of ≥20° tilt with the expectation of diminishing failure of fixation, decreasing the risk of reoperation and preserving function without increasing mortality rate. Frustrating additional analyses are uncertainties over the mechanisms of failure of internal fixation with ≥20° tilt and the persistently substantial 1-year mortality rate after FNF, which has not been influenced by fixation or replacement type. Due to the lack of consensus regarding the determination of the appropriate surgical intervention for nondisplaced FNFs, an improved algorithm for surgical decision-making for these fractures may prove useful.

Primary Arthrodesis of Non-thumb Metacarpophalangeal Joints of the Hand: Clinical and Patient-Reported Outcomes.

Metacarpophalangeal (MCP) joint arthritis is common secondary to a variety of inflammatory, degenerative, and traumatic causes. Although MCP arthroplasty is more common for the second to fifth digits, primary arthrodesis can be used for high-demand patients with arthritis or unsalvageable fractures of the MCP joint. There has been limited recent studies on the outcomes of these patients. A retrospective review of 38 fingers in 27 patients with primary arthrodesis from 1990 to 2020 was conducted. The major outcomes were complications, reoperations, radiographic union, and time to union. Patient-reported outcomes including the Michigan Hand Outcomes Questionnaire and a questionnaire specific to the operative MCP joint were collected. Rate of radiographic union was 84% including revisions. The average time to union was 3.6 months. Rates of complications, reoperation, and amputation were 26%, 16%, and 7%, respectively. Arthrodesis as part of emergent trauma reconstruction was significantly more likely to result in reoperation (50% vs 7%) and complication (63% vs 17%) than chronic arthritis. Patient-reported outcomes were fair to good with improvement in pain (79%), function (66%), and appearance (40%). Sixty-six percent (66%) of patients were satisfied with their surgery, and 73% would repeat the surgery. Arthrodesis for unsalvageable MCP fractures was associated with higher rates of reoperation and complication than inflammatory or degenerative arthritis. Excluding emergent trauma, MCP fusion was reliable with a reoperation rate of 7% and a modest complication rate of 17%. Patients rated reasonable levels of satisfaction and willingness to repeat the procedure despite complications.

Single-Level Anterolateral and Posterior Interbody Fusion Techniques are Associated With Equivalent Long-Term Lumbar Reoperations.

Retrospective cohort study. This study compares reoperation rates and complications following single-level anterior lumbar interbody fusion (ALIF)/lateral lumbar interbody fusion (LLIF) and transforaminal lumbar interbody fusion (TLIF)/posterior lumbar interbody fusion (PLIF). ALIF, LLIF, TLIF, and PLIF are widely used for degenerative disc disease. Lumbar interbody fusions have high rates of reoperation, primarily related to adjacent segment pathology and pseudarthrosis. The PearlDiver database was queried for patients (2010-2021) who had single-level ALIF/LLIF or TLIF/PLIF with same-day, single-level posterior instrumentation. ALIF/LLIF were combined, and similarly, TLIF/PLIF were combined, given how these operations are indistinguishable from Current Procedural Terminology coding. All patients were followed for ≥2 years and excluded if they had spinal traumas, fractures, infections, or neoplasms before surgery. The two cohorts, ALIF/LLIF and TLIF/PLIF, were matched 1:1 based on age, sex, Elixhauser-comorbidity index, smoking status, and diabetes. The primary outcome was the incidence of all-cause subsequent lumbar operations. Secondary outcomes included 90-day surgical complications. After 1:1 matching, each cohort contained 14,070 patients. All-cause subsequent lumbar operations were nearly identical at five-year follow-up (9.4% ALIF/LLIF vs. 9.5% TLIF/PLIF, P =0.91). Survival analysis using all-cause subsequent lumbar operations as the endpoint showed an equivalent 10-year survival rate of 86.0% (95%CI: 85.2-86.8). Within 90 days, TLIF/PLIF had more infections (1.3% vs. 1.7%, P =0.007) and dural injuries (0.2% vs. 0.4%, P =0.001). There was no difference in wound dehiscence, hardware complications, or medical complications. As utilized in real-world clinical practice, single-level anterolateral versus posterior approaches for interbody fusion have no effect on long-term reoperation rates.

Towards navigation in endoscopic kidney surgery based on preoperative imaging.

Endoscopic renal surgeries have high re-operation rates, particularly for lower volume surgeons. Due to the limited field and depth of view of current endoscopes, mentally mapping preoperative computed tomography (CT) images of patient anatomy to the surgical field is challenging. The inability to completely navigate the intrarenal collecting system leads to missed kidney stones and tumors, subsequently raising recurrence rates. A guidance system is proposed to estimate the endoscope positions within the CT to reduce re-operation rates. A Structure from Motion algorithm is used to reconstruct the kidney collecting system from the endoscope videos. In addition, the kidney collecting system is segmented from CT scans using 3D U-Net to create a 3D model. The two collecting system representations can then be registered to provide information on the relative endoscope position. Correct reconstruction and localization of intrarenal anatomy and endoscope position is demonstrated. Furthermore, a 3D map is created supported by the RGB endoscope images to reduce the burden of mental mapping during surgery. The proposed reconstruction pipeline has been validated for guidance. It can reduce the mental burden for surgeons and is a step towards the long-term goal of reducing re-operation rates in kidney stonesurgery.

Characterizing utilization patterns and reoperation risk factors of interspinous process devices: analysis of a national claims database.

Interspinous process devices (IPDs) were developed as minimally invasive alternatives to open decompression surgery for spinal stenosis. However, given high treatment failure and reoperation rates, there has been minimal adoption by spine surgeons. This study leveraged a national claims database to characterize national IPD usage patterns and postoperative outcomes after IPD implantation. Using the PearlDiver database, we identified all patients who underwent 1- or 2-level IPD implantation between 2010 and 2018. Univariate and multivariable logistic regression was performed to identify predictors of the number of IPD levels implanted and reoperation up to 3 years after the index surgery. Right-censored Kaplan-Meier curves were plotted for duration of reoperation-free survival and compared with log-rank tests. Patients (n = 4865) received 1-level (n = 3246) or 2-level (n = 1619) IPDs. Patients who were older (adjusted odds ratio [aOR] 1.02, 95% confidence interval [CI] 1.01-1.03, P < .001), male (aOR 1.31, 95% CI 116-1.50, P < .001), and obese (aOR 1.19, 95% CI 1.05-1.36, P < .01) were significantly more likely to receive a 2-level IPD than to receive a 1-level IPD. The 3-year reoperation rate was 9.3% of patients when mortality was accounted for during the follow-up period. Older age decreased (aOR 0.97, 95% CI 0.97-0.99, P = .0039) likelihood of reoperation, whereas 1-level IPD (aOR 1.37, 95% CI 1.01-1.89, P = .048), Charlson Comorbidity Index (aOR 1.07, 95% CI 1.01-1.14, P = .018), and performing concomitant open decompression increased the likelihood of reoperation (aOR 1.68, 95% CI 1.35-2.09, P = .0014). Compared with 1-level IPDs, 2-level IPDs were implanted more frequently in older, male, and obese patients. The 3-year reoperation rate was 9.3%. Concomitant open decompression with IPD placement was identified as a significant risk factor for subsequent reoperation and warrants future investigation.

Radiological and Clinical Prognostic Factors of Recurrence of Subacute and Chronic Subdural Hematomas

Objectives. To assess characteristic data of patients hospitalized due to subacute subdural hematomas (SSDHs) and chronic subdural hematomas (CSDHs) and to evaluate radiological findings and establish predictors of hematoma recurrence of SSDHs and CSDHs patient populations. Methods. 149 patients with SSDHs and CSDHs who underwent surgery at Kaunas Clinics Neurosurgery Department from 2020 to 2021 were analyzed. Based on recurrence rate, patients were divided into different subtypes based on computer tomography (CT) imaging. Descriptive analysis, hypothesis testing and correlation matrix were performed using Excel spreadsheet and R programming language with the significance at p-value &lt; 0.05. Results. Out of 149 patients, SSDHs and CSDHs were observed in 89 males (59.6%) and 60 (40.3%) females. Mean of the patients age was 71.1±15 years. Dichotomizing results based on recurrence (cut-off value of 25%), 2 groups were made: 1) low reoperation rate –hypodense sedimented (10%), isodense (21.6%), hypodense (22.2%); 2) high reoperation rate – hypodense bridging (26.7%), hypodense trabecular (27.8%), hypodense with acute bleeding (28.6%), hypodense laminar (30%), isodense with acute bleeding (33.3%). Conclusion. It is concluded that based on 25% reoperation rate high-recurrence and low-recurrence chronic subdural hematomas groups were similar in all terms apart from the hematoma thickness (mm), which leads to a fact that radiological appearance of higher recurrence hematomas should be carefully taken into consideration.

How Often Do Patients Need Retreatment After Surgery for Subdural Hematoma? A Nationwide Readmission Database Analysis

Background The incidence of subdural hematoma is increasing as the average age in the United States rises, with reported high recurrence and reoperation rates. We therefore aimed to have a better understanding of retreatment following surgical evacuation of subdural hematoma in real‐world practice. Methods Data were extracted from the latest available Nationwide Readmissions Database (2016–2019). Adult patients diagnosed with subdural hematoma who had burr‐hole or craniotomy were included in the study. Results Retreatment rates were relatively low in both cohorts, with patients in the burr‐hole cohort having a slightly higher rate of retreatment compared with the craniotomy cohort (8.4% versus 6.6%, P &lt;0.001). The majority (&gt;95%) of retreatments occurred within 90 days of initial treatment, and further follow‐up did not demonstrably increase retreatment on Kaplan–Meier analysis. Retreatment rates remained consistent during the 4‐year study period in both burr‐hole (7.2%–10.4%), and craniotomy cohorts (6.4%–6.8%). Conclusions Analysis of a large national database of unselected patients shows retreatment rates after surgery for subdural hematoma are lower than suggested by prior studies. Almost all retreatments occur within 90 days after initial treatment, which may have implications for length of follow‐up for such patients.

Reoperation rate and risk factors of reoperation for ossification of the posterior longitudinal ligament (OPLL): a systematic review and meta-analysis.

Revision surgery for OPLL is undesirable for both patients and physicians. However, the risk factors for reoperation are not clear. Thus, we sought to review the existing literature and determine the factors associated with higher reoperation rates in patients with OPLL. A search was performed using Pubmed, Embase, Web of Sciences, and Ovid to include studies regarding the risk factors of reoperation for OPLL. RoBANS (Risk of Bias Assessment tool for Nonrandomized Studies) was used for risk of bias analysis. Heterogeneity of studies and publication bias was assessed, and sensitivity analysis was performed. Statistical analysis was performed with a p-value < 0.05 using SPSS software (version 23). Twenty studies with 129 reoperated and 2,793 non-reoperated patients were included. The pooled reoperation rate was 5% (95% CI: 4% to 7). The most common cause of reoperation was residual OPLL or OPLL progression (n = 51, 39.53%). An increased risk of additional surgery was found with pre-operative cervical or thoracic angle(Standardized mean difference = -0.44; 95% CI: -0.69 to -0.19; p = 0.0061), post-operative CSF leak (Odds ratio, OR = 4.97; 95% CI: 2.48 to 9.96; p = 0.0005), and graft and/or hardware failure (OR = 192.09; 95% CI: 6.68 to 5521.69; p = 0.0101). Apart from the factors identified in our study, the association of other variables with the risk of second surgery could not be ruled out, owing to the complexity of the relationship and significant bias in the current literature.

Long-term risk of reoperation after modular hemiarthroplasty

BackgroundIt is unclear whether unipolar (UHA) or bipolar (BHA) hemiarthroplasty should be the preferred treatment of femoral neck fracture (FNF).AimWe investigated the reoperation rate at 13 years post-fracture after BHA and UHA as treatment of FNF, including a subgroup analysis of individuals who survived 5 years or more, and described the reasons for reoperation after BHA and UHA respectively.MethodsIn an observational cohort study on prospectively collected national register data, 16,216 BHA and 22,186 UHA were available for matching. A propensity score for treatment with bipolar HA was estimated using logistic regression. Matching was done using the 1:1 nearest neighbor matching without replacement. Of the 16,216 BHA patients, 12,280 were matched to a UHA control. A subgroup analysis based on the matched sample excluded individuals who died within 5 years and comprised 3,637 individuals with BHA and 3,537 with UHA. Kaplan-Meier survival analysis was used.ResultsIn the Kaplan-Meier analysis, 92% of the BHA group was free from reoperation at 13 years (95% CI 0.91–0.93), compared to 92% in the UHA group (CI 0.89–0.94). BHA was associated with more reoperations until 3 years. Reoperation due to infection was most common after BHA, n = 212 (1.7%) compared to n = 141 (1.1%) after UHA. Dislocation led to reoperation in 192 of the BHA cases (1.6%) and in 157 of the UHA cases (1.3%). Acetabular erosion/pain occurred in 0.1% and 0.4%. Amongst those surviving ≥ 5 years, 93% of the BHA group was free from reoperation (CI 0.92–0.94) at 13 years, 92% after UHA (CI 0.90–0.94). BHA had more reoperations during the 1st year only. The causes for reoperations showed similar rates except for acetabular erosion/pain. Here the BHA group had 2 cases (0.1%), the UHA had 39 (1.1%).ConclusionWith a modular hemiarthroplasty relatively few patients need a reoperation. During the first years, there is a higher reoperation rate after BHA compared to UHA. Thereafter, no differences are seen. In patients who survive ≥ 5 years after the fracture there are more reoperations due to acetabular erosion after UHA, but crude numbers are extremely low, and the total reoperation rate is not affected.

Predicting wound complications following lower extremity revascularization

ObjectiveThe aim of this study was to create a simple risk score to identify factors associated with wound complications after infrainguinal revascularization. MethodsThe Veterans Affairs Surgical Quality Improvement Program national data set was queried from 2005 to 2021 to identify 22,114 patients undergoing elective open revascularization for peripheral arterial disease (claudication, rest pain, tissue loss) or peripheral aneurysm. Emergency and trauma cases were excluded. The data set was divided into a two-thirds derivation set and one-third validation set to create a risk prediction model. The primary end point was wound complication (wound dehiscence, superficial/deep wound surgical site infection). Eight independent risk factors for wound complications resulted from the model and were assigned whole number integer risk scores. Summary risk scores were collapsed into categories and defined as low (0-3 points), moderate (4-7 points), high (8-11 points), and very high (>12 points). ResultsThe wound complication rate in the derivation data set was 9.7% (n = 1428). Predictors of wound complication included age ≤73 (odds ratio [OR], 1.25; 95% confidence interval [CI], 1.08-1.46), body mass index ≥35 kg/m2 (OR, 1.99; 95% CI, 1.68-2.36), non-Hispanic White (vs others: OR, 1.48; 95% CI, 1.30-1.69), diabetes (OR, 1.23; 95% CI, 1.10-1.37), white blood cell count >9900/mm3 (OR, 1.18; 95% CI, 1.03-1.35), absence of coronary artery disease (OR, 1.27; 95% CI, 1.03-1.35), operative time >6 hours (OR, 1.20; 95% CI, 1.05-1.37), and undergoing a femoral endarterectomy in conjunction with bypass (OR, 1.34; 95% CI, 1.14-1.57). In both the derivation and validation sets, wound complications correlated with risk category. Among the defined categories in the derivation set, wound complication rates were 4.5% for low-risk patients, 8.5% for moderate-risk patients, 13.8% for high-risk patients, and 23.8% for very high-risk patients, with similar results for the internal validation data set. Operative indication did not independently associate with wound complications. Patients with wound complications had higher rates of reoperation and graft failure. ConclusionsThis risk prediction model uses easily obtainable clinical metrics that allow for informed discussion of wound complication risk for patients undergoing open infrainguinal revascularization.

Transaxillary Capsulorrhaphy with Reimplantation to Correct Bottoming-Out Deformity in Breast Mycobacterial Periprosthetic Infection: A Case Report with Literature Review.

Augmentation mammoplasty is one of the most popular cosmetic surgeries, but there is a high reoperation rate (29.7%) commonly due to capsular contracture, implant malpositioning, infection, and unsatisfactory size. Although infection only accounts for 2% of cases, its management is very challenging, especially with nontuberculous mycobacteria (NTM) infection. Breast prosthetic NTM infection is a rare but is a disastrous condition with an incidence of approximately 0.013%. Immediate salvage reimplantation is usually not suggested, and most studies recommend a gap of 3 to 6 months after combination antibiotics therapy before reimplantation. However, delayed reimplantation often leads to great psychological stress and struggle between the doctor and patient. We present the case report of successful reimplantation in treating prosthetic NTM infections in a 28-year-old female. We discuss a novel technique "transaxillary capsulorrhaphy" to correct the bottoming-out deformity. One year after the combination of antibiotics and surgery, the follow-up computed tomography scan showed complete remission of NTM without recurrence. We discuss the surgical technique in detail. The 1-year follow-up assessment (photos and dynamic video) revealed good cosmesis and reliable correction using the new technique. This report is the first formal description and discussion of one-stage reimplantation following NTM infections. Transaxillary capsulorrhaphy allows for a successful salvage operation when an implant is displaced. This approach provides highly favorable result in eastern women undergoing revision augmentation mammoplasty. This study reflects level of evidence V, considering opinions of respected authorities based on clinical experience, descriptive studies, or reports of expert committees.

Association of obesity with high retears, and complication rates, and low functional scores after rotator cuff repair: a systematic review and meta-analysis.

Obesity influences the outcomes of orthopedic surgeries such as total knee arthroplasty and spinal surgery. However, the effect of obesity on the outcomes of rotator cuff repair is unknown. This systematic review and meta-analysis aimed to examine the effect of obesity on rotator cuff repair outcomes. PubMed, EMBASE, Web of Science, and Cochrane Library databases were searched to identify relevant studies published from their inception till July 2022. Two reviewers independently screened titles and abstracts using the specified criteria. Articles were included if they indicated the effect of obesity on rotator cuff repair and the related outcomes after surgery. Review Manager (RevMan) 5.4.1 software was used to perform statistical analysis. Thirteen articles involving 85497 patients were included. Obese patients had higher retear rates than nonobese patients (OR 2.58, 95% CI 1.23-5.41, P=0.01), lower American Shoulder and Elbow Surgeons (ASES) scores (MD: -3.59, 95% CI: -5.45-[-1.74]; P=0.0001), higher visual analog scale (VAS) for pain (MD: 0.73, 95% CI: 0.29-1.17; P=0.001), higher reoperation rates (OR 1.31, 95% CI 1.21-1.42, P<0.00001), and higher rates of complications (OR 1.57, 95% CI 1.31-1.87, P=0.000). Obesity did not affect the duration of surgery (MD: 6.03, 95% CI: -7.63-19.69; P=0.39) or external rotation (ER) of the shoulder (MD: -1.79, 95% CI: -5.30-1.72; P=0.32). Obesity is a significant risk factor for retear and reoperation after rotator cuff repair. Furthermore, obesity increases the risk of postoperative complications and leads to lower postoperative ASES scores and higher shoulder VAS for pain.

Endoscopic Versus Open In Situ Decompression for the Management of Cubital Tunnel Syndrome.

This study compared the results of endoscopic cubital tunnel release (eCuTR) with those of open cubital tunnel release (oCuTR) for the management of cubital tunnel syndrome (CuTS). In this retrospective study, 35 patients underwent eCuTR or oCuTR. Group I and group II consisted of 16 patients undergoing eCuTR and 19 patients undergoing oCuTR, respectively. Patients were asked to report paresthesia and pain, and electromyography was performed. The Dellon and Bishop classifications were used. The Disabilities of the Arm, Shoulder and Hand (DASH) and visual analog scale (VAS) pain scores were recorded, as well as the key pinch strength and two-point discrimination. The incision length and operation duration were noted. The mean follow-up was 39 months. The mean operating time was longer in the endoscopy group (43 vs 22 minutes). Overall, 34.3% (n=12) of the cases were classified as Dellon grade II and 65.7% (n=23) were classified as Dellon grade III. According to the Bishop score, excellent or good results were obtained for 75% of the patients in the eCuTR group and 78.9% of the patients in the oCuTR group. In the eCuTR and oCuTR groups, all outcome measures improved after surgery: DASH score (preoperative, 37.7 vs 30.7; postoperative, 15.4 vs 20), VAS score (preoperative, 7.8 vs 7.3; postoperative, 4.3 vs 4.1), pinch strength (preoperative, 74 vs 66; postoperative, 93 vs 84), and two-point discrimination (preoperative, 5.6 vs 6.6; postoperative, 4.9 vs 4.5). No significant difference was apparent between the two techniques in outcomes. However, the endoscopic release had a higher reoperation rate and took twice as long to perform despite having a shorter incision. [Orthopedics. 2024;47(3):e119-e124.].

Isolated Arthroscopic Debridement of Acetabular Labral Tears: High Rates of Failure and Conversion to Total Hip Arthroplasty at 13-Year Minimum Follow-up

Background: Historically, symptomatic hip labral lesions were treated with arthroscopic debridement. Hip labral repair has become the standard treatment for labral pathology; however, to date, there are limited long-term studies regarding the outcomes of isolated labral debridement. Purpose: To (1) evaluate the long-term patient-reported outcomes of isolated labral debridement, (2) report reoperation and arthroplasty rates, and (3) identify risk factors contributing to reoperation or poor clinical outcomes. Study Design: Case series; Level of evidence, 4 Methods: A retrospective review of a prospectively generated cohort of 59 hips in 57 patients from 1996 to 2010 who underwent hip arthroscopy with labral debridement was performed. Only patients with Tönnis grade <3 were included. Additionally, given the time period analyzed, resection of cam morphology was not performed, and the interportal capsulotomy was not repaired. The pre- and postoperative modified Harris Hip Score; Hip Outcome Score (HOS)-Activities of Daily Living and -Sports scores; and reoperation, conversion to total hip arthroplasty, and risk factors were analyzed. Results: In total, 48 hips in 47 patients (14 men, 33 women; mean age, 48.0 ± 12.9 years) met inclusion criteria and were followed for a mean of 17 ± 3 years (range, 13-27 years). The mean preoperative Tönnis grade was 1.3 ± 0.6 (range, 0-2), the mean chondral acetabular International Cartilage Regeneration & Joint Preservation Society (ICRS) grade was 1.7 ± 1.6 (range, 0-4), the mean chondral femoral ICRS grade was 0.9 ± 1.4, and the mean acetabular labral articular cartilage grade was 2.5 ± 1.2 (range, 0-4). At the final follow-up, mean the modified Harris Hip Score, HOS-Activities of Daily Living score, and HOS-Sports score were 82.2 ± 16.6, 81.9 ± 20.5, and 82.2 ± 20.5, respectively. Nineteen hips underwent subsequent reoperation at a mean of 5.5 ± 6.2 years (range, 0.5-21.2 years) postoperatively, including 16 hips (33% overall) being converted to total hip arthroplasty. Higher acetabular ICRS chondral grades at the time of surgery were observed in patients who went on to subsequent surgery compared with those who did not (2.3 ± 1.6 vs 1.1 ± 1.5; P = .02). In reoperation-free hips, Tönnis grade demonstrated a trend of increasing over time (1.4 preoperatively vs 1.7 at radiographic follow-up; P = .08). At the final follow-up, 19 hips (40%) had undergone reoperation, and 5 additional hips (10%) were rated as “abnormal” or “severely abnormal” in function, resulting in an overall clinical failure rate of 50%. Conclusion: Isolated labral debridement was found to result in high rates of failure and reoperation, with a third of patients being converted to arthroplasty and half of patients meeting criteria for reoperation or clinical failure. Of note, for patients remaining reoperation-free, satisfactory outcome scores were observed.

(Epi)genotype and Timing of Tongue Reduction Predict Safety and Long-Term Outcomes in Beckwith-Wiedemann Syndrome.

Macroglossia is a cardinal feature of Beckwith-Wiedemann syndrome (BWS) with a clinical spectrum where the indication and timing for surgery remain to be validated. This study leverages a cohort of molecularly characterized patients with BWS to correlate epigenetic diagnosis with phenotype and treatment outcome. Patients with BWS seen in consultation for macroglossia from 2009-2022 were reviewed for phenotype, molecular diagnosis, tongue reduction status, timing of surgery (early = under 12 months), and perioperative complications. Two hundred thirty-seven patients were included. Imprinting control region 2 loss of methylation (IC2 LOM) was the most common epigenotype (61%). Paternal uniparental isodisomy for chromosome 11 (pUPD11) comprised a larger proportion of patients undergoing tongue reduction (18%) than those not undergoing surgery (8%, p = 0.024) and was associated with need for repeat surgery (OR 4.49, 95% CI 1.06-18.98, p = 0.041). Complications including wound dehiscence, ventilator associated pneumonia, and unplanned extubation were more common in patients undergoing early surgery (20%) than late surgery (4%, OR 5.70, 95% CI 1.14-28.55, p = 0.034). This study presents one of the largest cohorts correlating molecular diagnosis with clinical course of macroglossia treatment in BWS. Macroglossia in patients with pUPD11 is associated with higher rates of reoperation. Relief of obstructive sleep apnea with early tongue reduction must be weighed against risk of perioperative complications, most of which are non-surgical. This study highlights how molecular diagnosis advances clinical care by risk stratifying clinical outcomes in a center providing integrated multidisciplinary care for the BWS population.

Increased Metal Component Failure with STAR Total Ankle

Category: Ankle Arthritis Introduction/Purpose: With the increasing total ankle arthroplasty (TAA) literature, there is a need to further examine the outcomes across a wide variety of implants. The purpose of this study is to review the existing literature and identify trends among current individual TAA implants. Methods: A comprehensive search of MEDLINE for all articles published between 1996 and 2021 was conducted with a minimum two-year mean follow-up. Two reviewers evaluated each study to determine whether it was eligible for inclusion and abstracted the data of interest. Meta-analytic pooling of group results across studies was performed, examining for individual implant survival and component failure. Seventy-three implant groups met inclusion criteria (3rd and 4th generation implants only), composed of STAR (20), Salto (mobile bearing) (10), Salto Talaris (11), Hintegra (8), Zimmer (6), INBONE II (6), INBONE I (4), Infinity (4), Cadence (4). 41 groups (56.2%) were implanted with mobile bearing devices and 32 (43.8%) with fixed bearing implants. In total, 6498 subjects were included with a mean age of 61.77 years and mean BMI of 28.5 kg/m2. At mean follow-up of 62.2 months, the overall reoperation rate was 21.13% and metal component revision rate was 10.16%. Results: Multivariate analysis of all implants, controlling for follow-up duration, found a statistically significant difference in the metal component survival rate (p=.036) and reoperation rate (p=.007) with the STARs TAAs surviving significantly worse and undergoing reoperation at a significantly higher rate than all other implants. There was no statistically significant difference in the rate of metal component revision (p=.768), tibial component failure rate (p=.095), or talar component failure rate (p=.089). Analysis of the Salto Talaris vs Salto found a significant difference in metal component survival rate (Salto=90.68%, Salto Talaris=97.81%; p=.002). Lastly, analysis of the INBONE I vs II implants found INBONE I had a significantly greater rate of revision due to metal component failure (INBONE I=9.8%, INBONE II=3.4%; p=.002). Conclusion: Based on current literature, it appears that the STAR total ankle implant has a statistically significantly lower rate of metal component survival and higher rate of reoperation than the other 3rd and 4th generation implants examined, even when controlling for study follow-up duration. The fixed bearing Salto Talaris had statistically significantly better survival rate than the mobile bearing Salto. These findings are important to physicians when considering implants for total ankle arthroplasty.

Clinical Comparison of Internal Fixation Constructs in Midfoot Charcot Arthropathy

Category: Diabetes; Midfoot/Forefoot Introduction/Purpose: Midfoot Charcot can lead to instability, deformity and ultimately ulceration that can be limb threatening. Previous authors have described a variety of surgical stabilization techniques and constructs including intramedullary fixation (“beaming”) across the midfoot in varying orientations. More recently, intramedullary compression nails (“IM nail”) have been introduced. In contrast with static screws, these devices provide compression across the joints of the midfoot by engaging a compression mechanism against a fixed interlock screw. To our knowledge no clinical comparison between traditional beaming techniques and modern compression nails for midfoot Charcot has been reported. We hypothesize that using IM nails will result in a higher union rate, and lower reoperation and hardware failure rates. Methods: Our electronic medical record was queried to identify patients from 2016-2021 who underwent midfoot reconstruction. Only patients with midfoot Charcot who underwent extended intramedullary fixation were included. Patients with active ulceration at the time of surgery, Charcot that included the ankle, or external fixation as part of the construct were excluded. IM nails were used exclusively for medial column constructs. Basic demographic information was collected. Radiographs and operative notes were evaluated and construct type and implants used were noted. Radiographs at final follow-up were evaluated for union and hardware complication. Clinical notes were evaluated for weightbearing status, plantigrade foot position, ulceration, and wound care requirements. Finally, all complications and reoperations were recorded. Chi-squared or Fisher’s Exact tests were used as appropriate to compare categorical variables and t-tests were used to compare numerical variables. Results: 48 feet (47 patients) with a median age of 58 years (IQR 50, 64) were included. Diabetes was the Charcot etiology in 34/48 (70.8%) feet. There were 19 beaming and 29 IM nail constructs. Basic demographics and Brodsky classification were equally distributed (p&gt;0.05). Median follow-up time was 1.3 years (IQR 0.8, 2.9). Combined medial and lateral column fixation was performed in 39/48 (81.3%) patients. 52% (25/48) included subtalar arthrodesis. Beaming constructs had higher re-operation rates (57.9% versus 27.6%, p &lt; 0.05), and higher hardware failure rates (57% versus 6.9%, p&lt; 0.001). IM nail group had higher union rates (75.9% versus 31.6%, p = 0.001), and higher rates of full weight-bearing at final follow up (86.2% versus 68%, p &lt; 0.05). Two (4.2%) patients required amputation. Conclusion: In a cohort of 48 feet undergoing midfoot Charcot reconstruction, the use of medial column IM nails was associated with lower reoperation rates, lower rates of hardware failure, higher union rates, and higher rates of full weightbearing at final follow-up compared with traditional screw fixation. Surgeons who treat midfoot Charcot may consider these results when planning their stabilization constructs in this high-risk patient population.

Outcomes After Hallux Interphalangeal Joint Arthrodesis.

Hallux interphalangeal joint arthrodesis (HIPJA) is indicated for a variety of pathologies. Despite high nonunion rates, techniques remain unchanged. The aim of this study is to examine nonunion and complication rates and describe risk factors for treatment failure. A query of an institutional database was performed to identify all patients undergoing HIPJA procedure over a 10-year period. Records were reviewed to the procedure, evaluate patient factors, indications, and radiographic/clinical arthrodesis. Radiographic union was defined as 2 cortical continuations or bridging at the arthrodesis site, absence of hardware failure, and the absence of lytic gapping of the arthrodesis. Clinical fibrous union was defined as radiographic nonunion with painless toe range of motion and physical examination consistent with fusion across the interphalangeal joint. Two hundred twenty-seven primary HIPJA procedures were identified. Our cohort demonstrated a 25.5% nonunion rate (58/227) and 21.1% reoperation rate (48/227). Patients with diabetes were at higher risk for nonunion (P = .014), but no significant differences were identified based on smoking status or diagnosis of inflammatory arthritis. No difference was seen between implant groups: single screw, multiple screws, screw plus other fixation, nonscrew fixation. Patients with prior hallux metatarsophalangeal joint arthrodesis did not have a significantly higher nonunion rate than patients without prior first metatarsophalangeal joint arthrodesis. Patients diagnosed with radiographic nonunion were at higher risk for reoperation (P < .0001). Our cohort represents the largest single-center series of HIPJA procedures published to date. We found relatively high nonunion and reoperation rates with standard current techniques. Level III, retrospective case series.
