Survival and outcomes of modular endoprosthetic reconstruction of the proximal femur for primary and non-primary bone tumors: Single institutional results
Journal of Orthopaedics(2021)
摘要
Purpose: This study assessed implant survival and dislocation following proximal femur tumor endoprosthetic replacement.Methods: Thirty-eight procedures were performed between 2005 and 2019. The cumulative incidence of implant revision was calculated with death as a competing risk.Results: The majority of endoprostheses were bipolar hemiarthroplasty (n = 33, 86.8%). The cumulative incidence of revision was 14.6% (95% CI, 3.2%-34.1%) at five years. Dislocation occurred in 7.9% (n = 3) of hips at a mean (SD) 44 +/- 35.2 days.Conclusions: Proximal femur tumor endoprosthetic replacement is a durable option that tends to outlive patients. Strict postoperative bracing may lower dislocation rates.
