Background: The Latarjet procedure is a common bony augmentation procedure for anterior shoulder instability. Historically, screw fixation is used to secure the coracoid graft to the anterior glenoid surface; however, malpositioning of the graft leads to oblique screw insertion that contributes to complications. Suture buttons (SBs) are a more recent fixation technique that have not been studied alongside standard screw fixation in the context of biomechanical models of angulated fixation. This study aims to compare the biomechanical strength of single and double, screw and SB fixation at various levels of angulation. Methods: Testing was performed using polyurethane models from Sawbones. The graft piece was secured with screw fixation (Arthrex, Naples, FL, USA) or suspensory button (ABS Tightrope, Arthrex, Naples, FL, USA). Single or double constructs of screws and SBs were affixed at 0°, 15°, and 30° angles to the face of the glenoid component. An aluminum testing jig held the samples securely while a materials testing system applied loads. Five constructs were used for each condition and assessed load to failure testing. Results: For single fixation constructs, suspensory buttons were 60% stronger than screws at 0° (P

Background: Biceps tenodesis is a common treatment for pathologies involving the long head of the biceps brachii. Given variations in surgical approach, focus has been placed on the location of the tenodesis to maintain appropriate length-tension relationship. The purpose of this study is to assess for variations in the tunnel placement in subpectoral biceps tenodesis procedures and correlation of tunnel position with patient-reported outcomes. Methods: This is a retrospective case series of outcomes as a function of tunnel location with open subpectoralis biceps tenodesis. The location of the biceps tenodesis tunnel was measured on postoperative Grashey radiographs. Correlation between the tenodesis tunnel and postoperative American Shoulder and Elbow Surgeons (ASES) score and Visual Analog Scale (VAS) was assessed. Results: 31 patients were included in the study with an average follow-up of 17 months. The overall tunnel position from the superior edge of the greater tuberosity ranged from 4.20 cm to 12.61 cm, with an average of 7.46 cm. Final ASES score and VAS were 84.5 and 1.2, respectively. There was only weak correlation between both ASES score and tunnel position (r = −0.12) and VAS and tunnel position (r = −0.23). Discussion: Subpectoralis biceps tenodesis continues to be a viable treatment option for biceps and superior labral pathology. There remains no consensus on tenodesis location, and this study found no significant difference between tunnel location and patient-reported outcomes. Therefore, it is likely that a range of tenodesis locations exists in which favorable clinical results are achieved, explaining the numerous recommendations on tunnel placement.

Background:. Few evidence-based suggestions are available to help applicants and mentors improve reapplication outcomes. We sought to provide program directors' (PDs) perspectives on actionable steps to improve reapplicants' chances for a match. Methods:. The PDs were asked to rank positions unmatched applicants can pursue, steps these applicants can take for the next application cycle, and reasons why reapplicants do not match. Results:. Responses from 66 of 123 PDs were received (53.6% response rate). Obtaining new recommendation letters and rotating with orthopaedics were the highest 20 ranked steps unmatched applicants can take. No curriculum vitae (CV) improvement, poor interview, and poor letters of recommendation were the most important reasons hindering applicants from matching when reapplying. Conclusions:. Steps reapplicants could prioritize include obtaining new recommendation letters, rotating in orthopaedics, and producing new research items. CV strengthening and improving interview skills address the 2 main reasons why unmatched applicants failed in subsequent attempts. Level of Evidence:. Level IV

Background: Glenohumeral joint instability and dislocation are common orthopedic pathologies that can produce osseous humeral head defects such as Hill-Sachs (HS) or Reverse Hill-Sachs (RHS) lesions. Numerous reconstruction techniques have been reported in the literature, including remplissage, disimpaction, and allograft reconstruction. No group has previously assessed the outcomes of allograft reconstruction for RHS lesions, nor compared the outcomes of allograft reconstruction for HS and RHS lesions. In this study, we aim to provide a comprehensive assessment of osteochondral allograft reconstruction for the distinct pathologies of RHS lesions and HS lesions by comparing postreconstruction patient-reported outcomes, complications, and radiographic assessments for each lesion. Methods: Using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, a systematic review was performed to identify and include studies that reported patient outcomes after the use of osteochondral allografts in the reconstruction of HS or RHS lesions of the humeral head. A comprehensive search of the Google Scholar, PubMed, and Embase databases was conducted with the key terms “allograft,” “Hill-Sachs,” and “reverse Hill-Sachs.” Results: Eight studies, with a total of 84 patients, were included for review. Of the 84 allograft-treated patients, there were 44 patients with HS lesions and 40 patients with RHS lesions. The average patient age was 27.3 years for HS lesions and 43.0 years for RHS lesions. Postoperative range of motion and average Constant-Murley score (87.9 for HS and 80.1 for RHS) appeared to be greater for those with HS lesions. In addition, 20.5% of HS patients experienced postoperative complications, whereas 42.5% of RHS patients had postoperative complications (P = .03). HS and RHS patients experienced similar proportions of graft resorption or collapse rate (22.7% for HS and 12.5% for RHS; P = .2). Conclusion: Patient-reported outcomes indicate that osteochondral allograft reconstruction for large RHS and HS lesions is an acceptable intervention. RHS patients had lower rates of graft resorption and collapse but worse postoperative range of motion and functional outcomes, although these differences were not statistically significant. HS patients experienced significantly fewer complications than those with RHS lesions.

Background: Rotator cuff tear (RCT) chronicity is an important factor in considering treatment options and outcomes for surgical repair. Many factors may contribute to delayed treatment, including timely access to care due to insurance status. The purpose of this study was to evaluate the relationship between the magnitude of RCT on presentation and insurance status. We hypothesize that publicly insured patients will have a greater incidence of chronic RCTs and shoulder pathology on initial presentation. Methods: Retrospective chart review of patients undergoing RCT repair at an academic tertiary care institution from 2005 to 2019. Demographic data, including age, race, sex, and insurance carrier, were collected. Insurance carriers were categorized into public (Medicare and Medicaid) or private insurance coverage. Individual magnetic resonance imagings were then reviewed by a board-certified musculoskeletal radiologist for supraspinatus (SS), infraspinatus (IS), subscapularis, and biceps tendon tears, as well as acromioclavicular arthritis. In addition, rotator cuff atrophy was evaluated by the scapular ratio. Univariate analysis of variance and logistic regression analyses were used to compare demographics and rotator cuff pathology between those with Medicaid and Medicare, as well as between publicly and privately insured patients. Results: Of the 492 patients in this study, 192 had private insurance, and 300 had public insurance (Medicaid: 50 and Medicare: 250). Insurance status was not found to be associated with differences in RCTs between Medicare and Medicaid patients. Those with Medicaid or Medicare (public), presented more frequently with SS or IS atrophy (SS atrophy, P = .002; IS atrophy, P = .039) than those with private insurance. However, after adjusting for age, no significant differences in rotator cuff tendon tear or atrophy frequencies were found between insurance groups. Conclusions: Patients with private and public insurance tend to present with similar chronicity and magnitude of RCTs. Insurance status does not appear to influence timely access to surgical care for patients with RCTs at an academic medical center.

Introduction:. Orthopaedic surgery is one of the most competitive and least diverse specialties in medicine. Affiliation of an orthopaedics with an allopathic medical school impacts research opportunities and early exposure to clinical orthopaedics. The purpose of this study is to examine the potential effect allopathic medical school affiliation has on orthopaedic surgery resident demographics and academic characteristics. Methods:. All 202 Accreditation Council for Graduate Medical Education (ACGME)-accredited orthopaedics programs were divided into 2 groups: Group 1 consisted of residency programs without an affiliated allopathic medical school, and Group 2 consisted of programs with an affiliated allopathic medical school. Affiliations were determined by cross-referencing the ACGME residency program list with the medical school list published by Association of American Medical Colleges (AAMC). Program and resident characteristics were then compiled using AAMC’s Residency Explorer including region, program setting, number of residents, and osteopathic recognition. Resident characteristics included race, gender, experiences (work, volunteer, and research), peer-reviewed publications, and US Medical Licensing Examination Step 1 scores. Results:. Of the 202 ACGME-accredited orthopaedics residencies, Group 1 had 61 (30.2%) programs, and Group 2 had 141 (69.8%) programs. Group 2 had larger programs (4.9 vs. 3.2 resident positions/year; p < 0.001) and 1.7 times the number of residency applicants (655.8 vs. 385.5; p < 0.001). Most Group 2 residents were allopathic medical school graduates, 95.5%, compared with 41.6% in Group 1. Group 1 had 57.0% osteopathic medical school graduates, compared with 2.9% in Group 2. There were 6.1% more White residents in Group 1 residencies (p = 0.025), and Group 2 residencies consisted of 3.5% more Black residents in relation to Group 1 (p = 0.03). Academic performance metrics were comparable between the 2 groups (p > 0.05). Conclusion:. This study demonstrated that candidates who successfully match into an orthopaedic surgery residency program achieve high academic performance, regardless of whether the program was affiliated with an allopathic medical school. Differences may be influenced by increased representation of minority faculty, greater demand for allopathic residents, or stronger emphasis on promotion of diversity in those residency programs.

Background: Tendon-to-bone (TtB) healing is essential for successful rotator cuff repair (RCR). This study aimed to investigate if caffeine intake impaired TtB healing in a rat RCR model. Methods: Seventy-two rats were randomized into a caffeinated group or a noncaffeinated group. Specimens received one week of oral caffeine solution or normal saline before RCR. All rats then underwent bilateral RCR. Caffeination or saline gavages continued until rats were sacrificed at 2, 4, and 8 weeks postoperatively. Load-to-failure (primary outcomes measure), maximum stress, and stiffness of the TtB interface were measured for one shoulder of each specimen. Six random shoulders from each group underwent histological assessment of TtB healing. Results: Load-to-failure and maximum stress of RCR did not appear to differ between groups at any time point. No difference in RCR stiffness was found between groups at 2 and 4 weeks; however, stiffness in the caffeinated group did appear to lower at 8 weeks (P = .04). Conclusion: Perioperative caffeine intake did not appear to affect load-to-failure strength of RCR in an animal model. Although our secondary outcome measures of maximum stress and stiffness also did not appear to be influenced by perioperative caffeine intake, there did appear to be a trend toward decreased RCR stiffness at 8 weeks postoperatively in specimens that received caffeine.

Background: Percutaneous fixation of proximal humeral fractures places the axillary nerve and posterior humeral circumflex artery at risk for injury. Safe operative zones for the axillary nerve are described based on external measurements from anatomic landmarks, but no study to date has incorporated advanced imaging to help guide surgical procedures in the region of the axillary neurovascular bundle (ANVB). We sought to define the location and trajectory of the ANVB in relation to osseous landmarks using magnetic resonance imaging (MRI) measurements. Methods: Retrospective review of 750 consecutive MRI studies was performed with 55 imaging studies meeting inclusion criteria for patient positioning, image alignment, and quality. Five measurements were performed including the distance from mid-lateral acromion to lateral ANVB, mid-lateral acromion to medial ANVB, greater tuberosity to lateral ANVB, vertical distance between inferior anatomic neck and lateral ANVB, and angle the ANVB crosses the humerus. Height, gender, and age were recorded. Analysis was performed using ANOVA and Pearson correlation tests. Results: The lateral ANVB was below the inferior articular margin of the humeral head by an average of 12.9 ± 3.9 mm and within a 22 mm window. It was an average of 57.4 ± 5.1 mm from the lateral mid-acromion, and 34.7 ± 4.3 mm below the greater tuberosity. The angle formed by the ANVB crossing the humerus averaged 19.5 ± 3.9 degrees upward from medial to lateral. Height and gender directly impacted measurements. Conclusions: The use of the inferior humeral head articular margin provides a radiographic landmark to aid intraoperative lateral ANVB assessment which may be helpful during percutaneous fracture fixation.

Background:. To maintain the integrity of the match, postinterview communication (PIC) from programs to applicants is monitored and discouraged. The most recent report on the prevalence of PIC in orthopaedics found that 64% of surveyed applicants in 2014 and 2015 had received some form of PIC during their match cycle. In July 2019, the American Orthopaedic Association’s Council of Orthopaedic Residency Directors (AOA/CORD) released a guideline recommending the elimination of all PIC in any form. The goal of this follow-up study was to determine the current prevalence of PIC with orthopaedic surgery applicants and assess the perspectives of medical students who recently applied for orthopaedic surgery residency positions. Methods:. A 35-question survey was e-mailed to all orthopaedic surgery residency applicants of 4 geographically diverse residency programs in postmatch March 2020. The survey was open for 1 month, and the responses were reported using descriptive statistics. Results:. Of the 229 respondents (21% response rate), 91 (39.7%) received PIC during the 2019 to 2020 residency match cycle. The program director was most commonly identified (80.2%) as the person who communicated with the applicants. At the interview day, 198 respondents (86.5%) were told that programs would not be contacting the applicants with PIC. However, over a quarter of respondents (25.3%) who received PIC answered that those programs contacted applicants after announcing they would not. Nearly half of the respondents (48.5%) agreed or strongly agreed that PIC causes added stress on applicants, and over half (52.9%) agreed or strongly agreed that all programs should stop participating in any form of PIC. Conclusions:. Although the prevalence of PIC seems to have decreased since the 2014 and 2015 match, there is still room for improvement toward eliminating PIC. The AOA/CORD position statement from July 2019 should be disseminated to all members of the residency selection team to ensure consistency from all programs. The primary limitation of this study was the 21% response rate. Level of Evidence:. Level IV (survey study)

Introduction:. Osteoporosis is a critical public health issue with substantial morbidity and healthcare costs. Resident education on osteoporosis is not standardized. Little is known about the barriers to osteoporosis treatment and the usefulness of educational programming from the perspective of orthopaedic residency program directors (PDs). Methods:. This study aims to evaluate the current state and perception of bone health education from the perspective of orthopaedic residency PDs. Therefore, a self-designed 29-question online survey was sent to 129 PDs in the United States to assess bone health education. The information, collected from August to October 2020, included program characteristics, participation in the American Orthopaedic Association’s Own the Bone (AOA/OTB) program or any fracture liaison service (FLS) program, availability of faculty, potential barriers, and educational resources. Data collection was performed anonymously with a 47% response rate. Results:. The results were compared between programs that used the AOA/OTB program (30%) or any FLS program (28%) (58% OTB or any FLS) vs. programs that did not have any program (42%). Subsequent subanalysis was performed comparing AOA/OTB vs. any FLS vs. no program. Programs that did not have any FLS were least likely to have a formal education syllabus (p = 0.01). When comparing clinical education of residents on bone health, 64% of programs without any system did not provide any formal clinical exposure such as a bone health clinic vs. assessment in patients with fracture compared with 24% of OTB programs and 44% of programs with any FLS (p = 0.02). When asked about desired resources, 47% would find a bone health rotation useful. Among all PDs, 60% support the concept of a 5-year AOA Council of Orthopaedic Residency Directors (CORD)/OTB osteoporosis curriculum. Discussion:. The key findings were that institutions including OTB or any FLS in their programs had better availability of specialty consultants, faculty, and a FLS coordinator.

Background:. The prosperous financial relationship between physicians and industry remains a highly scrutinized topic. Recently, a publicly available website was developed in conjunction with the U.S. Affordable Care Act to shed light on payments from industry to physicians with the goal of increasing transparency. The purpose of this study was to assess possible relationships between industry payments and orthopaedic surgeon gender, subspecialty training, and practice settings. Methods:. A retrospective analysis was performed using publicly available information from the Centers for Medicare & Medicaid Services (CMS) to identify the 25 orthopaedic surgeons with the highest compensation from each of the 10 largest orthopaedic companies from 2013 to 2017. Statistical analyses were conducted to investigate the factors that contributed to payment differences. Results:. Among the 347 highest-compensated orthopaedic surgeons, only 1 woman (0.29%) was identified. Orthopaedic surgeons in the subspecialties of spine (32.9%), adult reconstruction (27.9%), and sports medicine (14.5%) made up a majority of the 25 highest earners. A larger proportion of the physicians in this study worked in private practice (57.6%) compared with an academic setting (42.4%). Orthopaedic surgeons who subspecialize in sports medicine had significantly higher total mean payment amounts when compared with all other specialties. The primary method of compensation was found to be through licensing or royalty payments. Conclusions:. The large majority of orthopaedic surgeons who are highly compensated from industry are men. Among these, the greatest number specialize in the spine, while sports medicine surgeons receive significantly higher total mean payment amounts. Additional studies are warranted to evaluate the disparities between men and women and encourage policies to promote gender equality.

Background: Accessible, adequate online information is important to fellowship applicants. Program web sites can affect which programs applicants apply to, subsequently altering interview costs incurred by both parties and ultimately impacting rank lists. Web site analyses have been performed for all orthopaedic subspecialties other than those involved in the combined adult reconstruction and musculoskeletal (MSK) oncology fellowship match. Methods: A complete list of active programs was obtained from the official adult reconstruction and MSK oncology society web sites. Web site accessibility was assessed using a structured Google search. Accessible web sites were evaluated based on 21 previously reported content criteria. Results: Seventy-four adult reconstruction programs and 11 MSK oncology programs were listed on the official society web sites. Web sites were identified and accessible for 58 (78%) adult reconstruction and 9 (82%) MSK oncology fellowship programs. No web site contained all content criteria and more than half of both adult reconstruction and MSK oncology web sites failed to include 12 of the 21 criteria. Conclusions: Several programs participating in the combined Adult Reconstructive Hip and Knee/Musculoskeletal Oncology Fellowship Match did not have accessible web sites. Of the web sites that were accessible, none contained comprehensive information and the majority lacked information that has been previously identified as being important to perspective applicants.

Background: The National COVID Cohort Collaborative (N3C) is an innovative approach to integrate real-world clinical observations into a harmonized database during the time of the COVID-19 pandemic when clinical research on ankle fracture surgery is otherwise mostly limited to expert opinion and research letters. The purpose of this manuscript is to introduce the largest cohort of US ankle fracture surgery patients to date with a comparison between lab-confirmed COVID-19–positive and COVID-19–negative. Methods: A retrospective cohort of adults with ankle fracture surgery using data from the N3C database with patients undergoing surgery between March 2020 and June 2021. The database is an NIH-funded platform through which the harmonized clinical data from 46 sites is stored. Patient characteristics included body mass index, Charlson Comorbidity Index, and smoking status. Outcomes included 30-day mortality, overall mortality, surgical site infection (SSI), deep SSI, acute kidney injury, pulmonary embolism, deep vein thrombosis, sepsis, time to surgery, and length of stay. COVID-19–positive patients were compared to COVID-19–negative controls to investigate perioperative outcomes during the pandemic. Results: A total population of 8.4 million patient records was queried, identifying 4735 adults with ankle fracture surgery. The COVID-19–positive group (n=158, 3.3%) had significantly longer times to surgery (6.5 ± 6.6 vs 5.1 ± 5.5 days, P = .001) and longer lengths of stay (8.3 ± 23.5 vs 4.3 ± 7.4 days, P < .001), compared to the COVID-19–negative group. The COVID-19–positive group also had a higher rate of 30-day mortality. Conclusion: Patients with ankle fracture surgery had longer time to surgery and prolonged hospitalizations in COVID-19–positive patients compared to those who tested negative (average delay was about 1 day and increased length of hospitalization was about 4 days). Few perioperative events were observed in either group. Overall, the risks associated with COVID-19 were measurable but not substantial. Level of Evidence : Level III, retrospective cohort study.

Category: Ankle; Trauma Introduction/Purpose: Coronavirus (COVID-19) is an emerging, rapidly evolving situation. The National COVID Cohort Collaborative (N3C) is an innovative approach to integrate real-world clinical observations into a harmonized database. To investigate the outcomes of adults with ankle fracture surgery during the (COVID-19) pandemic, we had the following research question: What are the outcomes of ankle fracture patients with COVID-19 (invasive ventilation, length of stay, death)? The purpose of this abstract is to introduce the largest cohort of ankle fracture patients to date with a comparison between lab- confirmed COVID-19-positive and COVID-19-negative. Methods: A retrospective cohort of adults with ankle fracture surgery in the N3C Data Enclave. The N3C Data Enclave is an NIH-funded, secure platform through which the harmonized clinical data from electronic health records is stored ( https://covid.cd2h.org/ ). COVID-19 status was determined using a set of 55 SARS-CoV-2 polymerase chain reaction and antigen lab tests. Ankle fracture surgery was defined using SNOMED codes for 'fracture of bone' and one of the following CPT codes '27766, 27769, 27792, 27814, 27822, 27823, 27829' for 'ankle fracture surgery.' Results: A total population of 3.4 million patient records was queried in the National COVID Cohort, identifying 2,032 participants with ankle fracture surgery. The age range of the overall group was 18-98 years. Comparing COVID-19-positive to COVID-19-negative, the age (48.9 years vs 47.7 years) and gender (66.7% female vs 55.1% female) distribution of each group were comparable (both p>0.05). COVID-19-positive comprised 2.4% of the group (n=48). The length of stay was 4.7 days longer in the COVID-19-positive group (8.7 days vs 4.0 days, p
