There exists an unmet need for locally relevant and sustainable orthopedic research in low- and middle-income countries. Partnerships between high-income countries and low- and middle-income countries can bridge gaps in resources, knowledge, infrastructure, and skill. This article presents a select list of models for high-income countries/low- and middle-income countries research partnerships including academic partnerships, international research consortia, professional society-associated working groups, and nongovernmental organization partnerships. Models that produce research with lasting legacy are those that promote mutually beneficial partnerships over individual gains., Competing Interests: Disclosure Dr D.

BackgroundInternational orthopaedic resident rotations in low and middle-income countries (LMICs) are gaining popularity among high-income country (HIC) residency programs. While evidence demonstrates a benefit for the visiting residents, few studies have evaluated the impact of such rotations on the orthopaedic surgeons and trainees in LMICs. The purpose of this study was to further explore themes identified in a previous survey study regarding the local impact of visiting HIC resident rotations.MethodsUsing a semistructured interview guide, LMIC surgeons and trainees who had hosted HIC orthopaedic residents within the previous 10 years were interviewed until thematic saturation was reached.ResultsTwenty attending and resident orthopaedic surgeons from 8 LMICs were interviewed. Positive and negative effects of the visiting residents on clinical care, education, interpersonal relationships, and resource availability were identified. Seven recommendations for visiting resident rotations were highlighted, including a 1 to 2-month rotation length; visiting residents at the senior training level; site-specific prerotation orientation with an emphasis on resident attitudes, including the need for humility; creation of bidirectional opportunities; partnering with institutions with local training programs; and fostering mutually beneficial sustained relationships.ConclusionsThis study explores the perspectives of those who host visiting residents, a viewpoint that is underrepresented in the literature. Future research regarding HIC orthopaedic resident rotations in LMICs should include the perspectives of local surgeons and trainees to strive for mutually beneficial experiences to further strengthen and sustain such academic partnerships.

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.

Aims: This investigation develops a predictive model for loss of alignment (LOA) following fixation of open tibia fractures.Patients/methods: An analysis was performed of adults with diaphyseal open tibia fractures randomized to intramedullary nailing (IMN) or external fixation (EF) followed at 6, 12, 24, and 52 weeks postoperatively. Demographic data were collected at baseline. Pre-injury and follow-up EuroQol 5-Dimensions (EQ-5D) and pain score were measured. Radiographs, taken postoperatively and in follow-up, were assessed for coronal and sagittal angulation, and used to calculate the modified Radiographic Union Scale for Tibia fractures (mRUST). LOA was defined as an increase in angulation >5° by one year follow-up. Fracture comminution was defined using AO/OTA classification. Putative risk factors were assessed for association with LOA using bivariate logistic regression. Adjusted associations with LOA were estimated using multivariable logistic regression and marginal analysis.Results: Analyses included 129 patients (70 IMN, 59 EF), majority male, of mean age 33 years (range 17.7-73) and body mass index (BMI) 25.2 (range 15.5-45.1), with 48% Type A, 41% Type B, and 11% Type C fractures (AO/OTA classification). The likelihood of LOA with EF increased with greater fracture comminution; 45.21% (p<0.001), 77.50% (p<0.001), and 100% LOA for Type A, B, and C fractures respectively. Relative risk of LOA for EF compared to IMN was 3.87 (95% CI 1.36, 11.02), 3.75 (95% CI 1.77, 7.92), and 5.76 for Type A, B, and C fractures, respectively. Compared to patients who lost alignment, patients without LOA had improved fracture healing (p = 0.003) and higher EQ-5D scores (p = 0.03) at one year.Conclusion: Increasing age and BMI are associated with LOA and segmental fracture amplifies the protective effect of IMN versus EF. The importance of LOA as a surrogate outcome after operative treatment of open tibial fractures is supported by its association with inferior radiographic and functional patient outcomes.
