Intertrochanteric fracture fixation in solid organ transplant patients: outcomes and survivorship

Background Solid organ transplantation (SOT) recipients have complex medical and surgical risk factors; however, the outcomes of these patients undergoing surgical fixation of hip fractures are unknown. This study sought to evaluate SOT patients’ outcomes and survivorship after intertrochanteric (IT) fracture fixation. Methods A retrospective review identified 12 SOT patients who underwent cephalomedullary (CMN) nail fixation for IT fractures and were matched (1:2) to a cohort of 24 non-SOT IT fracture patients. Perioperative results and complications, mortality/patient survivorship, and clinical outcomes were compared between the cohorts. Results The time from presentation to surgical fixation was within 48 h of presentation for the non-SOT patients, while only 75% of SOT patients underwent surgery within 48 h of presentation ( p = 0.034). The 90-day readmission rate for SOT patients was 25% versus 13% in the non-SOT group ( p = 0.38). Similarly, the SOT cohort experienced a higher rate of major medical complication (25% vs. 13%, p = 0.38). There were two (16%) reoperations in the SOT group and three (13%) in the non-SOT matched group ( p = 0.99). Respectively, the 90-day and 1-year estimated patient survivorship was similar between the two cohorts: SOT patients with 92% (95% CI 54–99%) and 73% (95% CI 24–93%) versus 86% (95% CI 62–95%) and 72% (95% CI 47–86%, HR 0.92, 95% CI 0.18–4.62, p = 0.92) in non-SOT patients. Conclusion SOT patients who underwent CMN fixation for IT fractures required more time from hospital presentation to surgical management than non-SOT patients. Although not statistically significant, SOT patients demonstrated more acute complications and readmissions, but similar mortality compared to those without transplant.
