RESUMO
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
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: Sling immobilization is commonly used following rotator cuff repair. The purpose of this study was to determine the detrimental impact of sling usage on mobility and balance in an older adult population through validated gait and balance testing. The authors hypothesize that sling use will negatively affect balance and stability. METHODS: This institutional review board-approved and registered randomized prospective clinical trial enrolled patients from 2019 to 2021. Following informed consent, patients were randomized into two groups: a sling worn (group 1) and no sling worn (group 2). Participants were assessed via the Edmonton Frail Scale as well as Tinetti gait and balance scoring. RESULTS: Fifty patients were included in the study, 23 (46%) men and 27 (54%) women, with a mean age of 72.2 years. The balance score median was 16.00 for participants not wearing a sling and 15.00 for participants wearing a sling. The gait score median was 12.00 for participants not wearing a sling and 11.50 for participants wearing a sling. The balance and gait scores were significantly greater when patients were not wearing a shoulder sling with P values of 0.006 and 0.011, respectively. The overall combined gait and balance score was significantly greater, with median values of 27.00 for participants not wearing a sling and 26.00 for participants wearing a sling (P = 0.001). Patients reported little to no anxiety about falling while wearing the sling, with a score of 0.16. CONCLUSIONS: Postoperative sling immobilization negatively affects balance and gait in the geriatric population, potentially increasing the risk of postoperative falls in an already at-risk population.

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 < .001), and 52% stronger at 15° (P = .004); however, at 30°, both were comparable (P = .180). Interestingly, single suspensory button at 15° was equivalent to a single screw at 0° (P = .310). For double fixation, suspensory buttons (DT) were 32% stronger than screws at 0° (P < .001) and 35% stronger than screws at 15° (P < .001). Both double fixation methods were comparable at 30° (P = .061). Suspensory buttons at 15° and 30° were equivalent to double screws at 0 (P = .280) and 15° (P = .772), respectively. Conclusion: These measurements indicate that the suspensory button has a significantly higher load to failure capacity over the screw fixation technique, perpendicularly and with up to 15° of angulation. These analyses also indicate that the suspensory button fixation offers superior strength even when positioned more obliquely than the screw fixation. Therefore, suspensory button fixation may confer more strength while offering greater margin for error when positioning the graft.
RESUMO
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
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
BACKGROUND: Outcomes following reverse total shoulder arthroplasty (RTSA) are influenced by surgical indications, surgical technique, implant design, and patient variables. The role of self-directed postoperative physical therapy after RTSA is poorly understood. The purpose of this study was to compare the functional and patient-reported outcomes (PROs) of a formal physical therapy (F-PT) program vs. a home therapy program after RTSA. METHODS: One hundred patients were prospectively randomized into 2 groups: F-PT and home-based physical therapy (H-PT). Patient demographic variables, range of motion (ROM) and strength measurements, and outcomes (Simple Shoulder Test, American Shoulder and Elbow Surgeons, Single Assessment Numeric Evaluation, visual analog scale, and Patient Health Questionnaire-2 scores) were collected preoperatively and at 6 weeks, 3 months, 6 months, 1 year, and 2 years postoperatively. Patient perceptions regarding their group assignment, F-PT vs. H-PT, were also assessed. RESULTS: Seventy patients were included for analysis, with 37 in the H-PT group and 33 in the F-PT group. Thirty patients in both groups had a minimum of 6 months' follow-up. The average length of follow-up was 20.8 months. Forward flexion, abduction, internal rotation, and external rotation ROM did not differ between groups at final follow-up. Strength did not differ between groups with the exception of external rotation, which was greater by 0.8 kilograms-force (kgf) with F-PT (P = .04). PROs at final follow-up did not differ between therapy groups. Patients receiving home-based therapy appreciated the convenience and cost savings, and the majority believed home therapy was less burdensome. CONCLUSION: Formal physical therapy and home-based physical therapy programs after RTSA result in similar improvements in ROM, strength, and PRO scores.

Costs of healthcare in the US continue to rise at rates that are unsustainable. Prior studies, most of which come from non-surgical specialties, indicate that a variety of strategies to teach this material are utilized but without consensus on best practices. No studies exist regarding the teaching of cost-effective care in orthopaedic residency training programs. The goal of this study was to assess the landscape in this area from the perspective of program leadership. Methods: A survey was developed that was sent to orthopaedic residency program leadership via email through their interaction with the COERG. Additional programs were included to enhance diversity of responding programs. The survey, based on those published from other areas of medicine, included questions about the experiences of the respondents in learning about cost-effective care, as well as how faculty and residents learned about this topic. Results: Seventy one percent (30) of respondents noted that their faculty did not receive formal training in cost-effective care, and education in this area was likely to come from the department, especially review of practice data (12, 44%). Only 19% (8) of respondents agreed with the statement that "the majority of teaching faculty in our program consistently model cost-effective healthcare to residents". Few of the programs (10, 24%) had formal curricula for residents regarding cost-effective care, and the primary mode of education in cost-effective care was through informal discussions with faculty (17, 43%). Few residents (3, 13%) were able to easily find the costs of tests or procedures. Discussion: There is not consistent education in cost-effective care for orthopaedic surgery program leadership, faculty, or trainees. The results of this survey demonstrate a need for discussion of best practices, including increasing access to cost data at a local level, and engaging with the AOA, CORD, and the American Academy of Orthopaedic Surgeons more broadly in the development of standard education modules for faculty and residents, to improve the current and future delivery of cost-effective musculoskeletal care.
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.

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.

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
OBJECTIVES: Reconstruction for a chronic patellar tendon rupture in a native knee is an uncommon surgical procedure. Although there have been case series investigating patient-reported outcomes, there is no systematic review of these studies to date. The purpose of this review is to synthesize the literature on this procedure to better understand its outcomes, complications, and surgical technique options. METHODS: A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify studies that reported outcomes and techniques of patellar tendon reconstruction for chronic disruption in native knees. Searches were conducted through MEDLINE using PubMed, Cochrane Database of Systematic Reviews, and clinicaltrials.gov. RESULTS: Ten studies with 103 patients and 105 knees were included. Results for nonnative (arthroplasty) knees were excluded. The mean patient age was 40.3 years, and the mean postsurgical follow-up time was 53.8 months. Of the 105 knees, 75% received a hamstring tendon graft, whereas 13% received a bone-tendon-bone graft and 7% received a whole extensor mechanism allograft. The mean preoperative range of motion was 113.8°, which improved to 126.0° postoperatively. The mean preoperative Lysholm score was 58.6, which improved to 86.0 postoperatively; 100% of patients returned to their normal work activities and 76% returned to their prior level of physical activity. There were no major complications reported in any of the included studies. CONCLUSIONS: Chronic patellar tendon disruption in a native knee is an uncommon injury that can result in significant limitations for patients. Although more research is needed to better elucidate which graft is best, outcomes after patellar tendon reconstruction for chronic tears appear to be satisfactory with current techniques.

OBJECTIVES: The stressors that National Football League (NFL) athletes face are well-described and documented with regard to multisystem afflictions and injury prevalence. However, the majority of literature discusses the short-term effects rather than long-term outcomes of playing professional football. The purpose of this study was to characterize the long-term musculoskeletal issues in the retired NFL population. METHODS: Publications from CENTRAL, Scopus, Medline, PubMed, Embase, and Google Scholar were searched from database inception to February 2021. A total of 9 cohort studies evaluating lower extremity arthritis in retired NFL athletes were included for review. Two reviewers extracted data from the individual studies, including demographic information (age, body mass index, length of career, position), injury descriptions (location of injury, number of injuries, diagnoses), and procedure (total knee and or hip arthroplasty) frequency. RESULTS: Arthritis in retired NFL players was more than twice as prevalent than the general United States male population (95% CI: 2.1-2.3). Ankle osteoarthritis was directly correlated with the number of foot and ankle injuries. Players <50 years of age had a 16.1 and 13.8 times higher risk of undergoing TKA and THA, respectively, when compared to the general population. In older age groups, this trend held with retired NFL players being at least 4.3 and 4.6 times more likely than members of the general population to undergo TKA and THA, respectively. CONCLUSION: This review demonstrates that the effects of NFL-related lower extremity injuries extend beyond the players' careers and present a higher risk for early-onset osteoarthritis and overall frequency of undergoing total knee and hip arthroplasty.

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.

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: 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
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.

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 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
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.
