RESUMO
OBJECTIVES: Hamstring strain injuries (HSI) are common among football and soccer athletes. Eccentric strength imbalance is considered a contributing factor for HSI. There is, however, a paucity of data on hamstring imbalances of soccer and American football athletes as they age and advance in skill level. High school athletes will display greater interlimb discrepancies compared with collegiate and professional athletes. In addition, soccer athletes will exhibit greater hamstring asymmetry than American football athletes. METHODS: Hamstring testing was performed on soccer and American football athletes using the NordBord Hamstring Testing System (Vald Performance, Albion, Australia). Age, sex, weight, sport specialization, and sport level were recorded. Maximum hamstring forces (N), torque (N · m), and work (N · s) were measured. Hamstring imbalance (%) was calculated by dividing the absolute value of the difference in leg forces divided by their sum. One-way analysis of variance and independent sample t tests compared measurements between athlete groups. RESULTS: A total of 631 athletes completed measurements, including 88 high school male soccer, 25 college male soccer, 23 professional male soccer, 83 high school female soccer, 28 college female soccer, 288 high school football, and 96 college football athletes. High school soccer players displayed significantly greater imbalances for torque (P = 0.03) and work (P < 0.01) than football athletes. Imbalances for maximum force (P = 0.035), torque (P = 0.018), and work (P = 0.033) were significantly higher for male soccer athletes in high school compared with college- and professional-level athletes. Female high school soccer players had significantly higher imbalance in torque (P = 0.045) and work (P = 0.001) compared with female collegiate soccer players. Football athletes did not experience significant changes in force imbalances between skill levels. CONCLUSIONS: High school soccer athletes exhibit greater hamstring imbalances than football athletes. Higher levels of play in soccer, for both male and female athletes, correlate with less hamstring asymmetry.

OBJECTIVES: Patients with private healthcare plans often defer nonemergent or elective procedures toward the end of the year once they have met their deductible. No previous studies have evaluated how insurance status and hospital setting may affect surgical timing for upper extremity procedures. Our study aimed to evaluate the influence of insurance and hospital setting on end-of-the-year surgical cases for elective carpometacarpal (CMC) arthroplasty, carpal tunnel, cubital tunnel, and trigger finger release, and nonelective distal radius fixation. METHODS: Insurance provider and surgical dates were gathered from two institutions' electronic medical records (one university, one physician-owned hospital) for those undergoing CMC arthroplasty, carpal tunnel release, cubital tunnel release, trigger finger release, and distal radius fixation from January 2010 to December 2019. Dates were converted into corresponding fiscal quarters (Q1-Q4). Using the Poisson exact test, comparisons were made between the case volume rate of Q1-Q3 and Q4 for private insurance and then for public insurance. RESULTS: Overall, case counts were greater in Q4 than the rest of the year at both institutions. There was a significantly greater proportion of privately insured patients undergoing hand and upper extremity surgery at the physician-owned hospital than the university center (physician owned: 69.7%, university: 50.3%; P < 0.001). Privately insured patients underwent CMC arthroplasty and carpal tunnel release at a significantly greater rate in Q4 compared with Q1-Q3 for both institutions. Publicly insured patients did not experience an increase in carpal tunnel releases during the same period at both institutions. CONCLUSIONS: Privately insured patients underwent elective CMC arthroplasty and carpal tunnel release procedures in Q4 at a significantly greater rate than publicly insured patients. This finding suggests private insurance status, and potentially deductibles, influence surgical decision making and timing. Further work is needed to evaluate the impact of deductibles on surgical planning and the financial and medical impact of delaying elective surgeries.

OBJECTIVES: Osteoarthritis (OA) is one of the most prevalent musculoskeletal ailments worldwide. Numerous conservative therapies exist, but evidence for such treatments remains conflicting. Recently, there has been growing interest surrounding bioactive sleeves for managing knee arthritis; however, the literature on their efficacy for relieving pain and improving function in the setting of knee OA is limited. As such, we sought to investigate the effect of a bioactive sleeve on patient-reported outcome measures in a small cohort of patients with OA. METHODS: Patients with knee OA were given a bioactive sleeve (Reparel, Chico, CA) and asked to refrain from lifestyle modifications and intraarticular corticosteroid injections. Lysholm Knee Score, Oxford Knee Score, Knee Injury and OA Outcome Score (KOOS), Single Assessment Numeric Evaluation, and Visual Analog Scale score were obtained at baseline, 2 weeks, 6 weeks, and 3 months. OA severity was evaluated using the Kellgren and Lawrence (KL) classification system. The Wilcoxon signed rank test was used to compare baseline patient-reported outcomes with 2-week, 6-week, and 3-month time points. Bivariate correlation was used to evaluate the relation between patient-reported outcome measures and KL classification. RESULTS: The cohort was composed of 14 participants-4 males and 10 females-with a mean age of 62.2 ± 13.2 years and a body mass index of 33.7 ± 5.8. The average KL grade was 2.9 (range 2-4). KOOS pain, symptoms, activities of daily living, and quality of life increased significantly at 2 weeks, 6 weeks, and 3 months. KOOS sport and recreation significantly increased at 3 months. The Oxford Knee Score was significantly greater at 2 weeks, 6 weeks, and 3 months. The Lysholm Knee Score was significantly greater at 6 weeks and 3 months. The Single Assessment Numeric Evaluation attained significant improvement at 3 months, and the Visual Analog Scale improvement was significant at 2 weeks. No statistically significant difference was attained with University of California at Los Angeles activity score. Outcome scores did not correlate with KL classification. CONCLUSIONS: These data suggest that a bioactive sleeve may improve patient-reported pain, symptoms, and function in the setting of knee OA. Further research is needed to better understand the role of bioactive sleeves for patients with knee arthritis.

BACKGROUND: Following orthopedic surgery, patients frequently experience pain and discomfort. Multiple methods of regional anesthesia are available; however, the optimal technique to adequately manage pain while minimizing complications remains under investigation. This study aims to compare the complication rates and pain relief of single-injection, liposomal bupivacaine brachial plexus nerve block to a conventional, indwelling ropivacaine interscalene catheter (ISC) in patients undergoing arthroscopic shoulder surgery. We hypothesize that liposomal bupivacaine will have fewer patient complications with similar pain relief than an indwelling catheter. METHODS: Patients undergoing arthroscopic shoulder surgery were prospectively assessed after randomization into either ropivacaine ISC or single-injection liposomal bupivacaine brachial plexus nerve block (LB) arms. All patients were discharged with 5 analgesics (acetaminophen, methocarbamol, gabapentin, acetylsalicylic acid, and oxycodone) for as-needed pain relief. Preoperatively, patient demographics and baseline Visual Analog Scale, Single Assessment Numeric Evaluation, American Shoulder and Elbow Surgeons, and Penn Shoulder Scores were obtained. For the first four days postoperatively, complication rates (nausea, dyspnea, anesthetic site discomfort and/or irritation and/or leakage, and self-reported concerns and complications), pain, medication usage, and sleep data were assessed by phone survey every 12 hours. The primary outcome was overall complication rate. At 12 weeks postoperatively, Visual Analog Scale, Single Assessment Numeric Evaluation, American Shoulder and Elbow Surgeons, and Penn scores were reassessed. Outcome scores were compared with Mann-Whitney U tests, and demographics were compared with chi-squared tests. Significance was set at P < .05. RESULTS: A total of 63 individuals were allocated into ISC (N = 35) and in the LB arms (N = 28) for analysis. Demographics and preoperative patient-reported outcomes were not different between the arms. Patients in the LB arm experienced fewer (13.1%) overall complications than those in the ISC arm (29.8%) (P < .001), with patients in the ISC arm specifically reporting more anesthetic site discomfort (36.4% vs. 7.1%, P = .007), leakage (30.3% vs. 7.1%, P = .023), and 'other,' free-response complications (ISC: 21.2%; LB: 3.6%; P = .042). No differences were noted in pain, sleep, opioid use, or satisfaction between arms during the perioperative period. More nonopioid medications were consumed on average in the ISC (1.8 ± 1.4) than in the LB arm (1.4 ± 1.3) (P = .001), with greater reported use of acetylsalicylic acid (40.9% vs. 23.4% P < .001) and acetaminophen (69.5% vs. 59.6% P = .013). Patient-reported outcome scores did not differ between groups preoperatively or at 12 weeks. DISCUSSION: Patients receiving liposomal bupivacaine experienced fewer complications than traditional ISCs after arthroscopic shoulder surgery. Analgesia, sleep, satisfaction, and functional scores were similar between the 2 groups.

OBJECTIVES: The purpose of this study was to investigate the response in orthopedic surgery to the coronavirus disease 2019 (COVID-19) pandemic across the United States by surveying surgeons about their care setting, timing of restrictions on elective surgery, use of telehealth, and estimated economic impact. METHODS: A survey was distributed via REDCap through state orthopedic organizations between April and July 2020. The 22-question digital survey collected information regarding restrictions on elective procedures, location of care, utilization of telehealth, and estimated reductions in annual income. RESULTS: In this study, 192 participants responded to the survey (average age 49.9 ± 11.0 years, 92.7% male). Responses primarily originated from Alabama (30.2%), Georgia (30.2%), and Missouri (16.1%). The remainder of the responses were grouped into the category "other." Respondents did not vary significantly by state in operative setting or income type (salary, work relative value units, or collections). Most of the participants documented elective procedure restrictions in hospital and ambulatory settings. The highest frequency of closures occurred between March 18 and 20 (47% in hospital, 51% in ambulatory). Of the participants, financial loss estimates varied across states (P = 0.005), with 50% of physicians claiming >50% losses of income in Alabama (24% Georgia, 10% Missouri, 31% other). Regarding telehealth, practices set up for these services before 2020 varied across states. None of the orthopedic practices in Alabama had telehealth before the COVID-19 pandemic (Missouri 25%, Georgia 9%, other 8%, P = 0.06); however, respondents generally were split when considering the anticipation of implementing telehealth into routine practice. CONCLUSIONS: Most practices did implement restrictions for elective clinic visits and procedures early during the pandemic. COVID-19 ultimately will result in a large revenue loss for elective orthopedic practices. Services such as telehealth may help offset these losses and help deliver orthopedic care to patients remotely.

Intramedullary nails are specialized metal rods inserted into the medullary cavity of a fractured bone and secured to reduce load on the fracture site, provide stability, and permit healing. The purpose of this review is to highlight the biomechanics of orthopaedic intramedullary nailing, as well as discuss the biomechanical considerations that have shaped implant design and fixation technique in veterinary and human medicine. Relevant studies were included from the PubMed database and Google Scholar for discussion on the basic science and nail design of intramedullary nails. Implant design and implementation continues to progress, with new innovative designs currently under investigation. A lack of consensus remains on the superior implant material. Recent studies, particularly in human populations, have supported the use of reaming based on reoperation rates, nonunion rates, and dynamization. Design modifications, such as the expandable intramedullary nails and angle-stable interlocking designs, have been investigated as methods of improving cortical contact and resisting torsional stress. Intramedullary nailing is a valuable stabilization technique for long bone fractures across a variety of species. The technology continues to undergo design improvements in both veterinary and human medicine.
RESUMO
BACKGROUND: Physical therapy (PT) plays an important role in the recovery of function following anatomic total shoulder arthroplasty (aTSA). While several PT protocols have been published for these patients, there is no standardized protocol for aTSA rehabilitation. This lack of standardization may lead to confusion between patients and physicians, possibly resulting in suboptimal outcomes. This study examines how PT protocols provided by academic orthopedic surgery programs vary regarding therapeutic goals and activities following aTSA. METHODS: PT protocols for aTSA available online from the Accreditation Council for Graduate Medical Education accredited orthopedic surgery programs were included for review. Each protocol was analyzed to evaluate it for differences in recommendation of length of immobilization, range of motion (ROM) goals, start time for and progression of therapeutic exercises, and timing for return to functional activity. RESULTS: Of 175 accredited programs, 25 (14.2%) had protocols publicly available, programs (92%) recommended sling immobilization outside of therapy for an average of 4.4±2.0 weeks. Most protocols gave recommendations on starting active forward flexion (24 protocols, range 1-7 weeks), external rotation (22 protocols, range 1-7 weeks), and internal rotation (18 protocols, range 4-7 weeks). Full passive ROM was recommended at 10.8±5.7 weeks, and active ROM was 13.3±3.9 weeks, on average. ROM goals were inconsistent among protocols, with significant variations in recommended ROM and resistance exercise start times. Only 13 protocols (52%) gave recommendations on resuming recreational activities (mean, 17.4±4.4 weeks). CONCLUSIONS: Publicly available PT protocols for aTSA rehabilitation are highly variable. Level of evidence: IV.
RESUMO
The indications for fresh osteochondral allograft continue to increase. As a result, variations in graft processing and preservation methods have emerged. An understanding of these techniques is important when evaluating the optimal protocol for processing fresh osteochondral allografts prior to surgical implantation. The aim of this study is to review the literature and understand various tissue processing protocols of four leading tissue banks in the United States. Donor procurement, serological and microbiological testing, and storage procedures were compared among companies of interest. Similarities between the major tissue banks include donor screening, aseptic processing, and testing for microorganisms. Variability exists between these companies with relation to choice of storage media, antibiotic usage, storage temperature, and graft expiration dates. Potential exists for increased chondrocyte viability and lengthened time-to-expiration of the graft through a protocol of delicate tissue handling, proper choice of storage medium, adding hormones and growth factors like insulin growth factor-1 (IGF-1) to serum-free nutrient media, and storing these grafts closer to physiologic temperatures.

Background Graduate Medical Education (GME) research in orthopedic surgery is an important but underrepresented subject in the medical literature. It was unknown if orthopedic residency leaders were interested in a surgical education research collaborative (orthopedic collaborative). The objectives of this study were to assess the potential benefit of an orthopedic collaborative from orthopedic residency leaders and investigate the factors associated with the support of a research collaborative within a surgical subspecialty. Methodology An anonymous 19-question survey-based study was distributed through REDCap (Nashville, TN, USA) to orthopedic residency leaders in the United States, from July to October 2020. The main outcome was perceived benefit. Additional aspects included program characteristics, challenges in performing resident education research, and organizational issues such as authorship, frequency of study requests, and governance. Results Almost all orthopedic faculty leadership (99%, 73/74) stated that resident education and faculty development research projects would benefit from an orthopedic education research collaborative. In comparison to unsupportive respondents, younger age (P = 0.006), 15 or fewer years in practice (P = 0.04), and having 0 to 100 peer-reviewed publications (P = 0.047) were associated with support for an orthopedic collaborative. Conclusions Challenges related to survey-based study quality and generalizability at single institutions can benefit from multi-institutional collaboration to develop high-quality studies that capture a representative sample to support orthopedic surgery program development.
RESUMO
BACKGROUND: It is important for physicians to be familiar with statistical techniques commonly used in published medical research. Statistical errors in medical literature are common, and there is a reported lack of understanding regarding statistical knowledge necessary for data interpretation and journal reading. As study design has become increasingly complex, peer-reviewed literature poorly addresses and explains the most common statistical methods utilized across leading orthopedic journals. METHODS: Articles from 5 leading general and subspecialty orthopedic journals were compiled from 3 distinct time periods. After exclusions were applied, 9521 remained, and a random 5% sampling of these articles, balanced across journals and years, was conducted yielding 437 articles after additional exclusions. Information regarding the number of statistical tests used, power/sample size calculation, type of statistical tests used, level of evidence (LOE), study type, and study design was collected. RESULTS: The mean number of statistical tests across all 5 orthopedic journals increased from 1.39 to 2.29 by 2018 (pâ¯=â¯0.007). The percentage of articles that reported power/sample size analyses was not found to differ by year, but the value has increased from 2.6% in 1994 to 21.6% in 2018 (pâ¯=â¯0.081). The most commonly used statistical test was the t-test which was present in 20.5% of articles, followed by chi-square test (13%), Mann-Whitney analysis (12.6%) and analysis of variance (ANOVA, 9.6%). The mean number of tests was generally greater in articles from higher impact factor journals (pâ¯=â¯0.013). Studies with a LOE of I used the highest mean number of statistical tests (3.23) compared to studies with lower LOE ratings (range 1.66-2.69, p < 0.001). Randomized control trials used the highest mean number of statistical test (3.31), while case series used the lowest mean number of tests (1.57, p < 0.001). CONCLUSIONS: The mean number of statistical tests used per article has increased over the past 25 years with the t-test, chi-square test, Mann-Whitney analysis, and ANOVA being the most used statistical tests in leading orthopedic journals. Despite an increase in statistical tests it should be noted that there was a paucity in advance statistical testing within the orthopedic literature. This study displays important trends in data analysis and can serve as a guide to help clinicians and trainees better understand the statistics used in literature as well as identifying deficits within the literature that should be addressed to help progress the field of orthopedics.

Background: Glenohumeral dislocations often lead to glenoid bone loss and recurrent instability, warranting bony augmentation. While numerous biomechanical studies have investigated fixation methods to secure a graft to the glenoid, a review of available constructs has yet to be performed. Purpose: To synthesize the literature and compare the biomechanics of screw and suture button constructs for anterior glenoid bony augmentation. Study Design: Systematic review. Methods: A systematic review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. There were 2 independent reviewers who performed a literature search using the PubMed, Embase, and Google Scholar databases of studies published between 1950 and 2020. Studies were included that compared the biomechanical outcomes of fixation for the treatment of anterior shoulder instability with glenoid bone loss. Results: Overall, 13 of the 363 studies screened met the inclusion criteria. The included studies measured the biomechanical strength of screws or suture buttons on a cadaveric or synthetic Latarjet construct. Screws and suture buttons were biomechanically similar, as both constructs exhibited comparable loads at failure and final displacement. Screw type (diameter, threading, or composition) did not significantly affect construct strength, and double-screw fixation was superior to single-screw fixation. Additionally, 2 screws augmented with a small plate had a higher load at failure than screws that were not augmented. Unicortical double-screw fixation was inferior to bicortical double-screw fixation, although construct strength did not significantly decrease if 1 of these screws was unicortical. Further, 2 screws inserted at 15° off axis experienced significantly higher graft displacement and lower ultimate failure loads than those inserted at 0° parallel to the glenoid. Conclusion: Suture buttons provided comparable strength to screws and offer an effective alternative to reduce screw-related complications. Augmentation with a small plate may clinically enhance construct strength and decrease complications through the dispersion of force loads over a greater surface area. Differences in screw type did not appear to alter construct strength, provided that screws were placed parallel to the articular surface and were bicortical.
RESUMO
Objective The Accreditation Council for Graduate Medical Education (ACGME) guidelines require scholarly activity but do not specify what research-related activity is necessary to meet this requirement. The current components and opinions regarding research and its implementation that qualify as scholarly activity are unknown among US orthopedic surgery programs. We aimed to survey program directors of orthopedic surgery programs to evaluate and better understand the current state of research during training. Design A survey was sent to the program directors of all ACGME-accredited orthopedic surgery between 2019 and 2020 with questions evaluating each program's research requirements and barriers to improvement. Results One-hundred eighteen (N=118) surveys were collected from 94 academic (79.6%) and 24 community (21.4%) programs. Although nearly all (97.5%) programs required research for graduation, only 45% of them allotted protected time: 52 academic programs (55.3%) allotted a median of nine weeks (interquartile range (IQR): 8-12 weeks) of dedicated time and 13 community programs (54.2%) allotted six weeks (IQR: 4-28 weeks) (p=0.595). We distinguished dedicated research as either consecutive weeks or a formal research track for a year. All programs indicated a desire for an increased focus on basic science compared to the current focus on outcomes-based research (p=0.04). The greatest identified obstacle to research improvement reported by community programs was faculty and resource commitment (p=0.003). The overall level of satisfaction with the current research experience among directors is 50.8%. Conclusion Despite differences between academic and community programs, directors agree on shifting the focus of research toward basic science. To improve preclinical research, additional time may be required, and individualized improvement plans should be undertaken at academic and community programs alike.
RESUMO
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.
RESUMO
INTRODUCTION: Financial literacy is the individual ability and skill to make informed decisions in the management of resources within the financial marketplace to yield a lifetime of financial well-being. Residents across several subspecialties have demonstrated low levels of financial literacy, and it is thought that more financial education is needed during residency training. The purpose of this study is to perform a comprehensive evaluation on financial literacy and financial attitudes of orthopaedic surgery residents. The authors hypothesize that orthopaedic residents will have low levels of financial literacy and financial satisfaction. METHODS: A 46-question anonymous survey was administered through COERG (Collaborative Orthopaedic Educational Research Group) to 1028 orthopaedic surgery residents of all postgraduate year at 43 programs with broad national distribution. Resident demographics and survey responses regarding knowledge of finance and investment topics, application of financial principles, and personal financial status were compared. RESULTS: The survey response rate was 48% (494/1028). The average financial literacy score of all orthopaedic resident participants was 60.9% (±16.5%). A total of 35.5% of orthopaedic residents were satisfied with their current financial situation. Saving for retirement and lower loan burdens correlated with greater financial satisfaction in financial situation. Scores were higher in orthopaedic residents with greater childhood annual household income, no credit card debt, higher levels of parent education, and active retirement savings plans. CONCLUSIONS: Orthopaedic residents show significant deficits in overall financial and investment knowledge combined with a dissatisfaction with financial situations while in residency. Orthopaedic residency programs have the opportunity to implement program-sponsored training and financial resources to enhance the resident education experience.

Objective With the introduction of the Google Glass in 2013, the use of augmented reality (AR) and virtual reality (VR) technology has been sharply accelerating in the field of medicine. Despite numerous hurdles and inadequacies identified with the initial devices, current product offering and the need for remote patient care has driven advancements and adoption of the newer generation of devices. This study aims to evaluate the current use of augmented reality devices and the current hurdles to implementation by surveying authors who have recently published on this topic. Design A 22-question survey was shared with authors of 27 recent publications relating to usage of augmented reality in medicine between the years of 2019 and 2020. Results Eighty-two percent of participants were located in North America while the rest were located in Europe. Interestingly, over 65% of respondents were over the age of 40. Almost half of respondents (45%) used the technology for image review while almost a third (27%) used it for capturing and sharing video. Most concerns to implementation were related to privacy (38%) or reimbursement (33%). Conclusion Despite the hurdles reported by respondents, the advancements in AR/VR have come a long way since their introduction and have great potential for continued usage in medicine. Despite this, however, it is important to recognize that cost, security, and battery life continue to serve as hurdles preventing the widespread adoption of this technology to mass markets.
RESUMO
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.
RESUMO
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.
RESUMO
Background Pathologic conditions of the sesamoids can be a source of disabling pain for patients, particularly during toe-off. Some underlying causes include osteonecrosis, inflammation, arthritis, and fracture. Nonoperative treatment is the initial standard of care, and has demonstrated satisfactory outcomes overall; however, operative management may be indicated in cases of pain refractory to conservative management. Sesamoidectomy is an uncommon procedure with risk of potential complications, but may be warranted in select cases of failed nonoperative treatment. Methods A retrospective chart review was conducted at one institution from 2009 to 2018. Twelve patients diagnosed with fibular sesamoiditis were treated with sesamoidectomy. Baseline patient demographics as well as postoperative outcomes were recorded. Results All 12 patients underwent fibular sesamoidectomy using the plantar approach following which their symptom (pain) resolved. Average follow-up for this cohort was 35 months. Of the sample, two patients experienced transient neuritis, one patient developed a superficial infection, and one had painful postoperative scarring. Hallux varus deformity was not observed in any patients. Conclusion Fibular sesamoidectomy may be a safe, viable procedure for patients with sesamoiditis who fail conservative measures.
RESUMO
Non-infectious soft tissue lesions of the foot and ankle are relatively rare clinically. These include benign and malignant neoplasms, as well as non-neoplastic or pseudotumoral lesions such as ganglionic, synovial and epidermoid cysts, intermetatarsal and adventitious bursitis, inflammatory lesions like gouty tophi and rheumatoid nodules, Morton's neuroma, and granuloma annulare. A 48-year-old male with a history of medically treated tophaceous gout presented with left foot neuropathic pain and paresthesia, in the setting of a well-circumscribed soft tissue lesion of the second intermetatarsal space, suspected to be a Morton's neuroma. Magnetic resonance imaging (MRI) showed a 4.1 x 2.7 x 2.6 cm heterogeneous soft tissue mass containing multiple cystic areas. Excisional biopsy was performed and histologic examination revealed well-circumscribed nodules of amorphous material containing needle-shaped clefts, rimmed by histiocytes, and multinucleated giant cells consistent with a gouty tophus. This is the first case reported in the literature of an intermetatarsal gouty tophus causing neuropathic pain and paresthesia. While Morton's neuroma is the most common cause of this presentation, this case illustrates that other pseudotumoral lesions, such as a gouty tophus, may present similarly, and should be considered in the differential diagnosis. While most cases of tophaceous gout can be adequately treated with urate-lowering therapy, surgery may be indicated for tophi that do not resolve with medical treatment based upon symptom severity, compression of nearby structures, and functional impairment.
RESUMO
Introduction Readmission following revision orthopedic surgery imposes tremendous costs due to the increased length of stay, procedure complexity, and revision surgery. Following revision total hip arthroplasty, as many as one in five patients are readmitted postoperatively. Readmissions cost the federal government $17.4 billion annually. The purpose of this study was to identify risk factors for unplanned readmission following revision total hip arthroplasty. Methods This was a retrospective case series review of randomized revision total hip arthroplasties (THA) patients between 2008 and 2018. Exclusions were as follows: outside hospital revisions, staged revisions, revisions for infection, and bilateral revisions. Data were collected by manual chart review. Readmissions were tracked from discharge until the final follow-up. Results A total of 61 patients and 85 revision THAs were analyzed. Nineteen patients (31.1%) were readmitted; 31.6% of the readmitted patients had a coronary artery disease compared to 6.5% of non-readmitted patients. Readmission was also associated with obesity, former smokers, and hypertension. Also, the mean duration of follow-up was 26.5 months for readmitted patients as compared to 8.96 for non-readmitted patients. Conclusion Obesity, former tobacco use, younger age, coronary artery disease (CAD), and hypertension were associated with readmission. The medical optimization of patients with these risk factors prior to surgery could significantly lower costs relative to revision THA.
