Nailing precision: a systematic review and meta-analysis of randomized controlled trials comparing piriformis and trochanteric entry points for femoral antegrade nailing.

INTRODUCTION: Entry point selection, a crucial aspect of femoral antegrade nailing, can impact nail fit and consequently fracture reduction. In adults, the standard entry portals used are the piriformis fossa and the tip of the greater trochanter. Previous systematic reviews comparing the two techniques have not been limited to Randomized Controlled Trials (RCTs) and have not consistently included the same available RCTs. MATERIALS AND METHODS: A systematic search of comparative studies regarding entry portal selection in femoral antegrade nailing was conducted on seven databases. Only Prospective RCTs comparing trochanteric and piriformis entry in the management of trochanteric or diaphyseal femur fractures were eligible for inclusion. RESULTS: Ultimately, only 6 RCTs were found eligible for inclusion. Five of the six included studies reported on operative time. The resulting mean difference (MD) illustrated a significant decrease in operative time by approximately 21.26 min (95% CI - 28.60 to - 13.92, p < 0.001) using trochanteric entry. Fluoroscopy exposure was reported on by four studies, however, only two studies were included in the analysis due to different reporting methods. Trochanteric entry used significantly less fluoroscopy than piriformis entry (MD -50.33 s, 95% CI - 84.441 to - 16.22, p = 0. 004). No significant difference in malalignment rates, delayed union rates, nonunion rates, pain scores, or complication rates was found. CONCLUSION: The significant differences found in operating time and fluoroscopy time align with those in other studies. While we were not able to pool the data on functional outcome scores, none of the included studies found a significant difference in scores by their last follow-up. Both approaches demonstrate comparable functional outcomes and safety profiles, indicating the choice of entry point should be at the discretion of the surgeon based on technique familiarity and fracture characteristics.

Operative Treatment of a Patient with a Pathological Fracture through a Large Non-ossifying Fibroma: A Case Report.

Introduction: Non-ossifying fibroma (NOF) is a common benign fibrogenic bone lesion commonly found in the metaphysis of long bones. While small NOFs are typically asymptomatic and left untreated, large NOFs are often associated with pathologic fractures that can be treated conservatively or operatively. To our knowledge, the NOF presented in this case report is one of the largest reported in the literature. Case Report: We present a case of a 12-year-old Hispanic female who presented to our institution after falling off a horse and landing on her right leg and wrist. Radiographs revealed a right distal femur fracture through an unusually large lytic bone lesion. The patient was treated with curettage, grafting, open reduction, and internal fixation, given the unstable and pathological nature of the fracture. Conclusion: This case substantiates the literature that large fractures through a NOF can be appropriately managed operatively. However, orthopedic surgeons should be aware of the risks of surgery, including infection, when considering operative management of patients who present with large unstable pathologic fractures through a NOF.

Orthopedic surgeon-scientist representation is low among National Institutes of Health grants for rotator cuff research.

Background: The purpose of this study is to characterize National Institutes of Health (NIH) funding for rotator cuff research and evaluate the impact of orthopedic surgeons on this portfolio. Methods: The NIH's Research Portfolio Online Reporting Tools Expenditures and Results database was queried for "rotator cuff repair" or "rotator cuff tear" from the 2011 to 2021 fiscal years. Compound annual growth rates were calculated and grants were categorized by basic, clinical, or translational research. Funding totals were compared by Principal Investigator (PI) and grant characteristics. Results: A total of 52 grants were awarded to 38 PIs between 2011 and 2021, totaling $40,156,859. Annual NIH funding for rotator cuff tear and rotator cuff repair increased by a Compound annual growth rate of 11.0% from 2011 to 2021, compared to 3.4% for the total NIH budget. Orthopedic surgeon-scientists received $9,208,212 (22.9%), most commonly through R01 (80.5%) and K08 (7.1%) mechanisms. No significant difference in funding was found by PI sex (P = .332), degree (P = .460), academic rank (P = .118), or researcher type (P = .227). Professors had a higher h-index than associate and assistant professors (P = .001). Orthopedic surgeon-scientists had a higher h-index (mean 36.3 ± 9.4) compared to clinician-scientists (mean 8.0 ± 1.4) and research-scientists (35.5 ± 40.7) (P = .044). Clinical topics receiving the highest funding were rehabilitation (23.9%), diagnosis, (22.3%) and surgical technique (14.8%). Orthopedic surgeon-scientists acquired funding for diagnosis (57.1%), rehabilitation (17.0%), and surgical technique (14.5%). Discussion: While NIH funding for rotator cuff research is growing, orthopedic surgeon representation is low. Future studies should evaluate barriers to obtaining funding for orthopedic surgeon-scientists.

The Impact of the City of Miami's Decision to Revoke Electric Scooter Company Permits on Orthopedic Trauma at a Level I Trauma Center.

BACKGROUND: Since the introduction of electric-scooter (e-scooter) mobile applications, there has been a marked increase in e-scooter-related injury. On January 19, 2022, the City of Miami revoked permits to five major mobile applications for violation of safety protocols. OBJECTIVES: The purpose of our study was to assess the effects of this notice on the orthopedic patients seen at our corresponding Level I trauma center. METHODS: Institutional Review Board approval was obtained for this study. A retrospective chart review was performed including all patients with orthopedic injuries at our Level I trauma center between July 19, 2021 and July 19, 2022. These dates include 6 months prior to and after the major e-scooter operators ceased use in Miami. SPSS statistical software version 28.0.0 (SPSS, IBM, Armonk, NY) was utilized for all statistical analysis. RESULTS: There were 2558 patients in the prenotice cohort, and 2492 patients in the postnotice cohort. After the notice, there was a significant decrease in the number of patients that presented to our institution due to injuries caused by e-scooters (2.8% vs. 1.8% patients; p = 0.021). Patients with injuries caused by e-scooters had a significantly lower age (38 vs. 42, respectively; p = 0.034) and were more likely to be male (79.3% vs. 67.4% male, respectively; p = 0.007) than patients with other orthopedic injuries. CONCLUSION: This study demonstrates that the 2022 notice revoking the major mobile application operators from the City of Miami resulted in a significant decrease in the number of orthopedic cases due to e-scooter-related injury at the corresponding Level I trauma center.

The performance of ChatGPT on orthopaedic in-service training exams: A comparative study of the GPT-3.5 turbo and GPT-4 models in orthopaedic education.

Introduction: The rapid advancement of artificial intelligence (AI), particularly the development of Large Language Models (LLMs) such as Generative Pretrained Transformers (GPTs), has revolutionized numerous fields. The purpose of this study is to investigate the application of LLMs within the realm of orthopaedic in training examinations. Methods: Questions from the 2020-2022 Orthopaedic In-Service Training Exams (OITEs) were given to OpenAI's GPT-3.5 Turbo and GPT-4 LLMs, using a zero-shot inference approach. Each model was given a multiple-choice question, without prior exposure to similar queries, and their generated responses were compared to the correct answer within each OITE. The models were evaluated on overall accuracy, performance on questions with and without media, and performance on first- and higher-order questions. Results: The GPT-4 model outperformed the GPT-3.5 Turbo model across all years and question categories (2022: 67.63% vs. 50.24%; 2021: 58.69% vs. 47.42%; 2020: 59.53% vs. 46.51%). Both models showcased better performance with questions devoid of associated media, with GPT-4 attaining accuracies of 68.80%, 65.14%, and 68.22% for 2022, 2021, and 2020, respectively. GPT-4 outscored GPT-3.5 Turbo on first-order questions across all years (2022: 63.83% vs. 38.30%; 2021: 57.45% vs. 50.00%; 2020: 65.74% vs. 53.70%). GPT-4 also outscored GPT-3.5 Turbo on higher-order questions across all years (2022: 68.75% vs. 53.75%; 2021: 59.66% vs. 45.38%; 2020: 53.27% vs. 39.25%). Discussion: GPT-4 showed improved performance compared to GPT-3.5 Turbo in all tested categories. The results reflect the potential and limitations of AI in orthopaedics. GPT-4's performance is comparable to a second-to-third-year resident and GPT-3.5 Turbo's performance is comparable to a first-year resident, suggesting the application of current LLMs can neither pass the OITE nor substitute orthopaedic training. This study sets a precedent for future endeavors integrating GPT models into orthopaedic education and underlines the necessity for specialized training of these models for specific medical domains.

Miscoding in the Nationwide Inpatient Sample Database Raises Questions About Validity for Arthroplasty Research.

BACKGROUND: The use of administrative databases in arthroplasty research has increased over the past decade. The Nationwide Inpatient Sample (NIS) is one of the first and most frequently used. Despite many published articles using this dataset, there exists no standardization resource accounting for the potential of biased results. The purpose of our study was to assess the amount of discordant data between clinically relevant variables and propose a standard for using this database in primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS: An initial set of patients undergoing total joint arthroplasty were identified from the NIS between 2016 and 2019 using the International Classification of Diseases, 10th Revision, Procedure Coding System. All records with THA and TKA in any of the procedure variables (PR1-PR20) were included. A total of 63 relevant and consistent variables were selected for individual comparison including diagnosis-related group (1), elective (1), procedure codes (20), day of main procedure (1), and diagnosis codes (40). Descriptive statistics were used. A total of 3,562,819 patients were included in the initial set. RESULTS: Using diagnosis-related groups, 5.3% were revision surgeries, 4.7% were not elective, 2.3% did not have THA or TKA as their primary procedure for hospitalization, and 2.9% of THA and 9.7% of TKA were bilateral. A total of 6.2% of the surgeries were done day(s) before or after admission, and 10.8% of THA and 6.3% of TKA were missing an orthopedic diagnosis for admission. Many had multiple orthopedic diagnoses for admission, 3.2% of THA and 0.7% of TKA. Overall miscoding was 23.3%. CONCLUSIONS: Using the NIS without standardized data processing to study elective, unilateral, primary THA and TKA introduces major bias. A logical and stepwise approach to curate the data before analysis is proposed to improve research quality when using this database in hip and knee arthroplasty studies.

Subtrochanteric nonunion after intramedullary nailing due to pathological fracture: proximal femoral replacement as a salvage approach.

PURPOSE: To assess proximal femoral replacement as a treatment solution for nonunion of pathologic subtrochanteric fractures after cephalomedullary nailing in patients with pathological fracture and previously irradiated bone. METHODS: Retrospective review of five patients with pathological subtrochanteric femoral fractures that were treated with cephalomedullary nailing and developed a nonunion, which was revised with conversion to a proximal endoprosthetic replacement. RESULTS: All five patients had previously been treated with radiation. One patient had the latest follow-up at 2 months postoperatively. At that time, the patient was walking with a walker for assistance, with no evidence of hardware failure or loosening on imaging. The remaining four patients had the latest follow-up ranging from 9 to 20 months after surgery. At their latest follow-up, three of the four patients were ambulatory with no pain, using only a cane for assistance with longer distances. The other patient demonstrated pain in his affected thigh, utilizing a walker for assistance with ambulation at latest follow-up, but not requiring further surgical interventions. There were no hardware failures or implant loosening through the follow-up period. None of the patients required revision, and there were no postoperative complications observed at their last follow-up. CONCLUSIONS: In patients with pathological fractures in the subtrochanteric region that is treated with cephalomedullary nailing and developed a nonunion, treatment with conversion to a proximal femoral replacement with a mega prosthesis is a valuable treatment with good functional results and low risk for complications. LEVEL OF EVIDENCE: Therapeutic level IV.

Research trends in testosterone deficiency and management: A bibliometric analysis approach to quality improvement in urology resident education.

INTRODUCTION: Previous work has demonstrated a deficiency in urology resident education when it comes to andrology and male infertility. We analyzed the top 100 most frequently cited and influential articles published on testosterone deficiency and its associated therapy, allowing trainees and clinicians to review and understand the characteristics of impactful literature for self-directed learning purposes. METHODS: The ISI Web of Knowledge database was used to find articles on testosterone deficiency, hypogonadism, and replacement therapies. Relevant, peer-reviewed, English articles were included. Article details, including title, citation count, publication year, and more, were gathered. Articles were classified based on content (e.g. clinical outcomes, anatomy, and trends) using defined criteria. RESULTS: The top 300 most cited were reviewed with 100 included. The most cited article had 774 citations, averaging 234 in the top 100. Publication years had peaks in 2003-2004 and 2006-2007. The US led in publications (56), followed by England (16), Germany (14), and Italy (13). Common affiliations included US Department of Veteran Affairs, Veterans Health Administration, RIC Research Education Clinical Center, and University of California System. Articles were categorized as LOE 2 (47), LOE 1 (22), and LOE 5 (21). Articles focused on clinical outcomes (71.7%), anatomy/biomechanics/physiology (14.1%), clinical guidelines (8.1%), and screening (4%). The "Journal of Clinical Endocrinology & Metabolism" published 26 of the top 100 cited articles. CONCLUSIONS: This analysis highlights influential articles regarding testosterone deficiency and management. The discussed articles have significant clinical and therapeutic implications for the practicing urologist which may bolster deficits in current resident education.

Lower Perioperative Complication Rates and Shorter Lengths of Hospital Stay Associated With Technology-Assisted Total Knee Arthroplasty Versus Conventional Instrumentation in Primary Total Knee Arthroplasty.

BACKGROUND: The use of technology allows increased precision in component positioning in total knee arthroplasty (TKA). The objectives of this study were to compare (1) perioperative complications and (2) resource utilization between robotic-assisted (RA) and computer-navigated (CN) versus conventional (CI) TKA. METHODS: A retrospective cohort study was performed using a national database to identify patients undergoing unilateral, primary elective TKA from January 2016 to December 2019. A total of 2,174,685 patients were identified and included RA (69,445), CN (112,225), or CI (1,993,015) TKA. Demographics, complications, lengths of stay, dispositions, and costs were compared between the cohorts. Binary logistic regression analysis was performed. RESULTS: The RA TKA cohort had lower rates of intraoperative fracture (0.05 versus 0.08%, P < .05), respiratory complications (0.6 versus 1.1%, P < .05), renal failure (1.3 versus 1.7%, P < .05), delirium (0.1 versus 0.2%, P < .05), gastrointestinal complications (0.04 versus 0.09%, P < .05), postoperative anemia (8.9 versus 13.9%, P < .05), blood transfusion (0.4 versus 0.9%, P < .05), pulmonary embolism, and deep vein thrombosis (0.1 versus 0.2%, P < .05), and mortality (0.01 versus 0.02%, P < .05) compared to conventional TKA, though the cohort did have higher rates of myocardial infarction (0.09 versus 0.07%, P < .05). The CN cohort had lower rates of myocardial infarction (0.02 versus 0.07%, P < .05), respiratory complications (0.8 versus 1.1%, P < .05), renal failure (1.5 versus 1.7%, P < .05), blood transfusion (0.8 versus 0.9%, P < .05), pulmonary embolism (0.08 versus 0.2%, P < .05), and deep vein thrombosis (0.2 versus 0.2%, P < .05) over CI TKA. Total cost was increased in RA (16,190 versus $15,133, P < .05) and CN (17,448 versus $15,133, P < .05). However, the length of hospital stay was decreased in both RA (1.8 versus 2.2 days, P < .05) and CN (2.1 versus 2.2 days, P < .05). CONCLUSIONS: Technology-assisted TKA was associated with lower perioperative complication rates and faster recovery.

Varying Complication Rates and Increased Costs in Technology-Assisted Total Hip Arthroplasty Versus Conventional Instrumentation in 1,372,300 Primary Total Hips.

BACKGROUND: The use of technology allows surgeons increased precision in component positioning in total hip arthroplasty (THA). The objective of this study was to compare (1) perioperative complications and (2) resource utilizations between robotic-assisted (RA) and computer-navigated (CN) versus conventional instrumenttaion (CI) THA. METHODS: A retrospective cohort study was performed using a large national database to identify patients undergoing unilateral, primary elective THA from January 1, 2016 to December 31, 2019 using RA, CN, or CI. There were 1,372,300 total patients identified and included RA (29,735), CN (28,480), and CI (1,314,085) THA. Demographics, complications, lengths of stay, dispositions, and costs were compared between the cohorts. Binary logistic regression analyses were performed. RESULTS: The use of RA THA led to lower rates of intraoperative fracture (0.22% versus 0.39%), delirium (0.1% versus 0.2%), postoperative anemia (14.4% versus 16.7%), higher myocardial infarction (0.13% versus 0.08%), renal failure (1.7% versus 1.6%), blood transfusion (2.0% versus 1.9%), and wound dehiscence (0.02% versus 0.01%) compared to CI THA. The use of CN led to lower rates of respiratory complication (0.5% versus 0.8%), renal failure (1.1% versus 1.6%), blood transfusion (1.3% versus 1.9%), and pulmonary embolism (0.02% versus 0.1%) compared to CI THA. Total costs were increased in RA ($17,729 versus $15,977) and CN ($22,529 versus $15,977). Lengths of hospital stay were decreased in RA (1.8 versus 1.9 days) and CN (1.7 versus 1.9 days). CONCLUSIONS: Perioperative complication rates vary in technology-assisted THA, with higher rates in RA THA and lower rates in CN THA, relative to CI THA. Both RA THA and CN THA were associated with more costs, shorter postoperative hospital stays, and higher rates of discharge home compared to CI THA.

The Use of Blocking Wires in Fibular Intramedullary Nailing of an Ankle Fracture with Hardware Failure: A Case Report.

A 24-year-old male, with a body mass index (BMI) of 31.7 and a previous open reduction and internal fixation (ORIF) of the left ankle seven years ago, presented to the emergency department with a peri-implant, comminuted fibula fracture with broken hardware and syndesmotic injury. The nature of the revision surgery made proper guidewire placement during fibular nailing difficult. Blocking wires assisted in ensuring proper guidewire placement. The patient was successfully managed with revision ORIF, fibular nailing, and syndesmotic fixation. Blocking wires are a helpful tool for achieving proper fracture alignment and stability during intramedullary nailing procedures and may be considered in fibular nailing situations.

The impacts of anxiety and depression on outcomes in orthopaedic trauma surgery: a narrative review.

Introduction: The impact of anxiety and depression on outcomes in orthopaedic trauma surgery is a topic of growing research interest. Patients and methods: Orthopaedic trauma patients often experience high rates of psychiatric disorders, with anxiety and depression being the most prevalent. Mental health disorders have been shown to increase the risk of negative surgical outcomes and morbidity. This narrative review seeks to summarize the current literature surrounding the impacts of anxiety and depression on orthopaedic trauma surgery outcomes. Discussion: There is a bidirectional relationship between chronic pain and mental health disorders, involving overlapping brain regions and neurotransmitter pathways. Anxiety and depression have been identified as predictors of negative surgical outcomes in orthopaedic trauma patients. Screening tools like the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Screener-7 (GAD-7), and Medical Outcomes Study 36-item Short Form (SF-36) can assess mental health status and help tailor interventions. Psychological distress, chronic pain, and traumatic limb amputation are factors that contribute to adverse mental health outcomes in orthopaedic trauma patients. Opioid use for pain management is common in orthopaedic surgery, but it can worsen symptoms of depression and lead to dependency. Non-opioid pain management strategies may improve postoperative outcomes by reducing the impact of opioid-exacerbated depression. Conclusion: Mental health interventions, both preoperative and postoperative, are crucial in optimizing surgical outcomes and improving patient quality of life. Multidisciplinary approaches that address both physical and mental health are recommended for orthopaedic trauma patients. Further research is needed to develop effective interventions for improving mental health outcomes in this patient population.

Safe Zones and Trajectory of Femoral Pin Placement in Robotic Total Knee Arthroplasty.

Background: Robotic-assisted total knee arthroplasty may result in array pin-related complications. Lack of knowledge on ideal pin placement results in varied insertion sites and trajectory, with unknown risks to surrounding neurovascular structures. Methods: This study included 10 lower-extremity magnetic resonance images. Images were subdivided into 6 zones of study. Zones consisted of a correlating axial image with femoral pin placement replicated by drawing a line angled 45° from the anterior to posterior reference in the anteromedial to posterolateral femoral quadrants. The distances from the pin paths to the neurovascular structures were measured. Results: Zone 2C demonstrated femoral pin trajectory an average of 14 mm from the femoral artery/vein. In Zone 2B, proximity increased to an average of 30 mm to the femoral artery and 29 mm to the femoral vein. At Zone 1A, the popliteal artery and vein were on average 22 mm from the femoral pin, while the common peroneal nerve was an average of 21 mm. Placing pins in Zone 1A poses a high risk of injury to the genicular arteries. Women demonstrated greater proximity to neurovascular structures than men in 66% of the sites (P < .05). Conclusions: This classification system for safe zones and trajectory of femoral pin placement in robotic-assisted total knee arthroplasty demonstrates that proximally, the profunda femoris and femoral artery/vein are at risk of injury, while distally, the genicular arteries, common peroneal nerve, and popliteal artery/vein are at risk. Caution should be exercised if femoral pins are inserted with an angle less than 45°, especially in women.

Trochanteric Bolt Failure in a Modular Femoral Revision System.

With the incidence of primary total hip arthroplasty continuing to rise in the United States, the innovation behind improving current total hip arthroplasty systems inevitably grows with it-each new design potentially ushering in new flaws. We report a case of screw failure with the Arcos Modular Femoral Revision System-Trochanteric Bolt and Claw Technique in a 74-year-old male patient. The patient presented to the investigator's clinic for their 20-month follow-up evaluation of their complex right hip revision. Radiographs revealed failure of the screw attaching the claw plate to the stem resulting in dislodgement and relocation of the screw within the intra-articular cavity. The patient elected for nonsurgical management and will continue to be monitored. Consent by the patient involved in this case report was obtained.

Subacromial balloon spacers for the treatment of irreparable rotator cuff tears: a review.

Massive irreparable rotator cuff tears (RCTs) are a commonly encountered orthopedic condition that can be difficult to treat. Several techniques have been described to manage these tears, with the implantable subacromial balloon spacer being one of the most recent. The device, which has only been approved for clinical use in the United States since 2021, functions by resisting the superior humeral head migration seen in the setting of massive RCTs and restoring normal shoulder biomechanics, as corroborated by cadaveric studies. However, results regarding clinical outcomes have been mixed to date, and further high-quality studies are needed to define the optimal use of the subacromial balloon spacer in the treatment of massive irreparable RCTs.

Influential literature regarding proximal junctional kyphosis: A bibliometric review.

Study design: Retrospective review. Objective: This bibliometric review summarizes the publication trends and critical information about the most cited Proximal Junction Kyphosis (PJK) articles. Background: Data: Proximal junctional kyphosis is frequently diagnosed after spinal fusion surgery. However, there continues to be heavy debate regarding the definition, incidence, risk factors, and treatment of this disorder. Methods: Nine hundred eleven articles were found when searching The Web of Science database with the keywords "Proximal junctional kyphosis" and "proximal junctional failure." The 200 top-cited articles were reviewed and screened to ensure PJK was discussed. The articles were filtered based on the highest to lowest number of citations, and the top 50 articles were chosen. Inclusion criteria included articles that contained a discussion of PJK and outcomes after surgery. Exclusion criteria included articles without mentioning PJK, or that studied non-human subjects. The 50 most cited articles were sorted by level of evidence and their classification for analysis. Results: The 50 most cited articles in this study were published a total of 6056 times. These articles were cited 71-413 times in the literature, with publications from 1994 to 2018. Most of the top 50 articles (64%) were published in the USA. Specifically, HSS and Washington University are the institutions with the most contributions to the publication of the most cited articles on PJK (n = 16). Lenke was the author that contributed to most publications in the top 50 articles on PJK. Conclusion: This study provides a framework for the most cited articles published on PJK. Most articles on this topic were in the category of clinical outcomes (36%) and were of a level of evidence III (46%). Most of the top-cited articles came from the journal Spine (68%) and were published in the USA (64%). These top-cited papers are essential to understanding this critical trending topic in spine surgery. Level of evidence: III.

The Rate of Medial Ulnar Collateral Ligament Repair Is Increasing While Reconstruction Remains the Most Common Procedure Overall Among Early-Career Orthopaedic Surgeons.

Purpose: To determine the practice patterns and complication rates in medial ulnar collateral ligament (MUCL) repair versus reconstruction procedures performed by early-career orthopaedic surgeons each year between 2010 and 2020, stratified by fellowship training and concomitant procedures performed, during their 6-month American Board of Orthopaedic Surgery (ABOS) Case List collection period. Methods: The ABOS database was queried for MUCL reconstruction and MUCL repair procedures reported by ABOS Part II Oral Examination examinees from 2010 to 2020. Surgeon fellowship training background, patient demographics, procedural diagnosis codes, complications, and concomitant procedures were recorded for each case. Differences between overall procedure rates and the associated complications reported were examined. Data regarding the specific injury pathology and other patient-specific characteristics for each case were not available. Results: In total, 187 primary procedures performed to address isolated MUCL injuries were reported. Of those, 83% (n = 155) were reconstructions and 17% (n = 32) were repairs. The annual percentage of MUCL repair increased from 10% (1/10) in 2010 to 38% (8/21) in 2020 (linear regression; R2 = 0.56, P < .05). The cumulative complication rate for MUCL reconstruction (11.6%) was significantly lower than for MUCL repair (25%) from 2010 to 2020 (P < .05). This remained true among subsets of cases from Orthopaedic Sports Medicine, Shoulder & Elbow, and or Hand Surgery fellowship-trained examinees, although only statistically significant in the Hand Surgery subset. Reported complication rates were not significantly different among cases in which concurrent ulnar nerve neuroplasty and/or transposition or concurrent elbow arthroscopy were performed. Conclusions: Among cases reported by ABOS Part II Oral Examination examinees from 2010 to 2020, there was an increasing rate of MUCL repair whereas MUCL reconstruction remained more common overall. Interestingly, the overall complication rates were significantly lower for MUCL reconstruction than for MUCL repair both in isolation and when concurrent procedures were performed. Level of Evidence: Level III, retrospective cohort study.

Orthopedic approaches for bone sarcoma: A bibliometric review of the 50 most cited papers.

Background: Curative treatment of bone sarcoma is primarily based on operative management. The Orthopedic Oncology approach towards this disease has evolved greatly to the breakthrough in systemic treatment options as well as unique implant designs favoring limb salvage over amputations. The purpose of this study was to perform a bibliometric analysis of the top 50 most cited papers related to the orthopedic the approach to bone sarcomas. Methods: We queried the ISI Web of Knowledge database in July 2022. Keywords utilized were: ""Bone Sarcoma" OR "Osteosarcoma" OR "Ewing Sarcoma" OR "Chondrosarcoma" OR "Chordoma". The top 50 articles pertaining to the orthopedic approach to bone sarcoma were included for analysis and included manuscript title, authors, citation count, journal and publication year. Results: The mean number of citations are 187.06 (Range 125-400; SD 67.83). The average citations per year is 10.03 (Range 47.86-3.43; SD 8.05). Many articles were published from 2000 to 2009 (n = 20) and 1990-1999 (n = 13). The majority of the articles were published by institutions within the United States (n = 32). The most common level of evidence was level IV (n = 37). Majority of the articles focused on treatment outcome (n = 22). Conclusion: This study offers a comprehensive review of the most cited literature regarding orthopedic approaches to bony sarcomas. Modern treatment approaches for bone sarcoma has resulted in an increased focus within the literature on achieving disease free survival wide tissue margins. Understanding the trends of available studies allows for physicians and researchers to target and innovate future areas of study.

Most patient education materials on shoulder conditions from the American Academy of Orthopaedic Surgeons exceed recommended readability levels.

Background: A growing number of patients use the internet to learn about their conditions and management options, but there may exist a disconnect between the readability of online education materials and a patient's health literacy. This issue is of particular relevance for shoulder conditions, where even with traumatic injuries (eg, clavicle fracture, shoulder dislocation), treatment is discretionary, directed primarily at quality of life, and therefore highly preference-sensitive.The purpose of this study was to utilize multiple readability algorithms to calculate the readability of the American Academy of Orthopaedic Surgeons (AAOS) patient education materials pertaining to diseases and conditions of the shoulder. Methods: Online patient education articles from the AAOS pertaining to diseases and conditions of the shoulder were reviewed. The articles were modified for analysis using Readability Pro and readability scores were computed using the following 9 algorithms: Flesch-Kincaid Grade Level, Flesch Reading Ease, Gunning Fog Index, Coleman-Liau Index, Simple Measure of the Gobbledygook Index (SMOG), Automated Readability Index, FORCAST, and New Dale and Chall Index. A list of suggested word changes to improve the readability of included articles was compiled from Readable Pro. The average number of illustrations (images and/or videos) included per article was documented. Results: Twenty-eight articles were included for analysis. For each of the algorithms studied, the average scores were as follows: Flesch Kincaid Grade Level was 8.8 ± .8 [range, 7.2-10.2]; recommended score: ≤ 8.0, Flesch Reading Ease 54.3 ± 5.3 [range, 45.3-64.1]; recommended score: ≥ 60, Gunning Fog 10.8 ± 1.2 [range, 8.3-13.1]; recommended score: ≤ 8.0, Coleman-Liau 11.2 ± .9 [range, 9.2-12.9]; recommended score: ≤8.0, SMOG index 11.4 ± .8 [range, 9.2-12.9]; recommended score: ≤ 8.0 , Automated Readability Index 8.4 ± .8 [range, 6.9-10.0]; recommended score: ≤ 8.0, FORCAST 11.2 ± .4 [range, 10.2-12.0]; recommended score: ≤ 9.0, and New Dale and Chall Index 5.8 ± .5 [range, 4.9-7.2 recommended score: ≤ 6.0-6.9]. The average number of illustrations per article was 4.5 ± 3.1 [range, 1-14]. Conclusion: The readability of most patient education materials from the AAOS pertaining to diseases and conditions of the shoulder is higher than recommended across a variety of algorithms. Efforts to revise the readability of online education materials are important to facilitate shared decision-making, particularly in practice settings where most decisions are preference-sensitive.

The Relative Citation Ratio: Evaluating a New Measure of Scientific Influence Among Academic Sports Medicine Surgeons.

Background: Objective measures of research influence are being increasingly utilized to evaluate and compare academic faculty. However, traditional bibliometrics, such as the Hirsch index and article citation count, are biased by time-dependent factors and are limited by a lack of field normalization. The relative citation ratio (RCR) is a new field- and time-normalized article-level metric developed by the National Institutes of Health (NIH). Purpose/Hypothesis: The purpose of this study was to evaluate the RCR among fellowship-trained academic sports medicine surgeons and to analyze physician factors associated with RCR values. We hypothesized that the mean RCR score for fellowship-trained academic sports medicine surgery faculty will fall above the NIH standard. Study Design: Cross-sectional study. Methods: A retrospective data analysis was performed using the iCite database for all fellowship-trained sports medicine surgery faculty associated with Accreditation Council for Graduate Medical Education-accredited orthopaedic surgery residency programs in December 2021. In eligible faculty, the mean RCR, weighted RCR, and total publication count were compared by sex, career duration, academic rank, and presence of additional degrees. A mean RCR value of 1.0 is the NIH-funded field-normalized standard. The data herein are presented as the median and interquartile range, in addition to the mean and standard deviation, to account for outliers of the mean and weighted RCR scores. Results: A total of 624 fellowship-trained sports medicine surgery faculty members from 160 orthopaedic surgery residency programs were included in the analysis. Overall, faculty produced impactful research, with a median RCR of 1.6 (interquartile range, 1.0-2.2) and a median weighted RCR of 19.3 (interquartile range, 5.1-69.3). Advanced academic rank and career longevity were associated with increased weighted RCR and total publication count. All subgroups analyzed had an RCR value >1.0. Conclusion: Study findings indicate that fellowship-trained academic sports medicine surgery faculty are highly productive and produce impactful research, as evidenced by the high median RCR value relative to the benchmark NIH RCR value of 1.0.
