PURPOSE: The nature and focus of hand surgery fellowships has been shown to vary. Compounding this issue is a paucity of information regarding the educational goals and desires of prospective fellows. The purpose of this study was to understand applicant motivation for pursuing a fellowship and the most important components of these fellowships.

METHODS: We performed an anonymous survey of all the candidates who applied for a hand surgery fellowship during the 2019-2020 academic year to establish general demographic information, preferences regarding fellowship size, and the importance of various educational and logistical components. We also recorded self-reported comfort level in treating pathologies encountered during a hand-focused subspecialty practice.

RESULTS: The most important motivation cited for pursuing a fellowship in hand surgery was the "complexity and variety of cases" (n = 55, 90%). The 5 most important desired components of a fellowship were the exposure to "bread and butter" hand surgery (n = 35, 57%), ability to take level 1 hand call (n = 26, 43%), exposure to complex wrist reconstruction (n = 26, 43%) or peripheral nerve surgery/transfers (n = 23, 38%), and soft tissue coverage including free flaps (n = 19, 31%). Further analysis revealed that the orthopedic surgery residents frequently rated exposure to level 1 call (n = 20, 45%) as 1 of their 3 most important characteristics, whereas the plastic/general surgery residents frequently ranked exposure to complex wrist reconstruction (n = 16, 38%) as 1 of their 3 most important characteristics. The components of a fellowship that received the fewest selections into an applicant's top 3 components were exposure to shoulder surgery (n = 1, 1.64%), education regarding practice building/billing (n = 2, 3.2%), and the ability to conduct research (n = 4, 6.5%).

CONCLUSIONS: Most applicants pursue a subspecialty training in hand surgery because of the field's variety and breadth of cases. The applicants prioritize exposure to "bread and butter" cases in conjunction with both complex soft tissue and microsurgical reconstruction.

CLINICAL RELEVANCE: Assisting hand fellowships in understanding what is most important to prospective fellows will allow for appropriate recruitment and development of the field of hand surgery in general.

BACKGROUND:  The benefits of preoperative perforator imaging for microsurgical reconstruction have been well established in the literature.

METHODS:  An extensive literature review was performed to determine the most commonly used modalities, and their applicability, advantages and disadvantages.

RESULTS:  The review demonstrated varioius findings including decreases in operative time and cost with the use of CT angiography to identification of perforators for inclusion in flap design with hand-held Doppler ultrasound. Modalities like MR angiography offer alternatives for patients with contrast allergies or renal dysfunction while maintaining a high level of clarity and fidelity. Although the use of conventional angiography has decreased due to the availability of less invasive alternatives, it continues to serve a role in the preoperative evaluation of patients for lower extremity reconstruction. Duplex ultrasonography has been of great interest recently as an inexpensive, risk free, and extraordinarily accurate diagnostic tool. Emerging technologies such as indocyanine green fluorescence angiography and dynamic infrared thermography provide real-time information about tissue vascularity and perfusion without requiring radiation exposure.

CONCLUSION:  This article presents an in-depth review of the various imaging modalities available to reconstructive surgeons and includes hand held Doppler ultrasound, CT angiography, MR angiography, conventional angiography, duplex ultrasonography, Indocyanine Green Fluorescence Angiography and Dynamic Infrared Thermography.

BACKGROUND: Markers of bone metabolism (MBM) play an important role in fracture evaluation, and changes have been associated with increased fracture risk. The purpose of the present study was to describe changes in MBM in premenopausal women with distal radial fractures.

METHODS: Premenopausal women with distal radial fractures (n = 34) and without fractures (controls) (n = 39) were recruited. Serum MBM in patients with distal radial fractures were obtained at the time of the initial presentation, 6 weeks, and 3, 6, and 12 months. MBM included 25(OH) vitamin D, PTH, osteocalcin, P1NP, BSAP, CTX, sclerostin, DKK1, periostin, and TRAP5b. Areal bone mineral density (aBMD) was assessed with dual x-ray absorptiometry, and the bone material strength index (BMSi) was assessed with microindentation.

RESULTS: Most MBM reached peak levels at 6 weeks after the injury, including osteocalcin (+17.7%), sclerostin (+23.5%), and DKK1 (12.6%). Sclerostin was lower (-27.4%) and DKK1 was higher (+22.2%) at 1 year after the fracture. CTX declined below baseline levels at 6 and 12 months, whereas TRAP5b, BSAP, and periostin did not significantly change. At 12 months, sclerostin was lower (p = 0.003) and DKK1 was higher (p = 0.03) in the distal radial fracture group than in the control group. Greater fracture severity was associated with greater increases in P1NP and BSAP. aBMD and BMSi were not associated with fracture.

CONCLUSIONS: Distal radial fractures caused increases in several MBM, which typically peaked at 6 weeks after injury and gradually decreased over 6 months. Sclerostin and DKK1 remained below and above baseline at 1 year, respectively. Increasing fracture severity resulted in larger changes in MBM. aBMD and BMSi did not discriminate between patients with distal radial fractures and controls. Continued efforts to identify markers of skeletal fragility in young women are warranted to mitigate future fracture risk.

Gluteal augmentation with autologous fat grafting is an increasingly popular procedure. While complication rates are low, the clinical and imaging evaluation of the various complications can be challenging. We report a case of distal migration of a failed gluteal fat graft in a young female patient presenting as a soft tissue mass in the knee, mimicking a soft tissue sarcoma. Surgical resection of the migrated fat graft confirmed the diagnosis. The diagnosis was challenging as the patient was initially reluctant to disclose her surgical history due to perceived negative social stigmas related to cosmetic contouring procedures. This case highlights the imaging findings of a rare complication following autologous fat grafting for gluteal augmentation and the importance of obtaining a thorough medical history.

OBJECTIVES: The incidence of periprosthetic femur fracture in the setting of total hip arthroplasty is steadily increasing. Although the traditional dogma is that loose femoral components must be revised, we propose that in a frail geriatric population, anatomic reduction and fixation of Vancouver B2 and B3 periprosthetic fracture variants can restore stem stability and provide similar outcomes as revision arthroplasty.

DESIGN: Retrospective cohort study.

SETTING: Level 1 trauma center, tertiary academic medical center.

PATIENTS/PARTICIPANTS: We identified 94 patients over 65 years of age with Vancouver B2 and B3 fractures sustained between 2005 and 2019.

INTERVENTION: Patients were treated by either open reduction and internal fixation (ORIF) or revision arthroplasty (RA) with or without fixation.

MAIN OUTCOME MEASUREMENTS: Outcomes were mortality, time to full weight-bearing after surgery, intraoperative estimated blood loss, perioperative complications, reoperation, subsidence rate, and Patient-Reported Outcomes Measurement Information System pain and physical function scores.

RESULTS: A total of 75 (79.8%) ORIF and 19 (20.2%) RA patients were reviewed. One-year mortality for our cohort was 26.3%, and there was no significant difference between groups. Mean time to weight bear and surgical complication rates were similar between groups. The ORIF group had a significantly shorter time to surgery than the RA group. The RA group had greater incidence and amount of subsidence as well as estimated blood loss than the ORIF group.

CONCLUSIONS: In geriatric patients with Vancouver B2 and B3 type periprosthetic fractures with known loose stems, ORIF may offer a similarly safe method of treatment than revision arthroplasty.

Historic and present-day marginalization has resulted in a high burden of disease and worse health outcomes for American Indian and Alaska Native (AI/AN) communities in the United States. Musculoskeletal disease is the leading cause of disability for the general population in the U.S. today. However, few have examined musculoskeletal disease burden and access to orthopaedic surgical care in the AI/AN communities. A high prevalence of hip dysplasia, arthritis, back pain, and diabetes, and a high incidence of trauma and road traffic-related mortality, suggest a disproportionately high burden of musculoskeletal pathology among the AI/AN communities and a substantial need for orthopaedic surgical services. Unfortunately, AI/AN patients face many barriers to receiving specialty care, including long travel distances and limited transportation to health facilities, inadequate staff and resources at Indian Health Service (IHS)-funded facilities, insufficient funding for referral to specialists outside of the IHS network, and sociocultural barriers that complicate health-system navigation and erode trust between patients and providers. For those who manage to access orthopaedic surgery, AI/AN patients face worse outcomes and more complications than White patients. There is an urgent need for orthopaedic surgeons to participate in improving the availability of quality orthopaedic services for AI/AN patients through training and support of local providers, volunteerism, advocating for a greater investment in the IHS Purchased/Referred Care program, expanding telemedicine capabilities, and supporting community-based participatory research activities.

OBJECTIVES: The current lack of agreement regarding standardized terminology in musculoskeletal and sports ultrasound presents challenges in education, clinical practice, and research. This consensus was developed to provide a reference to improve clarity and consistency in communication.

METHODS: A multidisciplinary expert panel was convened consisting of 18 members representing multiple specialty societies identified as key stakeholders in musculoskeletal and sports ultrasound. A Delphi process was used to reach consensus which was defined as group level agreement >80%.

RESULTS: Content was organized into seven general topics including: 1) General Definitions, 2) Equipment and Transducer Manipulation, 3) Anatomic and Descriptive Terminology, 4) Pathology, 5) Procedural Terminology, 6) Image Labeling, and 7) Documentation. Terms and definitions which reached consensus agreement are presented herein.

CONCLUSIONS: The historic use of multiple similar terms in the absence of precise definitions has led to confusion when conveying information between colleagues, patients, and third-party payers. This multidisciplinary expert consensus addresses multiple areas of variability in diagnostic ultrasound imaging and ultrasound-guided procedures related to musculoskeletal and sports medicine.

INTRODUCTION: When the COVID-19 pandemic forced the cancellation of visiting subinternships, we pivoted to create a virtual orthopaedic rotation (VOR). The purpose of this study was to assess the effect of the VOR on the residency selection process and determine the role of such a rotation in the future.

METHODS: A committee was convened to create a VOR to replace visiting orthopaedic rotations for medical students who are interested in pursuing a career in orthopaedic surgery. The VOR was reviewed and sanctioned by our medical school, but no academic credit was granted. We conducted three 3-week VOR sessions. During each session, virtual rotators participated in regularly scheduled educational conferences and attended an invitation-only daily conference in the evenings that was designed for a medical student audience. In addition, students were paired with faculty and resident mentors in a structured mentorship program. Students' orthopaedic knowledge was assessed using prerotation and postrotation tests.

RESULTS: From July to September 2020, 61 students from 37 distinct medical schools participated in the VOR. Notable improvements were observed in prerotation and postrotation orthopaedic knowledge test scores. In postrotation surveys, both students and faculty expressed high satisfaction with the curriculum but less certainty about how well they got to know each other. In the subsequent residency application cycle, 27.9% of the students who participated in the VOR were selected to interview, compared with 8.7% of the total application pool.

DISCUSSION: The VOR was a valuable substitute for in-person clinical rotations during the COVID-19 pandemic. Although not likely to be a replacement for conventional away rotations, the VOR is a possible adjunct to in-person clinical rotations in the future.

Globally, the burden of musculoskeletal conditions continues to rise, disproportionately affecting low and middle-income countries (LMICs). The ability to meet these orthopaedic surgical care demands remains a challenge. To help address these issues, many orthopaedic surgeons seek opportunities to provide humanitarian assistance to the populations in need. While many global orthopaedic initiatives are well-intentioned and can offer short-term benefits to the local communities, it is essential to emphasize training and the integration of local surgeon-leaders. The commitment to developing educational and investigative capacity, as well as fostering sustainable, mutually beneficial partnerships in low-resource settings, is critical. To this end, global health organizations, such as the Consortium of Orthopaedic Academic Traumatologists (COACT), work to promote and ensure the lasting sustainability of musculoskeletal trauma care worldwide. This article describes global orthopaedic efforts that can effectively address musculoskeletal care through an examination of 5 domains: clinical care, clinical research, surgical education, disaster response, and advocacy.
