RESUMEN
OBJECTIVE: The aim of this study was to assess applicant and fellowship director (FD) perspectives on virtual interviewing based on the 2019 to 2020 orthopaedic trauma fellowship interview experience and to develop recommendations for future application cycles. METHODS: Web-based surveys were distributed to all matched applicants and orthopaedic trauma FDs after the 2019 and 2020 orthopaedic trauma fellowship match. Thirty-one applicants and 23 FDs completed the survey-response rates of 34% and 38%, respectively. RESULTS: Virtual interviews were completed by 68% of applicants and 17% of FDs. Twenty-nine percent of applicants felt they were able to familiarize themselves with the culture of programs, and 38% of applicants were satisfied with their ability to present themselves. Most (62%) were comfortable ranking programs based on the virtual interview, but 38% reported the format influenced them to rank a program lower. Among all applicants, 77% preferred the in-person interview. Most FDs (75%) reported virtual interviews limited their ability to familiarize themselves with an applicant, and only 50% were comfortable ranking an applicant afterward. Still, 78% of FDs believe there is a role for virtual interviews in the fellowship match. Choosing a virtual interview may negatively affect applicants as 97% of applicants worry the choice conveys less interest to programs, while 43% of FDs would interpret it as less interest. CONCLUSIONS: Virtual interviews have multiple shortcomings but are technically feasible and provide reasonable information to applicants and FDs to complete the match process. Our recommendations, based on the perspectives of applicants and FDs, can guide their implementation.
RESUMEN
Social media can influence how students and residents learn about and select graduate medical education programs. COVID-19-related travel restrictions forced residencies to adapt their recruitment strategies. The objective of our investigation was to characterize the prevalence of social media use by orthopaedic surgery residency programs and to examine any change over time before the COVID-19 pandemic and leading up to the 2020 to 2021 virtual interview season. METHODS: The Fellowship and Residency Electronic Interactive Database was queried for all orthopaedic surgery residency programs (N = 164). We performed a cross-sectional analysis on the use of Facebook, Twitter, and Instagram by orthopaedic surgery residency programs in May 2019, July 2020, and November 2020. Orthopaedic surgery residency programs were systematically identified on each of the social media platforms. Descriptive statistics were used to facilitate comparisons between the time points. RESULTS: Seventy-six social media accounts were identified in May 2019 compared with 239 in November 2020-a greater than 300% increase in 19 months. The prevalence of residency programs using Facebook increased from 21.3% in May 2019 to 30.5% in July 2020 to 36.0% in November 2020. Similar increases in prevalence were identified for Twitter (15.2%-31.7% then 43.9%) and Instagram (9.1% to 37.2% to 65.9%). In May 2019, we identified 35 programs with Facebook accounts, 26 with Twitter accounts, and 15 with Instagram accounts. By November 2020, this increased to 59 Facebook accounts, 72 Twitter accounts, and 108 Instagram accounts. This corresponds to an expansion in the use of each platform by 69%, 177%, and 620% for Facebook, Twitter, and Instagram, respectively. CONCLUSIONS: The use of social media by academic orthopaedic surgery residency programs increased substantially over the study period. The adoption of Instagram seems to be occurring at the fastest rate. Social media may represent a useful tool in resident recruitment, but the platform must be carefully selected and planned to avoid unintended dilemmas.
RESUMEN
INTRODUCTION: Applying to orthopaedic surgery residency is competitive. Online information and mentorship are important tools applicants use to learn about programs and navigate the process. We aimed to identify which resources applicants use and their perspectives on those resources. METHODS: We surveyed all applicants at a single residency program for the 2018 to 2019 application cycle (n = 610) regarding the importance of online resources and mentors during the application process. We defined mentorship as advice from faculty advisors or counselors, orthopaedic residents, medical school alumni, or other medical students. We also assessed their attitudes about the quality and availability of these resources. Applicants were asked to rank resources and complete Likert scales (1 to 5) to indicate the relative utility and quality of options. Descriptive statistics were used to summarize data for comparisons. RESULTS: The response rate was 42% (259 of 610 applicants). Almost 50% of applicants reported that they would have likely applied to fewer programs if they had better information. Applicants used program websites with the highest cumulative frequency (96%), followed by advice from medical school faculty/counselors and advice from orthopaedic residents at home institution (both 82%). The next two most popular online resources were a circulating Google Document (78%) and the Doximity Residency Navigator (73%). On average, the quality of online resources was felt to be poorer than mentorship with advice from orthopaedic residents receiving the highest quality rating (4.16) and being ranked most frequently as a top three resource (122 votes). Mentorship comprised three of the top five highest mean quality ratings and three of the top five cumulative rankings by usefulness. CONCLUSION: Applicants reference online resources frequently, despite valuing mentorship more. If the orthopaedic community fostered better mentorship for applicants, they may not feel compelled to rely on subpar online information. Both online information and mentorship can be improved to create a more effective application experience.

OBJECTIVE: The medical profession seeks to hire and train individuals who consistently meet and/or exceed both job and cultural expectations. Resident selection is often not structured to meet this goal. The objective of this quality improvement project was to evaluate a classic unscripted interview process (OI) in conjunction with a structured, scripted interview process (SI) developed using an established hiring methodology from industry not yet utilized in health care. Qualitative questions we sought to answer: (1) Can SI be practically applied to the selection of residents? (2) Is there a significant difference in the relative position of applicants between the OI and SI rank lists? (3) Qualitatively, does SI help the evaluation/discussion of the affective domain? METHODS: Design: Prospective qualitative comparison of OI versus SI. SETTING: Dartmouth Hitchcock Medical Center, Lebanon, NH. PARTICIPANTS: Applicants were assessed by OI and SI. SI factors were selected based on a job profile. Interview scripts were created from validated behavioral and attitudinal questions. Online assessments assessed 2 important attributes - adaptability and values. Rank lists were compared for relative rank position of applicants. Feedback from faculty was obtained. RESULTS: Fifty-two applicants. Critical attributes were self-management, integrator-synthesizer, versatility, communication, and achievement. Absolute mean difference in rank/applicant was 9.8 (standard deviation 8.9, Range 0-36) positions. Comparing the top 20 candidates of each rank list, 40% of those applicants were only on one list. Faculty felt that applicants were given a greater opportunity to show "who they are." CONCLUSIONS: In conjunction with OI, an industry proven methodology was practically applied to define and select for high performance for the authors' specific institution. Comparing OI and SI resulted in substantial differences in rank lists. This initiative seemed to provide a structure to evaluate values and motivations that are inherently difficult to assess. Faculty felt SI in conjunction with OI gave a greater chance for applicants to show "who they are."

BACKGROUND: Foot and ankle surgeons are increasingly relying on patient-reported outcome measures (PROMs) such as the Ankle Osteoarthritis Scale (AOS) to evaluate treatment options. The objectives of this retrospective cohort study were 2-fold: (1) to examine the AOS instrument using psychometric analysis and (2) to revise the questions on the AOS to improve the effect of questions on the score and remove redundancies. METHODS: Pre- and postoperative patient scores were obtained from AOS questionnaires in the COFAS Prospective Ankle Reconstruction Database, a cohort of patients operatively treated for end-stage ankle arthritis. A split-sample approach was used to evaluate the AOS and to propose a revised instrument. RESULTS: A total of 380 patients who had been treated with total ankle replacement or ankle arthrodesis were prospectively followed to the 2-year postoperative time point. Correlation analysis demonstrated that a number of questions on the AOS were highly correlated with other similar questions, frequently incomplete, or showed little variation between respondents. Eight of the original AOS questions were retained in the newly proposed Ankle Arthritis Score (AAS) [3 from the AOS Pain subscale and 5 from the AOS Disability subscale]. Principal components analysis (PCA) showed that these questions equally clustered into 2 domains in AAS: Basic Activity and Advanced Activity. CONCLUSIONS: The AAS is shorter and has improved psychometric properties as compared to the AOS. Further investigation is required to better characterize the clinical utility of this proposed new patient-reported outcome score. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

BACKGROUND: There is much debate regarding the best outcome tool for use in foot and ankle surgery, specifically in patients with ankle arthritis. The Ankle Osteoarthritis Scale (AOS) is a validated, disease-specific score. The goals of this study were to investigate the clinical performance of the AOS and to determine a minimal clinically important difference (MCID) for it, using a large cohort of 238 patients undergoing surgery for end-stage ankle arthritis. METHODS: Patients treated with total ankle arthroplasty or ankle arthrodesis were prospectively followed for a minimum of two years at a single site. Data on demographics, comorbidities, AOS score, Short Form-36 results, and the relationship between expectations and satisfaction were collected at baseline (preoperatively), at six and twelve months, and then yearly thereafter. A linear regression analysis examined the variables affecting the change in AOS scores between baseline and the two-year follow-up. An MCID in the AOS change score was then determined by employing an anchor question, which asked patients to rate their relief from symptoms after surgery. RESULTS: Surgical treatment of end-stage ankle arthritis resulted in a mean improvement (and standard deviation) of 31.2 ± 22.7 points in the AOS score two years after surgery. The MCID of the AOS change score was a mean of 28.0 ± 17.9 points. The change in AOS score was significantly affected by the preoperative AOS score, smoking, back pain, and age. CONCLUSIONS: Patients undergoing arthroplasty or arthrodesis for end-stage ankle arthritis experienced a mean improvement in AOS score that was greater than the estimated MCID (31.2 versus 28.0 points).

This study sought to determine whether a grand rounds presentation could change resident practice. A 6-month review of all hip fracture patients 65 years and older at a single academic medical center was performed. The rate of addressing advanced directives and code status as documented in the medical record was noted. A grand rounds presentation was then given to the orthopedic department, and the medical records of hip fracture patients for the 12 months following the grand rounds were reviewed. In the 6 months prior to the grand rounds, orthopedic residents did not document code status or advanced directives in any of their admission or consultation notes. Following the grand rounds, orthopedic residents addressed advanced directives, code status, and contact person in 76% of their admission notes. There was a marked difference in the rate of documentation among residents who attended the grand rounds (88%), compared with residents who did not attend grand rounds (20%). Based on the results of this study, specifically whether residents attended grand rounds, this form of teaching can lead to changes in resident behavior.

BACKGROUND: Intra-articular ganglion cysts of the knee are extremely rare within the pediatric population. To our knowledge, only seven case reports have been published in the medical literature identifying pediatric patients with intra-articular cysts of the anterior cruciate ligament (ACL). Intra-articular cysts of the knee are a rare cause of knee discomfort and mechanical symptoms such as locking of the knee. To our knowledge, up until now the youngest patient reported in the medical literature with an intra-articular ganglion cyst of the ACL was a 7-year-old boy. CASE REPORT: We describe a 6-year-old boy who presented with a unilateral intra-articular ganglion cyst of the ACL in the right knee. In addition to the diagnostic work-up of radiographs and MRI, the cyst was successfully treated with arthroscopic resection and debridement to decompress the cyst. CLINICAL RELEVANCE: We provide a review of the proposed pathogenesis, diagnostic modalities, differential diagnosis, treatment options, and complications of treatment for intra-articular cysts of the ACL. LEVEL OF EVIDENCE: Level V, case report.

BACKGROUND: Hemiarthroplasty (humeral head replacement [HHR]) and reverse shoulder arthroplasty (RSA) are surgical options for cuff tear arthropathy (CTA). RSA may provide better pain relief and functional outcomes, but it costs more and may have a higher complication rate. The goal of this study was to compare the cost-effectiveness of these two treatments and to use sensitivity analysis to determine the drivers of the model. MATERIALS AND METHODS: A Markov decision model was used. Outcome and complication probabilities were obtained from existing literature. Costs were based on average Medicare reimbursement and implant prices. Utilities were derived from responses to health state surveys (Short Form 6D) from 31 patients at one institution who underwent RSA or HHR for CTA. Incremental cost-effectiveness ratios were used to compare treatments. RESULTS: Our model showed RSA could be a cost-effective strategy for treatment of CTA, using $100,000 per quality-adjusted life-year gained as a cutoff and the Short Form 6D for utilities. The model was extremely sensitive to the complication rate and the utility of each procedure and was also sensitive to implant price, with an implant price <$13,000 making RSA cost-effective. CONCLUSIONS: Currently available cost and outcome data show that RSA could be a cost-effective alternative to HHR for CTA. The cost-effectiveness of RSA depends most on the health utility gained from the operation, the utility lost due to complications from the operation, and the cost of the implant. Dropping the implant price to <$7,000 increases cost-effectiveness to <$50,000 per quality-adjusted life-year gained. Further head-to-head studies evaluating the clinical and quality of life outcomes of these two treatments are warranted.

BACKGROUND: Previous clinical studies have identified the cervical facet joint, including the capsular ligaments, as sources of pain in whiplash patients. The goal of this study was to determine whether whiplash caused increased capsular ligament laxity by applying quasi-static loading to whiplash-exposed and control capsular ligaments. METHODS: A total of 66 capsular ligament specimens (C2/3 to C7/T1) were prepared from 12 cervical spines (6 whiplash-exposed and 6 control). The whiplash-exposed spines had been previously rear impacted at a maximum peak T1 horizontal acceleration of 8 g. Capsular ligaments were elongated at 1mm/s in increments of 0.05 mm until a tensile force of 5 N was achieved and subsequently returned to neutral position. Four pre-conditioning cycles were performed and data from the load phase of the fifth cycle were used for subsequent analyses. Ligament elongation was computed at tensile forces of 0, 0.25, 0.5, 0.75, 1.0, 2.5, and 5.0 N. Two factor, non-repeated measures ANOVA (P<0.05) was performed to determine significant differences in the average ligament elongation at tensile forces of 0 and 5 N between the whiplash-exposed and control groups and between spinal levels. FINDINGS: Average elongation of the whiplash-exposed capsular ligaments was significantly greater than that of the control ligaments at tensile forces of 0 and 5 N. No significant differences between spinal levels were observed. INTERPRETATION: Capsular ligament injuries, in the form of increased laxity, may be one component perpetuating chronic pain and clinical instability in whiplash patients.

BACKGROUND CONTEXT: Most previous studies have investigated ligament mechanical properties at slow elongation rates of less than 25 mm/s. PURPOSE: To determine the tensile mechanical properties, at a fast elongation rate, of intact human cervical anterior and posterior longitudinal, capsular, and interspinous and supraspinous ligaments, middle-third disc, and ligamentum flavum. STUDY DESIGN/SETTING: In vitro biomechanical study. METHODS: A total of 97 intact bone-ligament-bone specimens (C2-C3 to C7-T1) were prepared from six cervical spines (average age: 80.6 years, range, 71 to 92 years) and were elongated to complete rupture at an average (SD) peak rate of 723 (106) mm/s using a custom-built apparatus. Nonlinear force versus elongation curves were plotted and peak force, peak elongation, peak energy, and stiffness were statistically compared (p<.05) among ligaments. A mathematical model was developed to determine the quasi-static physiological ligament elongation. RESULTS: Highest average peak force, up to 244.4 and 220.0 N in the ligamentum flavum and capsular ligament, respectively, were significantly greater than in the anterior longitudinal ligament and middle-third disc. Highest peak elongation reached 5.9 mm in the intraspinous and supraspinous ligaments, significantly greater than in the middle-third disc. Highest peak energy of 0.57 J was attained in the capsular ligament, significantly greater than in the anterior longitudinal ligament and middle-third disc. Average stiffness was generally greatest in the ligamentum flavum and least in the intraspinous and supraspinous ligaments. For all ligaments, peak elongation was greater than average physiological elongation computed using the mathematical model. CONCLUSIONS: Comparison of the present results with previously reported data indicated that high-speed elongation may cause cervical ligaments to fail at a higher peak force and smaller peak elongation and they may be stiffer and absorb less energy, as compared with a slow elongation rate. These comparisons may be useful to clinicians for diagnosing cervical ligament injuries based upon the specific trauma.

BACKGROUND: Although type A aortic dissections represent a surgical emergency, some patients present late after the onset of symptoms. Optimal management of this cohort has not been defined. METHODS: Data on 195 patients with type A dissections followed up at a single institution between 1985 and 2005 were collected prospectively. Of these, 93 patients (47.2%) presented 48 hours or later after the initial onset of pain (group A), and the remaining 102 patients underwent immediate operative repair (group B). Median follow-up was 41.8 months (range, 0 to 386 months). RESULTS: Patients in group A were older (68.8 versus 59.3 years, p = 0.0005) and had a higher incidence of coronary artery disease (42.5% versus 14.6%, p < 0.0001), pulmonary disease (26.6% versus 8.4%, p = 0.0023), and congestive heart failure (14.1% versus 1.0%, p = 0.0004). Long-term survival was similar, although group B showed a trend toward improved 30-day mortality (16.5% versus 8.7%, p = 0.1035). Of the 92 patients in group A, 53 (57.6%) eventually underwent operative repair a median of 8.2 days after symptom onset. There was a trend toward improved long-term survival among patients undergoing repair (p = 0.1031). CONCLUSIONS: Initial medical management with interval operative repair of selected patients referred greater than 2 days following an acute type A dissection is a viable option. Delayed repair after optimization of the clinical condition and detailed evaluation of concomitant diseases results in excellent long-term results.

BACKGROUND: Previous clinical studies have documented successful neck pain relief in whiplash patients using nerve block and radiofrequency ablation of facet joint afferents, including capsular ligament nerves. No previous study has documented injuries to the neck ligaments as determined by altered dynamic mechanical properties due to whiplash. The goal of the present study was to determine the dynamic mechanical properties of whiplash-exposed human cervical spine ligaments. Additionally, the present data were compared to previously reported control data. The ligaments included the anterior and posterior longitudinal, capsular, and interspinous and supraspinous ligaments, middle-third disc, and ligamentum flavum. METHODS: A total of 98 bone-ligament-bone specimens (C2-C3 to C7-T1) were prepared from six cervical spines following 3.5, 5, 6.5, and 8 g rear impacts and pre- and post-impact flexibility testing. The specimens were elongated to failure at a peak rate of 725 (SD 95) mm/s. Failure force, elongation, and energy absorbed, as well as stiffness were determined. The mechanical properties were statistically compared among ligaments, and to the control data (significance level: P < 0.05; trend: P < 0.1). The average physiological ligament elongation was determined using a mathematical model. RESULTS: For all whiplash-exposed ligaments, the average failure elongation exceeded the average physiological elongation. The highest average failure force of 204.6 N was observed in the ligamentum flavum, significantly greater than in middle-third disc and interspinous and supraspinous ligaments. The highest average failure elongation of 4.9 mm was observed in the interspinous and supraspinous ligaments, significantly greater than in the anterior longitudinal ligament, middle-third disc, and ligamentum flavum. The average energy absorbed ranged from 0.04 J by the middle-third disc to 0.44 J by the capsular ligament. The ligamentum flavum was the stiffest ligament, while the interspinous and supraspinous ligaments were most flexible. The whiplash-exposed ligaments had significantly lower (P = 0.036) failure force, 149.4 vs. 186.0 N, and a trend (P = 0.078) towards less energy absorption capacity, 308.6 vs. 397.0 J, as compared to the control data. CONCLUSION: The present decreases in neck ligament strength due to whiplash provide support for the ligament-injury hypothesis of whiplash syndrome.

BACKGROUND: Optimal operative decision making in thoracic aortic aneurysms requires accurate information on the risk of complications during expectant management. Cumulative and yearly risks of rupture, dissection, and death before operative repair increase with increasing aortic size, but previous work has not addressed the impact of relative aortic size on complication rates. METHODS: Our institutional database contains data on 805 patients followed up serially with thoracic aortic aneurysms. Body surface area information was obtained on 410 patients (257 male, 153 female). We calculated a new measure of relative aortic size, the "aortic size index," and examined its ability to predict complications in these patients. RESULTS: Increasing aortic size index was a significant predictor of increasing rates of rupture (p = 0.0014) as well as the combined endpoint of rupture, death, or dissection (p < 0.0001). Using aortic size index, patients were stratified into three risk groups: less than 2.75 cm/m2 are at low risk (approximately 4% per year), 2.75 to 4.24 cm/m2 are at moderate risk (approximately 8% per year), and those above 4.25 cm/m2 are at high risk (approximately 20% per year). CONCLUSIONS: This study confirms that (1) thoracic aortic aneurysm is a lethal disease, (2) relative aortic size is more important than absolute aortic size in predicting complications, and (3) a novel measurement of relative aortic size allows for the stratification of patients into three levels of risk, enabling appropriate surgical decision-making.

Since the first description of aortic dissection in the 1700s, the understanding and treatment of this catastrophic disease has evolved. Aortic dissections are identified as a tear in the aortic intima and inner layer of the media that allows for blood flow within the aortic wall. The area of the vessel involved determines its classification. The classification, in turn, helps to predict outcomes, which allows for appropriate treatment planning. The goal of this article is to outline the operative indications and timing for Stanford type A and type B dissections, based on prior reported data and our own clinical experience with 176 patients treated surgically at the Yale Center for Thoracic Aortic Disease. With this data we will revisit the importance of looking at each patient individually to devise an appropriate operative plan, with the knowledge that treatment for type A dissections is operative and treatment for type B dissections is medical unless patients present with actual or impending rupture, malperfusion, or failure of medical management.
