Abstract: 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.

Objectives: To analyze the radiographic outcomes of intertrochanteric osteotomy for the treatment of femoral neck nonunion with “undercorrection” of the Pauwels angle and relative preservation of the proximal femoral anatomy. Design: Retrospective cohort study. Setting: Level-1 trauma center. Patients: Thirty-two patients with established femoral neck nonunions that had been treated with intertrochanteric osteotomy were retrospectively identified through Current Procedural Terminology codes. Seven patients were treated with 30 degree closing wedge osteotomy and 25 with a 20 degree or smaller osteotomy. Intervention: Valgus-producing intertrochanteric osteotomy with a blade plate. Main Outcome Measurements: Femoral neck and intertrochanteric osteotomy osseous union. Results: Thirty-one of 32 patients (97%) went on to osseous union of the femoral neck and all intertrochanteric osteotomies healed. There was no significant difference in the rate of union of the femoral neck between those patients treated with 30 versus 20 degree or less osteotomies. After osteotomy, the mean Pauwels angle decreased from 71 degrees (range 52–95 degrees) to 47 degrees (range 23–67 degrees) and the mean proximal femoral offset decreased by 11 mm (range 0–23 mm). Seven patients developed radiographic signs of avascular necrosis after osteotomy (22%). Three patients of these patients were converted to total hip arthroplasty (9%). Patients treated with a 30 degree osteotomy were more likely to develop avascular necrosis (67% vs. 12%, P-value = 0.014). Conclusions: Valgus-producing intertrochanteric osteotomy with a smaller degree of correction than has been traditionally described leads to an excellent rate of radiographic union while preserving more of the native proximal femoral anatomy. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
