OBJECTIVES: To compare whether femoral version more closely mirrors the contralateral femur or a population norm estimate of 15 degrees of anteversion. METHODS: Design: Radiologic observational study. Setting: Level I Trauma Center. Patient Selection Criteria: Patients with no history of anatomy-altering femoral injury who underwent bilateral lower extremity computed tomography scans. Outcome Measures and Comparisons: Computed tomographies were analyzed to measure femoral version on each side. The asymmetry in femoral version between left and right in each patient (interfemoral rotational variance [IRV]) was recorded. The difference of each femur's version from a proposed population mean of 15 degrees of anteversion was also recorded. RESULTS: A total of 219 patients with a mean femoral version of 14.9 degrees ± 10.5 degrees of anteversion were included. Mean IRV was 5.3 degrees, compared with 8.2 degrees of mean variation from the population norm of 15 degrees of anteversion (P < 0.001). Five percent of patients had IRV >15 degrees compared with 15% that had femoral rotation >15 degrees from the population mean of 15 degrees (P < 0.001). CONCLUSIONS: In the setting of a comminuted diaphyseal femur fracture, knowledge of the appropriate target for restoration of rotational alignment is critical. This radiologic cohort study found that on average, femoral version more closely mirrors an individual patient's contralateral femur as opposed to a population norm of 15 degrees of anteversion.

Case: A 67-year-old woman sustained a periprosthetic tibial tubercle avulsion fracture with extensor mechanism disruption. She underwent open reduction internal fixation (ORIF) with orthogonal mini-fragment plates applied in a tension band fashion with patellar tendon suture augmentation. Radiographs, range of motion, and patient-reported outcomes were completed over 1 year. Conclusion: Isolated periprosthetic tibial tubercle fractures with disruption of the extensor mechanism can be treated with ORIF using orthogonal tension band plating. At 1-year follow-up, the surgical technique described in this report yielded radiographic union, clinical restoration of preinjury motion, and excellent patient-reported outcomes.

Introduction: To date, there has been a paucity of research evaluating the demographics, characteristics, and surgical training of orthopaedic residency program directors (PDs). Purpose: To determine the objective characteristics of orthopaedic residency PDs by analyzing their demographic characteristics, academic backgrounds, institutional histories, research productivity, and professional leadership affiliations. Methods: Data for each PD were collected by searching publicly available curriculum vitae , LinkedIn, Healthgrades, Doximity, and/or institutional biographies and consolidated into a database. Research productivities were collected by searching PubMed and Scopus. Results: Of the 210 PDs, 188 (89.5%) were male and 22 (10.5%) were female. One hundred seventy-four (82.9%) were non-Hispanic White, 14 (6.7%) Asian American and Pacific Islander, 12 (5.7%) Black or African American, 4 (1.9%) Hispanic or Latino, and 6 (2.9%) other/unknown. Twenty-four (11.4%) PDs had a military affiliation. Moreover, the most common subspecialties among orthopaedic PDs were orthopaedic traumatology (19.5%, n = 41), sports medicine (15.7%, n = 33), and hand surgery (11.9%, n = 25). The mean Scopus h -index, total number of publications at the time of data collection (June 2022), and total number of citations for all orthopaedic residency PDs were 10.5 ± 9.5, 33.9 ± 51.0, and 801.9 ± 1,536.4, respectively. Among all PDs, the mean tenure in the position was 8.9 ± 6.2 years to date, and the mean time from completion of residency to appointment as PD was 10.0 ± 6.2 years. Conclusions: Among orthopaedic surgery residency PDs, there is sparse female and minority representation. Overarchingly, orthopaedic PDs are White men in their early 50s. Moreover, 59.1% of PDs were appointed at an institution where they completed medical school, residency, or fellowship. orthopaedic traumatology (19.5%), sports medicine (15.7%), and hand surgery (11.9%) were the subspecialties most represented in current orthopaedic surgery PDs. Clinical Relevance: This study outlines important demographic characteristics among orthopaedic surgery residency PDs. Level of Evidence: III

Case: A 20-year-old man sustained a comminuted bone-patellar tendon-bone donor-site fracture 17 days after a contralateral anterior cruciate ligament revision reconstruction. Successful fixation was achieved by using a tricortical iliac crest allograft bone plug with mesh plate osteosynthesis. At 6 months of follow-up, the patient had full range of motion without pain. Conclusion: Patellar fractures after bone-patellar tendon-bone harvest may be treated successfully with mesh plate osteosynthesis and a tricortical iliac crest allograft bone plug. This unique fixation option addresses bone loss and restores the extensor mechanism while avoiding autograft donor site morbidity.
