Recent Trends in the Effect of Race and Gender on the Orthopedics Match.

Introduction Orthopedics has a reputation for being competitive but not diverse. Leaders of the orthopedics community have been making efforts to increase the participation of women and minorities in the field by raising awareness and strengthening pipeline programs. We aim to explore the trends in the risk of not matching by comparing the proportions of women and underrepresented populations in the applicant pools versus proportions in residency programs. Simultaneously, we aim to evaluate if women or underrepresented population applicants exhibit a lower likelihood of applying to orthopedics compared to male and White applicants. Methods The study received an IRB exemption. The authors collected Accreditation Council for Graduate Medical Education (ACGME) data books for the years 2015-2016 to 2022-2023 to obtain demographic information on orthopedic residents in training during each of those academic years. The pool of corresponding applicants (for example: residents in training during the 2021-2022 academic year would consist of five classes, made up of applicants from 2016-2017 to 2020-2021) was then tabulated from Electronic Residency Applications Service (ERAS) statistics, which are publicly available on the Association of American Medical Colleges (AAMC) website. The race and gender composition of the applicant pool was compared to that of corresponding enrolled residents to calculate the relative risk (RR) of women not matching compared to men and underrepresented population applicants (Blacks, Hispanics, Asians, and Native Americans) compared to White applicants. ERAS data was subsequently used to calculate the percentages of each demographic applying to all residency programs and orthopedic programs. Results For female applicants into orthopedic residency, they had a similar RR of going unmatched when compared to their male counterparts. In the academic year 2020-2021, there was an exception to this as women had a slightly higher RR of going unmatched. All underrepresented populations had a higher risk of not matching compared to White applicants for all cycles, peaking for residents in training in 2020-2021. The trendline improved for residents in the following year. Throughout the study, women accounted for 46.61% of applicants applying for any residency; however, they only accounted for 16.98% of applicants applying for orthopedic residency. A similar discrepancy is noted among Asian applicants but not Black or Hispanic applicants. Conclusions Underrepresented populations were increasingly less likely to match into orthopedics relative to White applicants until 2021. In the academic year of 2021-2022, there was an improvement in this trend for all studied underrepresented populations. Although the exact explanation for this is unclear, it is associated with the transition to virtual applicant interactions. The female gender did not appear to be a consistent advantage or disadvantage in the match. Women and Asian applicants were less likely to apply to orthopedics than other specialties.

Is Grit Associated with Burnout and Well-being in Orthopaedic Resident and Faculty Physicians? A Multi-institution Longitudinal Study Across Training Levels.

BACKGROUND: Grit has been defined as "perseverance and passion for long-term goals" and is characterized by maintaining focus and motivation toward a challenging ambition despite setbacks. There are limited data on the impact of grit on burnout and psychologic well-being in orthopaedic surgery, as well as on which factors may be associated with these variables. QUESTIONS/PURPOSES: (1) Is grit inversely correlated with burnout in orthopaedic resident and faculty physicians? (2) Is grit positively correlated with psychologic well-being in orthopaedic resident and faculty physicians? (3) Which demographic characteristics are associated with grit in orthopaedic resident and faculty physicians? (4) Which demographic characteristics are associated with burnout and psychologic well-being in orthopaedic resident and faculty physicians? METHODS: This study was an institutional review board-approved interim analysis from the first year of a 5-year longitudinal study of grit, burnout, and psychologic well-being in order to assess baseline relationships between these variables before analyzing how they may change over time. Orthopaedic residents, fellows, and faculty from 14 academic medical centers were enrolled, and 30% (335 of 1129) responded. We analyzed for the potential of response bias and found no important differences between sites in low versus high response rates, nor between early and late responders. Participants completed an email-based survey consisting of the Duckworth Short Grit Scale, Maslach Burnout Inventory-Human Services (Medical Personnel) Survey, and Dupuy Psychological Well-being Index. The Short Grit Scale has been validated with regard to internal consistency, consensual and predictive validity, and test-retest stability. The Psychological Well-being Index has similarly been validated with regard to reliability, test-retest stability, and internal consistency, and the Maslach Burnout Inventory has been validated with regard to internal consistency, reliability, test-retest stability, and convergent validity. The survey also obtained basic demographic information such as survey participants' age, gender, race, ethnicity, marital status, current year of training or year in practice (as applicable), and region of practice. The studied population consisted of 166 faculty, 150 residents, and 19 fellows. Beyond the expected age differences between sub-populations, the fellow population had a higher proportion of women than the faculty and resident populations did. Pearson correlations and standardized ß coefficients were used to assess the relationships of grit, burnout, psychologic well-being, and continuous participant characteristics. RESULTS: We found moderate, negative relationships between grit and emotional exhaustion (r = -0.30; 95% CI -0.38 to -0.21; p < 0.001), depersonalization (r = -0.34; 95% CI -0.44 to -0.23; p < 0.001), and the overall burnout score (r = -0.39; 95% CI -0.48 to -0.31; p < 0.001). The results also showed a positive correlation between grit and personal accomplishment (r = 0.39; 95% CI 0.29 to 0.48; p < 0.001). We also found a moderate, positive relationship between grit and psychologic well-being (r = 0.39; 95% CI 0.30 to 0.49; p < 0.001). Orthopaedic surgeons with 21 years or more of practice had higher grit scores than physicians with 10 to 20 years of practice. Orthopaedic surgeons in practice for 21 years or more also had lower burnout scores than those in practice for 10 to 20 years. Married physicians had higher psychologic well-being than unmarried physicians did. CONCLUSION: Among orthopaedic residents, fellows, and faculty, grit is inversely related to burnout, with lower scores for emotional exhaustion and depersonalization and higher scores for personal accomplishment as grit increases. CLINICAL RELEVANCE: The results suggest that grit could be targeted as an intervention for reducing burnout and promoting psychologic well-being among orthopaedic surgeons. Other research has suggested that grit is influenced by internal characteristics, life experiences, and the external environment, suggesting that there is potential to increase one's grit. Residency programs and faculty development initiatives might consider measuring grit to assess for the risk of burnout, as well as offering curricula or training to promote this psychologic characteristic.

Chondrotoxicity of Local Anesthetics: Liposomal Bupivacaine Is Less Chondrotoxic than Standard Bupivacaine.

OBJECTIVE: The purpose of this study is to determine whether (1) liposomal bupivacaine is chondrotoxic; (2) the chondrotoxicity of liposomal bupivacaine differs from standard bupivacaine; and (3) chondrotoxic effects are time dependent. MATERIALS AND METHODS: We obtained 72 10 mm articular cartilage plugs from 12 fresh bovine distal femoral knee joints and exposed them to either saline, 0.5% bupivacaine, or liposomal bupivacaine for either 30 or 90 minutes. Twenty-four hours after treatment, chondrocyte viability was measured with the use of a fluorescent live/dead assay. An ANOVA test of variance was performed followed by a Holm-Sidak test to make pairwise comparisons across conditions. Student's t-test was used to compare means. RESULTS: Percent viability of cells exposed to liposomal bupivacaine for 30 minutes was less versus saline control (53.9% ± 21.5% vs. 73.7 ± 18.4%, p=0.035), and this remained significant at 90 minutes (49.1% ± 20.3% vs. 67.2% ± 25.6%, p < 0.001). Liposomal bupivacaine had less chondrotoxic effects when compared with bupivacaine after 90 minutes, with greater viability (49.1% ± 20.3% vs. 21.4% ± 14.0%, p=0.003). Chondrotoxicity was found to be time dependent within the bupivacaine group (percent viability at 30 min: 45.5 ± 18.2%, 90 min: 21.4 ± 14.0%, p=0.001); however, liposomal bupivacaine did not demonstrate a significant time-dependent chondrotoxic relationship (p=0.583). CONCLUSIONS: Bupivacaine and liposomal bupivacaine are both toxic to chondrocytes. Liposomal bupivacaine is less chondrotoxic than standard bupivacaine and does not demonstrate a time-dependent toxicity.

Factors Affecting Appropriateness of Interfacility Transfer for Hand Injuries.

BACKGROUND: Transfers of patients with higher acuity injuries to trauma centers have helped improve care since the enactment of Emergency Medical Treatment and Active Labor Act. However, an unintended consequence is the inappropriate transfer of patients who do not truly require handover of care. METHODS: We retrospectively reviewed the records of all patients transferred to our level I trauma center for injuries distal to the ulnohumeral joint between April 1, 2013, and March 31, 2014; 213 patients were included. We examined the records for appropriateness of transfer based on whether the patient required the care of the receiving hospital's attending surgeon (appropriate transfer) or whether junior-level residents treated the patient alone (inappropriate transfer) and calculated odds ratios. We performed logistic regression to identify factors associated with appropriateness of transfer; these factors included specialist evaluation prior to transfer, age, insurance status, race, injury type, sex, shift time, distance traveled, and median income. RESULTS: The risk of inappropriate transfers was 68.5% (146/213). Specialist evaluation at the referring hospital was not associated with a lower risk of inappropriate transfers (odds ratio 1.62 [95% CI: 0.48-5.34], P = .383). Only evening shift (15:01 to 23:00) was associated with inappropriate transfers. Amputations and open fractures were associated with appropriate transfers. CONCLUSION: Second shift and type of injury (namely, amputations and open fractures) were significant factors to appropriateness of transfer. No significant association was found between specialist evaluation and appropriate transfers. Future studies may focus on finding reasons and aligning incentives to minimize inappropriate transfers and associated systems costs.

Temperature Rise in Kirschner Wires Inserted Using Two Drilling Methods: Forward and Oscillation.

BACKGROUND: Kirschner wires (K-wires) are commonly used in orthopedic surgery. However, the loosening of the pins can lead to delayed or improper healing or infection. Wire loosening can occur by thermal necrosis that occurs due to heat produced during wire insertion. Although the parameters that affect temperature rise in cortical bone during wire insertion and drilling have been studied, the effect of drilling mode (oscillation versus forward) is unknown. The purpose of this study was to compare the temperature changes occurring in cortical bone during wire insertions by oscillating and forward drills. Our hypothesis is that oscillation drilling would produce less heat compared with forward drilling in K-wire insertion with 2 commonly used wire diameters. METHODS: We drilled K-wires in a pig metacarpal model and measured the temperature rise between forward and oscillation drilling modes using diamond-tipped 0.062- and 0.045-inch-diameter K-wires. There were 20 holes drilled for each group (n = 20). RESULTS: The average temperature rise using the 0.062-inch K-wire under forward and oscillation insertion was 14.0 ± 5.5°C and 8.8 ± 2.6°C, respectively. For the 0.045-inch K-wire, under forward and oscillation insertion, the average temperature rise was 11.4 ± 2.6°C and 7.1 ± 1.9°C, respectively. The effects of the drilling mode and wire diameter on temperature rise were significant ( P < .05). CONCLUSIONS: In conclusion, the oscillation of K-wires during insertion causes a lower temperature rise when compared with forward drilling.

The Opportunity Awaits to Lead Orthopaedic Telehealth Innovation: AOA Critical Issues.

Telehealth is a way to provide health-care services to a patient from a provider who is at another location. The most common methods include a live interactive visit with the patient, interpretation of imaging, and monitoring of patient progress. Principally, telehealth is a way of providing a service rather than a type of service. It is about patient care, not data care.Examples of orthopaedic applications include conducting patient examinations, interpreting imaging studies, and providing postoperative care. Teleconsultation has been shown to be cost-effective. Other examples in orthopaedic research include the application of telemedicine when measuring patient-reported outcomes. Especially in cases when the patient lives far away from the provider, telehealth reduces time, produces good patient satisfaction, and costs less than hands-on care. As in everyday life, consumers have learned to demand convenience, ease of use, choice, control, and direct access. The ubiquity of telecommunications, combined with consumer technology savviness, drives the demand for telehealth. Unfortunately, the nation's largest payer for health services is one of the most restrictive for telehealth coverage. Medicare's restrictions are mostly the work of the U.S. Congress under Part B law. Video visits are very narrowly covered. Another major policy barrier is that interstate telehealth requires multiple state licenses for the physician, who must be licensed in the jurisdiction of each patient as well as the provider's physical locations. As Medicare shifts toward capitated payment and other value-based methods, there are opportunities to remove such restrictions.Despite these challenges, some states have been proactive in implementing telehealth systems. Arkansas is one of these states, and being a rural state with 2 main population centers, specialty care is relatively sparse. Implemented in 2014, the hand trauma program has been a partnership between the University of Arkansas for Medical Sciences (UAMS) and the Arkansas Trauma Communications Center (ATCC). This program has been very successful in decreasing the rate of hand trauma transfer, allowing patients to be treated closer to home while having coordinated access to fellowship-trained hand surgeons when necessary.More widespread innovation of orthopaedic applications for telehealth requires physician buy-in and health-systems partnerships. The regulatory environment will need streamlining. Ultimately, consumer demand will drive the implementation of technology to make care more accessible, convenient, and cost-effective.

Erratum to: Editorial: Do Orthopaedic Surgeons Belong on the Sidelines at American Football Games?

In the November Editorial, "Editorial: Do Orthopaedic Surgeons Belong on the Sidelines at American Football Games?" a statistic was attributed to a JAMA study (Ref. 10) that should have been attributed to an article from the New York Times (Ref. 16). The sentence in question should read: "We accept that critique, provided that the skeptics acknowledge that the best-case estimate in support of the safety of football would result in a CTE prevalence estimate of 9%, since only another 1200 ex-NFL players have died [16] since this research group [10] began studying football players' brains."

Insurance-Mandated Stay Prolongs Hospitalization Following Total Shoulder Arthroplasty.

Medicare currently requires a 3-night hospitalization for a patient to be considered for skilled nursing facility (SNF) placement. The purpose of this study was to analyze the relationship between length of stay and (a) insurance status and (b) readmission rates in Medicare-age patients undergoing primary total shoulder arthroplasty. A retrospective review of 251 primary consecutive total shoulder arthroplasty cases was performed. In patients discharged to SNF, Medicare insurance was associated with a significantly longer hospital stay (p < .001) compared with patients with private insurance. Readmission rates for Medicare and private insurance patients were similar at 30 and 90 days after surgery (p = 1.000). Ninety-five percent of Medicare patients discharged to SNF had a prolonged hospital stay primarily to fulfill the 3-night requirement. These findings call into question the necessity of the current 3-night inpatient hospitalization requirement for facility placement following total shoulder arthroplasty.

Outcomes After Distal Radius Fracture Treatment With Percutaneous Wire Versus Plate Fixation: Meta-Analysis of Randomized Controlled Trials.

Multiple methods for surgical fixation of distal radius fractures exist, including percutaneous pinning with Kirschner wires and open reduction volar plating. Despite increased costs, the hypothesis of this study was that open reduction and volar plating does not provide improved outcomes over wire fixation. Following Transparent Reporting of Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a meta-analysis of randomized controlled trials was conducted comparing these two methods with regard to clinical outcomes, radiographic parameters, and complications. Seven trials with a total of 858 patients were included. Plating was not favored over pinning with regard to clinical outcomes and radiographic parameters. Pinning was associated with a higher superficial infection risk compared with plating, though the risk of repeat surgery was not different. It was concluded that Kirschner wire fixation, which may be associated with lower costs, is associated with similar clinical and radiographic outcomes when compared with volar plate fixation, although wire fixation is associated with higher superficial infection risk.

A Prospective Randomized Crossover Study on the Comparison of Cotton Versus Waterproof Cast Liners.

BACKGROUND: Many fractures are treated with casting which can cause complications likely from inability to wash the extremity. Gore-Tex-based waterproof cast liner has been compared with cotton liner and shown to be superior in physician and patient scoring but also has high cost and difficult application. The purpose of this study is to compare newer generation waterproof liners with traditional cotton liner. It is the first study to compare this new waterproof liner and cotton liner in a crossover model, allowing patients to swim in the pool with the cast. METHODS: Twenty patients (ages 3-30) with upper extremity injuries were randomized to waterproof-liner or cotton-liner casts made of fiberglass. Patients would switch cast liners halfway between their treatments to fulfill crossover criteria. All fractures were within a 2-week period from original incident. At each clinic visit, patients evaluated comfort parameters through questionnaires, and physicians rated skin condition. Patients were also asked which cast liner they preferred at the end of the study. RESULTS: There were no unscheduled cast changes. The waterproof-liner group had better scores for odor (P = .041), sweat (P = .016), and overall physician-rated score (P = .038). There was no significant difference in other patient-rated parameters. Seventy-five percent of patients preferred waterproof casting to the cotton liner. CONCLUSIONS: This new waterproof cast liner, compared with cotton cast liner, had better odor, sweat, and overall physician scores. The waterproof liners allow patients to rinse casts daily, and the majority of patients prefer waterproof to cotton liner.

Radiation Exposure and Hand Dominance Using Mini C-Arm Fluoroscopy in Hand Surgery.

BACKGROUND: The mini C-arm is popular with hand surgeons, and they are particularly at risk for radiation exposure, as they cannot easily distance themselves from the radiation beam. We hypothesized that the nondominant hand receives more radiation exposure than the dominant hand as it is generally closer to the radiation source. This study seeks to determine whether a hand surgeon receives a different amount of radiation exposure to their hands based on hand dominance and then accounting for this, provide a more accurate assessment of hand radiation exposure from mini C-arm fluoroscopy. METHODS: Two fellowship-trained hand surgeons wore ring dosimeters on both hands during surgeries with mini C-arm fluoroscopy involving bony work of the forearm and hand. Radiation exposure to the hands was measured from ring dosimeters. RESULTS: Six-ring dosimeter pairs were worn during 64 cases, averaging 10.7 cases per ring. No ring met the minimal dose threshold of 30 mrem to record a numerical value. Each ring experienced an average of 413 seconds of fluoroscopy time and 66.3509 cGy*cm(2) of radiation output from the mini C-arm. CONCLUSIONS: The results do not allow comparison of radiation exposure related to hand dominance. Assuming worst-case scenario: each ring measured 29 mrem (just below the threshold), the surgeon's hands experienced 2.7 mrem per case. This would allow a hand surgeon to perform 18 391 cases per year before exceeding the allowable annual hand exposure limit of 50 000 mrem set by the National Council of Radiation Protection and Measurements and International Commission on Radiological Protection.

Does Barbed Suture Repair Negate the Benefit of Peripheral Repair in Porcine Flexor Tendon?

Background: Advances in suture material and geometry have fueled interest in barbed suture tenorrhaphy. Theoretically, barbed suture allows better load distribution, smoother gliding under pulleys, and improved tendon blood flow. Minimal data exist on whether barbed tendon repair may benefit from supplementation by a peripheral stitch. The purpose of this study is to determine whether peripheral suture repair increases gap resistance in both conventional and barbed core repairs, increases maximum tensile strength, and fails before or after the core repair. Methods: Porcine flexor tendons were harvested and assigned randomly into 4 groups of 10 of varying suture constructs (3-0 PDS™ or 3-0 V-Loc 180™ core with or without peripheral 5-0 Vicryl™ repair). Core repairs were performed using a modified 4-strand cruciate repair. A servohydrolic tester was used for biomechanical testing of linear 2-mm gap resistance and maximum tensile strength. Results: Peripheral repair improved 2-mm gap resistance in all repairs, regardless of core suture type, conventional (173% increase) or barbed (204% increase). No change in the maximum tensile strength was found in either core suture type with peripheral repair. Peripheral repairs always failed before core repairs, at a significantly higher load of 74.2 ± 20.4 N in barbed versus 57.8 ± 12.2 N (P = .04) in conventional core repairs. Conclusions: The addition of peripheral repair improved gap resistance but not ultimate tensile strength in both conventional and barbed flexor tendon repairs in linear testing. The 4-strand cruciate flexor tendon repairs using barbed suture may require peripheral repair to withstand physiologic loads, as core repair alone using barbed suture was insufficient.
