RESUMEN
Postoperative periprosthetic humeral shaft fractures represent a growing and difficult complication to treat given the aging patient population and associated bone loss. Determining the best treatment option is multifactorial, including patient characteristics, fracture pattern, remaining bone stock, and implant stability. Possible treatment options include nonoperative management with bracing or surgical intervention. Nonoperative treatment has been shown to have higher nonunion rates, thus should only be selected for a specific patient population with minimally displaced fractures or those that are unfit for surgery. Surgical management is recommended with prosthetic loosening, fracture nonunion, or failure of nonoperative treatment. Surgical options include open reduction and internal fixation, revision arthroplasty, or hybrid fixation. Careful evaluation, decision making, and planning is required in the treatment of these fractures.
RESUMEN
Collegiate female gymnasts are at high risk of Achilles tendon injuries. Achilles tendon ruptures can negatively impact an athlete's ability to return to competitive sport. Understanding the natural history of Achilles tendon tears in collegiate female gymnasts is important in the development of preventive treatment. To expand our knowledge of the natural history of Achilles tendon ruptures among collegiate female gymnasts, a REDCap retrospective survey was emailed to athletic trainers on all 80 National Collegiate Athletic Association (NCAA) women's gymnastics teams. The survey gathered information regarding number of Achilles tendon injuries, pain prior to injuries, events and skills on which injuries occurred, and functional outcome after injuries among athletes competing in the 2013 to 2018 NCAA seasons. Forty-two of 80 (52.5%) programs responded to the survey. Seventy-one Achilles tendon ruptures were reported between 2013 and 2018. Among these, 46% had antecedent pain. Gymnasts sustained 95% of Achilles tendon ruptures while performing on floor exercise, with 98% of ruptures occurring during the take-off portion of a tumbling skill. Of the 61% of gymnasts who were able to return to competition, 59% were able to achieve the same level of function after injury. Achilles tendon ruptures in collegiate female gymnasts primarily occur during the take-off motion while tumbling on the floor exercise. Future studies should evaluate degenerative Achilles tendon changes in collegiate female gymnasts. A collaborative effort among gymnasts, coaches, judges, and medical experts is required to identify at-risk athletes and develop and implement injury prevention programs.

Most massive rotator cuff tears (MCTs) are often successfully treated with nonoperative treatment; however, various surgical treatment options are available if conservative management fails. Several joint preserving techniques for MCT are commonly used, but the options are limited if an MCT is irreparable. Reverse total shoulder arthroplasty (RTSA) is gaining popularity over hemiarthroplasty as a treatment option for irreparable MCT, especially if glenohumeral degenerative changes are present. RTSA has been shown to have improved functional outcomes and range of motion postoperatively, particularly in the elderly and patients with pseudoparalysis.

PURPOSE: To compare radiographic parameters of acetabular morphology between standard and modified false-profile (FP) radiographs. METHODS: Standard and modified FP radiographs were obtained in 225 hips in 200 consecutive patients evaluated for hip pain and suspected femoroacetabular impingement. Radiographs were retrospectively reviewed by 2 readers to determine the anterior center-edge angle (ACEA), as assessed to the sourcil and to the bone edge. Inter-rater reliability of radiographic measurements was assessed using the intraclass correlation coefficient. Measurements were evaluated for normality with the Shapiro-Wilk test, averaged between the 2 readers, and compared between views using the paired Wilcoxon test. RESULTS: The intraclass correlation coefficient values for standard and modified FP views were 0.923 and 0.932, respectively, measuring to the sourcil and 0.867 and 0.896, respectively, measuring to the lateral bone edge. The median difference in ACEA measurements to the sourcil was 1° between the standard and modified FP view (45° vs 44°, P < .001). The median difference in ACEA measurements to the bone edge was 2° (34° vs 32°, P < .001). CONCLUSIONS: Thirty-five degrees of femoral internal rotation for a modified FP hip radiographic view provides similar clinical information regarding acetabular morphology to that of the standard FP view. Given that the modified FP view also provides better visualization of the anterosuperior head-neck junction cam lesion, the modified FP view may be preferred over the standard FP view in evaluation of hip pain in the young patient. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

PURPOSE: The purpose of this study was to quantify the amount of internal femur rotation required to visualize the 12 to 3 o'clock positions of the femoral head-neck junction as seen on the false-profile radiograph. METHODS: Computed tomography (CT) images of the femur were retrospectively reviewed from control subjects and cam femoroacetabular impingement (FAI) patients. Using an automatically determined clockface, the positions between 12 and 3 o'clock were determined. The optimal femoral rotation angle to visualize each clockface position on the femoral head-neck junction was calculated based on the CT surface data. RESULTS: Fifty-nine control subjects and 38 cam FAI patients were evaluated for this study. The mean (95% confidence interval) internal femur rotation needed to optimally visualize the clockface positions of the femoral head-neck junction on the modified false-profile radiograph were 0.9° (0.8°-1.0°) for 3:00, 10.3° (10.0°-10.6°) for 2:30, 21.6° (21.0°-22.1°) for 2:00, 34.3° (33.6°-35.1°) for 1:30, 49.6° (48.6°-50.4°) for 1:00, 68.4° (67.7°-69.0°) for 12:30, and 90.1° (89.9°-90.4°) for 12:00. CONCLUSIONS: Internal femur rotation of 35° during the false-profile radiograph may better visualize the femoral head-neck junction in the anterosuperior (1 to 2 o'clock) region commonly associated with the cam lesion. From this view, rotation angles between 0° and 90° can be used to visualize other regions of the anterosuperior femoral head-neck junction. CLINICAL RELEVANCE: The internal rotation of the affected femur for a modified false-profile radiograph may provide a new radiographic view that can be used to quantify anterosuperior femoral head-neck morphology.
