Atraumatic Failure of the DePuy Synthes Trochanteric Fixation Nail Advanced Fenestrated Cephalic Lag Screw

Abstract

Case: Extracapsular proximal femur fractures are a common injury that can be reliably treated with cephalomedullary nailing. We present 2 cases of atraumatic DePuy Synthes Trochanteric Fixation Nail Advanced implant failure through cephalic lag screw fenestrations in the setting of intertrochanteric fracture. Conclusion: Fenestrated lag screws inserted without cement augmentation may be susceptible to fatigue failure. Patients with unstable fracture patterns and other risk factors for delayed healing should undergo close clinical follow-up.
