Abstract

INTRODUCTION: We determined mortality rates after intraoperative and postoperative periprosthetic femur fractures in primary and revision total hip arthroplasty (THA). METHODS: The study population comprised 522 intraoperative and 480 postoperative femur fractures in 26,250 primary THA patients and 590 intraoperative and 224 postoperative femur fractures in 4,532 revision THA patients. The risk of death was examined using Cox regression models. RESULTS: In primary THA, intraoperative periprosthetic femur fractures were not associated with excess risk of death (hazard ratio, 1.03; 95% confidence interval, 0.86 to 1.22). The risk of death was slightly elevated among primary THA patients with postoperative femur fractures (hazard ratio, 1.19; 95% confidence interval, 1.08 to 1.43), but the excess risk was only confined to patients with comorbid orthopaedic conditions. In revision THA, neither intraoperative nor postoperative periprosthetic femur fractures were associated with excess risk of death. CONCLUSION: Periprosthetic femur fractures are not associated with excess mortality among primary osteoarthritis patients. LEVEL OF EVIDENCE: Level III.
