Diagnostic performance of an AI algorithm for the detection of appendicular bone fractures in pediatric patients

PurposeTo evaluate the diagnostic performance of an Artificial Intelligence (AI) algorithm, previously trained using both adult and pediatric patients, for the detection of acute appendicular fractures in the pediatric population on conventional X-ray radiography (CXR). Materials and methodsIn this retrospective study, anonymized extremities CXRs of pediatric patients (age <17 years), with or without fractures, were included. Six hundred CXRs (maintaining the positive-for-fracture and negative-for-fracture balance) were included, grouping them per body part (shoulder/clavicle, elbow/upper arm, hand/wrist, leg/knee, foot/ankle). Follow-up CXRs and/or second-level imaging were considered as reference standard. A deep learning algorithm interpreted CXRs for fracture detection on a per-patient, per-radiograph, and per-location level, and its diagnostic performance values were compared with the reference standard. AI diagnostic performance was computed by using cross-tables, and 95 % confidence intervals [CIs] were obtained by bootstrapping. ResultsThe final cohort included 312 male and 288 female with a mean age of 8.9±4.5 years. Three undred CXRs (50 %) were positive for fractures, according to the reference standard. For all fractures, the AI tool showed a per-patient 91.3% (95%CIs = 87.6–94.3) sensitivity, 76.7% (71.5-81.3) specificity, and 84% (82.1–86.0) accuracy. In the per-radiograph analysis the AI tool showed 85% (81.9–87.8) sensitivity, 88.5% (86.3–90.4) specificity, and 87.2% (85.7–89.6) accuracy. In the per-location analysis, the AI tool identified 606 bounding boxes: 472 (77.9 %) were correct, 110 (18.1 %) incorrect, and 24 (4.0 %) were not-overlapping. ConclusionThe AI algorithm provides good overall diagnostic performance for detecting appendicular fractures in pediatric patients.

Treatment methods in idiopathic avascular necrosis of the scaphoid - review

IntroductionIdiopathic avascular necrosis (AVN) of the scaphoid is commonly known as Preiser’s disease (PD). It is a rare condition with symptoms such as pain, swelling around the scaphoid area and a reduced range of motion of the wrist. This condition occurs in the absence of an acute fracture or a fracture non-union. The disease can be diagnosed using classic radiology, magnetic resonance imaging or computed tomography. Treatment methods include surgical nad non-surgical procedures.AimMain aim of the paper was to summarize most recent knowledge about treatment methods in idiopathic AVN of the scaphoid.Material and methodsTo conduct this review, we searched the databases for articles about PD. We used keywords ‘Preiser disease’ and ‘idiopthic avascular necrosis scaphoid’. Our focus was on articles published in between 2017 and 2023, as we wanted to focus on most recent publications.Results and discussionMain goals of the treatment of PD are pain relief, improved hand grip strength, wider range of motion of the wrist and enhanced overall hand and wrist function. Implementing conservative management seems not to bring satisfactory results in patients with PD. Various surgical routines are the treatment of choice.ConclusionsStage I of the disease is the most likely treated with bone-grafting or currettage. Method of choice in stage II is vascularized bone graft, in stage III – proximal row carpectomy. Due to the rarity of the disease, there are no established recommendations regarding the treatment. Further studies are needed to extend the knowledge of the disease and potential methods of its management.

Therapeutic efficacy of platelet-rich plasma in the management of rib fractures.

This study aimed to investigate the therapeutic efficacy of platelet-rich plasma (PRP) therapy in patients with rib fractures. This study retrospectively collected data from patients with acute rib fractures at Ming-Sheng General Hospital from 2020 to 2022 and excluded those who underwent surgical intervention or with severe extrathoracic injuries. PRP was extracted using the patient's blood and injected via ultrasound guidance near the fracture site. Patients self-assessed pain levels and medication usage at 0, 1, 2, 4, and 8 weeks. Pulmonary function tests were conducted at 4 weeks. This study included 255 patients, with 160 and 95 patients in the conservative (only pain medications administered) and PRP groups (PRP and analgesics administered), respectively. The PRP group reported lower pain levels than the conservative group at 2 and 4 weeks. No substantial differences in medication usage were observed between the groups. The PRP group demonstrated lower pain levels and medication usage than the conservative group in severe rib fractures (≥3 ribs) and better lung function improvement at 4 weeks. After propensity score matching, the PRP group still had a better treatment outcome in pain control and lung function recovery. PRP demonstrated considerable therapeutic efficacy in patients with severe rib fractures, resulting in reduced pain, decreased medication usage, and improved lung function but with no substantial benefits in patients with mild rib fractures.

Clinical outcomes of total hip arthroplasty after femoral neck fractures vs. osteoarthritis at one year follow up—A comparative, retrospective study

PurposeThe objective of the study is to determine if there was a difference in medical complications and in-hospital mortality among the patients who underwent THA for femoral neck fracture relative to same procedure for elective patients with coxarthrosis.MethodsWe compared characteristics and short-term outcomes during the rehabilitative postsurgical period. We included all patients older than 45 years who underwent THA for primary/secondary hip arthritis and displaced femoral neck fractures type Garden III and IV. Clinical examination, functional outcome and radiographic evaluation were performed during follow-up. Patients were evaluated at the following time points: preoperatively, postoperatively at three days, six weeks, 12 weeks and one year and we registered Visual Analogue Scale (VAS) pain score, Harris Hip Score (HHS), the Western Ontario McMaster Osteoarthritis Index (WOMAC), internal and external rotation of the hip and operated limb length compared with the opposite.ResultsThere is no significant statistically differences between the two groups regarding the preoperative comorbidities. The frequencies of patients experiencing in-hospital and 30-day postoperative complications were generally low and same in groups we studied. The mean quantity of surgical blood loos during the operation was significantly higher in the hip fracture group compared with elective patient group with OA (340.09 ± 86.03 vs 309.43 ± 102.52). With respect to postoperative recovery the patients with THA after FNF were mobilized by active walking a little bit faster as the patient with OA (2.77 ± 1.18 days vs 3.1 ± 1.14 days). The average inpatient hospital length of stay after THA for OA was 11.07 days compared to 13.41 days following a THA for FNF.ConclusionOur study showed that THA for treatment of an acute fracture of the femoral neck in an elderly patient can provide results comparable to those of patients who received THA for OA and we found that the results are similar.

Total Knee Replacement as Primary Management in Comminuted Tibial Plateau Fracture in Elderly Patients: A Systematic Review and Meta-Analysis

Abstract Background Fracture of the tibial plateau represents approximately 8% of fractures in elderly patients. These injuries occur with an estimated incidence of 13.3 per 100,000 adults annually, with nearly a quarter of these occurring in elderly patients with concomitant osteoporosis. In young patients, the mainstay treatment for displaced tibial plateau fracture is open reduction and internal fixation (ORIF). However, in elderly patients with periarticular fracture, the combination of poor bone quality, metaphyseal bone comminution, and friable soft tissue envelope creates unique challenges to traditional ORIF. Aim of the Work To evaluate the perioperative complication rates and clinical outcomes in patients following TKA for primary treatment of tibial plateau fracture and to establish whether TKA can be considered a reliable primary treatment option in selected individuals. Patients and Methods The present systematic review will be performed in accordance with the preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search for all level I–IV evidence published articles using the online databases MEDLINE, Embase, and PubMed will be performed. The purpose of this search is to identify all eligible studies featuring perioperative complications or clinical outcomes in patients following TKA for primary treatment of tibial plateau fracture. Results The immediate management of acute tibial plateau fracture in elderly patients continues to be controversial. Although there is emerging evidence showing positive results for primary TKA for tibial plateau fracture, it is paramount to appreciate that performing TKA in the context of acute tibial plateau fracture is not a straightforward attempt. Many of these patients have notable loss of the articular surface, which disrupts normal anatomic references, and compromised soft tissue due to possible coexisting ligamentous injury. Conclusion Total knee arthroplasty for treatment of acute tibial plateau fracture is an enticing alternative to ORIF to allow early weight bearing, especially in elderly patients with poor bone quality and a friable soft tissue envelope. Our systematic review shows that functional scores are only average.

Short-Term Results after Reversed Total Shoulder Arthroplasty

Abstract Purpose Massive rotator cuff tear, with or without arthritis and proximal humerus fracture non-union or malunion, lead to the loss of center of rotation of shoulder, while anatomical total shoulder arthroplasty does not provide a stable center of rotation, Therefor reversed total shoulder arthroplasty (RTSA) is the suitable method for these indications, as well as in elderly patients with primary glenohumeralosteoarthritis because anatomical total shoulder arthroplasty has the risk of failure either due to loosening of glenoid component or cuff tear. This study aimed to determine the short-term results after RTSA in patients a with massive cuff tear, acute proximal humerus fracture, proximal humerus fracture malunion or non- union, and primary glenohumeralosteoarthritis. Methods This one arm clinical trial (interventional study) conducted in Ain Shams University Hospitals included 16 patients who underwent RTSA. Short-term outcomes included constant score, American Shoulder and Elbow Surgeon (ASES) score, and range of motion (ROM). Patients with rotator cuff arthropathy, massive irreparable cuff tear with or without glenohumeralarthritis, elderly patients with acute complex proximal humerus fracture, malunited or nonunited proximal humerus fracture, and patients with glenohumeralosteoarthritis were included. Patients who were aged &amp;lt;50 years were excluded, as well as patients with axillary nerve injury or deltoid muscle dysfunction. Results This study included 16 patients, including 8 males and 8 females. The mean age was 64.19 years and the duration of follow up-was 1 year postoperatively. Seven Patients with massive irreparable cuff tear were included, of them, 1 had associated anterior shoulder instability and recurrent anterior dislocation, 3 had a four-part proximal humerus fracture, 2 had fracture dislocation, 2 had proximal humerus fracture non –union, 1had neglected dislocation, and 2 had glenohumeralosteoarthritis. Outcomes were followed using constant and ASES scoring systems, and ROM. The global postoperative gain was statistically significant (p &amp;lt; 0.001). Complication in the form of dislocation occurred in one case that had RTSA after fracture non-union. Conclusion Good clinical and functional outcomes were achieved after RTSA, not only for classic massive cuff tear indication, but for other disorders, such as acute proximal humerus fracture, fracture non-union, and primary glenohumeralosteoarthritis. However, the outcomes after irreparable cuff tear were the best among all indications, while fracture non-union had the least improvement in clinical outcomes. Improvements in prosthesis design, surgeon’s experience, and clinical results are necessary to optimize this treatment for many shoulder conditions.

Short-Term Results after Reverse Total Shoulder Arthroplasty

Abstract Background: The loss of the shoulder’s center of rotation is caused by massive rotator cuff tears, which can occur with or without arthritis and proximal humerus fractures that are nonunion or malunion. Because anatomical total shoulder arthroplasty cannot provide a stable center of rotation, reverse total shoulder arthroplasty (RTSA) is the appropriate procedure for these indications and in older patients who have primary glenohumeral osteoarthritis. Anatomical total shoulder arthroplasty carries a risk of failure because of the loosening of the glenoid component or cuff tear. The purpose of this study was to determine the short-term outcomes following RTSA in patients who had primary glenohumeral osteoarthritis, acute proximal humerus fractures, malunited or nonunited proximal humerus fractures, and massive cuff tears. Materials and Methods: This single-arm clinical trial (interventional study) was done in Ain Shams University Hospitals; 16 patients were included who underwent RTSA. Constant score, American Shoulder and Elbow Surgeon score, Visual Analog Scale score, and range of motion (ROM) were the short-term outcomes. Patients with cuff tear arthropathy, irreparable cuff tear with or without glenohumeral arthritis, elderly patients with unreconstructable proximal humerus fracture, proximal humerus fracture malunion or nonunion, and patients with glenohumeral osteoarthritis were included. Patients under the age of 50, as well as those with deltoid muscle dysfunction or injuries to the axillary nerve, were excluded. Results: There were 16 patients in this study, 8 of whom were male and 8 of whom were female. The follow-up period lasted 2 years following surgery, with a mean age of 64.19 years. The study included 7 patients with irreparable cuff tears one of them had associated anterior shoulder instability and recurrent anterior shoulder dislocation. One patient had a neglected shoulder dislocation, two patients had proximal humerus fracture dislocation, two patients had a nonunited proximal humerus fracture, three patients had unreconstructable proximal humerus fracture, and two had glenohumeral osteoarthritis. Conclusion: Not only did RTSA provide good clinical and functional outcomes for the standard indication of a massive cuff tear, but it also proved beneficial for other disorders such as primary glenohumeral osteoarthritis, nonunited fracture, and acute proximal humerus fracture. Among all indications, irreparable cuff tears yielded the highest results; nonunited fractures displayed the least improvement regarding clinical outcomes. Enhancements in the design of prostheses, the expertise of surgeons, and clinical outcomes are crucial to maximize their effectiveness in treating various shoulder disorders.

Arthroscopically Assisted Technique in the Treatment of Ankle Fractures with Posterior Malleolus Fragment in Adults

Abstract Introduction: Ankle fractures constitute a challenging condition due to its high impact on the long term. Thus, advancements in management have been proposed to ensure the best possible outcome. Hence, we aimed to assess the role of arthroscopy in the treatment of ankle fractures that involve posterior malleolus fragments in adults. Patients and Methods: In a quasi-experimental, interventional, prospective, nonrandomized study, we included 16 adult patients with acute ankle fracture with posterior malleolus fragment. They underwent arthroscopically assisted technique for their fracture treatment. A standard systematic arthroscopic ankle examination, their fracture grade, and classification were assessed, and subsequent management was conducted. The patients were followed up for 6 months using the American Orthopedic Foot and Ankle Society (AOFAS) score and radiographic monitoring with standard X-ray. Results: The mean AOFAS score improved significantly after 6 months of follow-up (from 84.81 in the 3rd month to 92.81 in the 6th month). Ankle dorsiflexion angle and ankle plantar-flexion angle showed a gradual increase during follow-up, reaching 17.31° ± 3.25° and 45° ± 5°, respectively. Only two patients developed complications. Age, body mass index, and grade of the osteochondral lesion were negatively correlated statistically significantly with the AOFAS score. This proves the effective role of arthroscopically assisted technique in the treatment of ankle fractures with posterior malleolus fragment. Conclusion: Arthroscopically assisted technique in the treatment of ankle fractures with posterior malleolus fragment in adults resulted in good functional outcomes with less complications and it allows the assessment of associated intra-articular injuries. Further studies with longer follow-up periods are needed for the assessment of outcomes and complications for comparison.

Effectiveness over time of the reverse shoulder prosthesis for acute proximal humeral fracture

Reverse shoulder arthroplasty (RSA) has proven to be an effective surgical procedure for irreparable rotator cuff tears, comminuted fractures of the proximal humerus and shoulder arthroplasty revision surgeries. We know from the literature that the functional results are good in the short term, but not whether these results remain stable in the long term or, on the contrary, show a deterioration in functionality. This study aims to analyze the functionality, degree of satisfaction, complications, and prosthesis survival at different cut-off points in patients with complex proximal humerus fractures treated with RSA, with a minimum postoperative follow-up of 7 years. Analytical, longitudinal and prospective observational study of a cohort of patients treated for a fracture of the proximal humerus with PIH. Functional outcome was assessed using the Constant scale and the Constant adjusted for age and gender of the patients. Quality of life was measured using the University of California at Los Angeles Shoulder Assessment scale (UCLA) and the Disability of the Arm, Shoulder and Hand score scale (QuickDASH). In addition, range of motion, pain and radiological variables of loosening, scapular notching and tuberosity consolidation were assessed. Thirty-three patients were included with a mean postoperative follow-up of 8.3 years (range 7-12 years). There was a progressive and significant decrease in Constant score at 5and7years follow-up compared to the baseline assessment 2 years after surgery, although the effect size was not significant. The age- and sex-adjusted Constant as well as the UCLA scale did not show statistically significant variations at follow-up. Both shoulder abduction and anterior shoulder flexion correlated well with the final QuickDASH score. Radiological variables did not influence any of the study outcome variables. The functionality and quality of life of patients with complex proximal humerus fractures treated with RSA decreased significantly compared to the 2-year evaluation, although this change was not clinically relevant. Survival of RSA was satisfactory in the medium to long term with a low complication rate.

Sodium-Glucose Transporter 2 Inhibitors in Heart Failure: An Overview of Systematic Reviews.

Background: Several studies have shown that sodium-dependent glucose transporter 2 inhibitors can be used in the treatment of heart failure. This article summarized systematic reviews of sodium-dependent glucose transporter 2 inhibitors in the treatment of heart failure in order to evaluate efficacy and safety. Methods: We systematically searched eight electronic databases from inception to July 2023. We used Assessment of Multiple Systematic Reviews 2 to evaluate the methodological quality, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 to assess report quality, Risk of Bias in Systematic Review to assess the risk of bias, and Grading of Recommendations Assessment, Development, and Evaluation to rate the quality of evidence. Outcome: A total of 36 systematic reviews were included. Our results were classified as clear evidence of benefit: hospitalization for heart failure; possible benefit: cardiovascular death (mortality) and renal outcome composite; clear evidence of no effect or equivalence: atrial arrhythmias, ventricular arrhythmia, atrial fibrillation, and hypotension; possible harm: genital infection; insufficient evidence to draw a conclusion: atrial flutter, major adverse cardiovascular events, urinary tract infection, acute kidney injury, hypoglycemia, and bone fracture. Conclusions: Sodium-dependent glucose transporter 2 inhibitors are beneficial for the treatment of heart failure, especially in terms of heart failure hospitalization.

Artificial neural networks for the detection of odontoid fractures using the Konstanz Information Miner Analytics Platform.

An experimental study. This study aimed to investigate the potential use of artificial neural networks (ANNs) in the detection of odontoid fractures using the Konstanz Information Miner (KNIME) Analytics Platform that provides a technique for computer-assisted diagnosis using radiographic X-ray imaging. In medical image processing, computer-assisted diagnosis with ANNs from radiographic X-ray imaging is becoming increasingly popular. Odontoid fractures are a common fracture of the axis and account for 10%-15% of all cervical fractures. However, a literature review of computer-assisted diagnosis with ANNs has not been made. This study analyzed 432 open-mouth (odontoid) radiographic views of cervical spine X-ray images obtained from dataset repositories, which were used in developing ANN models based on the convolutional neural network theory. All the images contained diagnostic information, including 216 radiographic images of individuals with normal odontoid processes and 216 images of patients with acute odontoid fractures. The model classified each image as either showing an odontoid fracture or not. Specifically, 70% of the images were training datasets used for model training, and 30% were used for testing. KNIME's graphic user interface-based programming enabled class label annotation, data preprocessing, model training, and performance evaluation. The graphic user interface program by KNIME was used to report all radiographic X-ray imaging features. The ANN model performed 50 epochs of training. The performance indices in detecting odontoid fractures included sensitivity, specificity, F-measure, and prediction error of 100%, 95.4%, 97.77%, and 2.3%, respectively. The model's accuracy accounted for 97% of the area under the receiver operating characteristic curve for the diagnosis of odontoid fractures. The ANN models with the KNIME Analytics Platform were successfully used in the computer-assisted diagnosis of odontoid fractures using radiographic X-ray images. This approach can help radiologists in the screening, detection, and diagnosis of acute odontoid fractures.

Time trends in proximal humeral fractures from 1944 to 2020 – A cohort study in Malmö, Sweden

BackgroundMost studies infer increasing incidence of proximal humeral fractures (PHF) from the 1950´s until the 1990´s. Recent time trends are less clear.ObjectivesOur primary objective was to identify time trends in the age- and sex-adjusted adult incidence of PHF in Malmö, Sweden, from year 1944 until 2020. Our secondary objectives were to describe the variation in incidence according to age, the monthly distribution, and to compare data from the two most recent decades with earlier.Study design and methodsMalmö has one emergency hospital where acute fractures are treated. We identified PHF in adult patients (≥ 18 years) by reviewing relevant radiology examinations during 17 sample years from year 1944 to 2020. We used jointpoint analyses to estimate time trends.ResultsWe identified 3 031 PHF during the study period (3 231 161 person years), 73% were sustained by women with mean age of 69 years (mean age in men 59). Joinpoint analyses indicated an increase in the age- and sex-adjusted incidence of PHF from year 1944 (52 per 100 000 person years) until 1977 (120 per 100 000) and thereafter a decrease until 2020 (85 per 100 000). A seasonal variation with more fractures during winter months, was apparent in earlier but not recent decades.ConclusionsThe age- and sex-adjusted incidence of PHF increased in Malmö, Sweden, from the 1940´s until year 1977 and thereafter decreased until 2020. More fractures were seen during winter months in earlier but not recent decades.

Enhancing the Ilizarov Apparatus: Mechanical Stiffness

The Ilizarov system is a form of external fixation device utilized by medical professionals to aid patients who have sustained injuries from accidents, bone shortening, or nonunion of the bone. The device is fixed onto the long bone of the patient and is adjusted according to the nature of the injury. Ilizarov's techniques are minimal invasiveness, not aggressive, spare tissues and involve little blood loss. It consists of wires that are secured to a modular circular frame and then tightened. The Ilizarov fixator is a valuable tool for treating acute fractures, especially in cases where there is bone loss and compromised soft tissue. Several studies have aimed to improve the effectiveness of Ilizarov fixation through modifications to its frame components, such as ring diameter, transosseous element diameter, ring separation, transosseous element count in each ring, and number of rings, as well as the type of transosseous element employed, including wires, full-pins, or half-pins. Furthermore, positioning of transosseous elements at the correct crossing angle without damaging the nerves and vessels while considering the intricacy of bone deformities. Recent advancements in Ilizarov fixation will be thoroughly reviewed in this manuscript, with a particular focus on improving the stiffness of the entire frame. The main objective of this review is to pinpoint the optimal configurations, with a particular focus on stiffness, in order to foster stability and ensure a successful recuperation.

Demographic Characteristics and Factors Associated with Acute Scaphoid Fractures: An Analysis of 903 Patients

Objectives A comprehensive understanding of the epidemiology of scaphoid fractures is crucial to aid in diagnosing and treating patients with suspected injuries. The study aims to assess demographic characteristics and factors associated with acute scaphoid fractures in adults. Methods A retrospective review identified all patients with acute scaphoid fractures over four years at a single institution. Data collected included baseline demographics (age, biological sex, race, and ethnicity), body mass index, tobacco and alcohol use, pertinent medical history, and treatment modality. Laterality, location, and displacement of the fracture were confirmed on radiographic analysis. Results A total of 903 scaphoid fractures were included. The majority of fractures occurred in males (n=570, 63%) and were in the left hand (54%), unilateral (99%), nondisplaced (71%), and treated definitively with nonoperative management (71%). Nearly two-thirds (66%) of fractures occurred along the scaphoid waist, followed by the distal third of the scaphoid (25%). Proximal third fractures accounted for the smallest proportion of scaphoid fractures (8.6%) but had the highest displacement and surgical intervention rates compared to waist and distal third fractures. Younger age, male sex, fractures of the proximal third, and displaced fractures had higher odds of being treated surgically. Conclusion The scaphoid is one of the most frequently fractured carpal bones. Young adult males may be at an increased risk for injury. Patients with displaced fractures and those involving the proximal third require surgical intervention at higher rates.

International trends in shoulder replacement: a meta-analysis from 11 public joint registers.

International variation exists in the types of shoulder replacement used for treatment of specific diseases. Implant choice continues to evolve without high-quality evidence. Our aim was to evaluate trends in incidence rates of shoulder replacement and assess any recent changes in practice between countries by using registry data. Patient characteristics, indication and year of surgery, type of replacement, and collection methods of patient-reported outcomes (PROMs) was extracted from 11 public joint registries. Meta-analyses examined use of reverse total shoulder replacement (RTSR) for osteoarthritis, cuff tear arthropathy, and acute fracture; use of anatomical total shoulder replacement (TSR) for osteoarthritis; and use of humeral hemiarthroplasty for fracture. The annual growth rate of shoulder replacements performed is 6-15% (2011-2019). The use of RTSR has almost doubled (93%). RTSR is now universally performed for cuff tear arthropathy (97.3%, 95% confidence interval [CI] 96.0-98.1). Its use for avascular necrosis, trauma, and inflammatory arthropathy is increasing. The use of RTSR was similar (43.1%, CI 30.0-57.2) versus TSR (44.7%, CI 31.1-59.1) for osteoarthritis. The types of PROMs used, collection time points, and response rates lack standardization. COVID-19 had a varying inter-registry impact on incidence rates. The incidence of shoulder replacements has grown. Use of RTSR has increased for all disease indications despite limited high-quality evidence driving this change in indications outside of cuff arthropathy. Consequently, less variation is observed in international practice. Existing differences now relate to use of newer implant types and methodology of PROMs collection, which prevents international comparison and outcome analysis.

Hemiarthroplasty for irreparable distal radius fractures in the elderly: A comprehensive review.

Elderly patients maintaining functional independence can now be candidates for primary wrist hemiarthroplasty to manage acute irreparable distal radius fractures (DRFs). However, further investigation with long-term follow-up is required to validate these initial findings. To review the literature on the outcomes of distal radius hemiarthroplasty with available implants to assess its viability as a treatment option. A comprehensive review of the literature was conducted using electronic databases, including PubMed, Medline, and Scopus. The search terms employed were "distal radius fracture" , "hemiarthroplasty" , "wrist arthroplasty" , and related terminology. The search was restricted to articles published in English from 1980 until June 2023. Inclusion criteria encompassed cases or case series of DRF treated with hemiarthroplasty, providing clinical or radiographic outcomes, and published in peer-reviewed journals. A total of 2508 articles from PubMed and 883 from Scopus were identified initially. Following screening and removal of duplicates, 13 articles met the inclusion criteria. These articles, predominantly clinical retrospective studies, provided insights into hemiarthroplasty outcomes, including functional improvements and complications. Hemiarthroplasty was a treatment option for complex DRF, particularly those cases with severe comminution, intraarticular involvement, or severe osteoporosis. Functional outcomes demonstrated improvements in pain relief, wrist mobility, and grip strength, with variability across studies. Complications included implant loosening, infection, nerve injury, and stiffness, with varying incidence rates influenced by surgical techniques and implant choice. Long-term outcomes were inadequately documented, warranting further research. Hemiarthroplasty is a promising treatment for irreparable DRF in the elderly. Long-term outcomes and complications require further study.

Modified arthroscopic repair of a posterior cruciate ligament tibial avulsion fracture improves IKDC and Lysholm score compared to open reduction

PurposeThe purpose of this study was to analyse the difference between arthroscopic fixation and open reduction internal fixation (ORIF) of posterior cruciate ligament (PCL) tibial avulsion fractures.MethodsThis retrospective study analysed patients with an acute PCL tibial avulsion fracture who underwent surgical treatment at our hospital and follow-up for at least 24 months. Variables based on sex, age, Meyers–McKeever type, surgical method, meniscus tear, external fixation, labour or sports, Lysholm knee score, IKDC score, and KT-1000 value were also recorded. Multifactor unconditional logistic regression and Student’s t test with 1:1 propensity score matching (PSM) to remove confounding factors were used for analysis.ResultsSixty-five cases achieved knee function graded as “good” or better, and 9 cases not. Single-factor analysis indicated that Meyers–McKeever type (χ2 = 4.669, P = 0.031) and surgical approach (χ2 = 9.428, P = 0.002) are related to functional outcomes. Multifactorial logistic regression analysis further confirmed that Meyers–McKeever typing (OR = 10.763, P = 0.036, [95% CI 1.174–98.693]) and surgical approach (OR = 9.274, P = 0.008, [95% CI 1.794–47.934]) are independent risk factors affecting prognosis. In addition, PSM verified significant differences in the Lysholm score (t = 3.195, P = 0.006), IKDC score (t = 4.703, P = 0.000) and A-KT/H-KT (t = 2.859, P = 0.012). However, the affected-side KT-1000 value (A-KT, mm, t = 1.225, P = 0.239) and healthy-side KT-1000 value (H-KT, mm, t = 1.436, P = 0.172) did not significantly differ between the two groups. The proportions of cases in which the Lysholm score, IKDC and A-KT/H-KT exceeded the minimal clinically important difference (MCID) were 62.5% (20/32), 62.5% (20/32) and 93.75% (30/32), respectively.ConclusionCompared with ORIF, an arthroscopic approach for PCL tibial avulsion fractures achieves better results.Level of evidence: Retrospective cohort study; Level II.

Sustained IL-6 and sTNF-αR1 levels after hip fracture predict 5-year mortality: A prospective cohort study from the Baltimore Hip Studies.

Persistent inflammation is associated with adverse health outcomes, but its impact on mortality has not been investigated previously among hip fracture patients. This article aims to investigate the influence of changes in levels of cytokines in the 2 months after a hip fracture repair on 5-year mortality. This is a prospective cohort study from the Baltimore Hip Studies (BHS) with 191 community-dwelling older men and women (≥65 years) who had recently undergone surgical repair of an acute hip fracture, with recruitment from May 2006 to June 2011. Plasma interleukin-6 (IL-6), soluble tumor necrosis factor alpha receptor1 (sTNFα-R1), and interleukin-1 receptor agonist (IL-1RA) were obtained within 22 days of admission and at 2 months. All-cause mortality over 5 years was determined. Logistic regression analysis tested the associations between the cytokines' trajectories and mortality over 5 years, adjusted for covariates (age, sex, education, body mass index, lower extremity physical activities of daily living, and Charlson comorbidity index). High levels of IL-6 and sTNFα-R1 at baseline with small or no decline at 2 months were associated with higher odds of 5-year mortality compared with those with lower levels at baseline and greater decline at 2 months after adjustment for age, and other potential confounders (OR = 4.71, p = 0.01 for IL-6; OR = 15.03, p = 0.002 for sTNFα-R1). Similar results that failed to reach significance were found for IL-1RA (OR = 2.40, p = 0.18). Those with higher levels of cytokines at baseline with greater decline did not have significantly greater mortality than the reference group, those with lower levels at baseline and greater decline. Persistent elevation of plasma IL-6 and sTNFα-R1 levels within the first 2 months after hospital admission in patients with hip fracture is associated with higher 5-year mortality. These patients may benefit from enhanced care and earlier intensive interventions to reduce the risk of death.
