Abstract

A 40-year-male treated with hip screw for unstable inter trochanteric fracture femur, had an implant failure after an aggressive therapy session .The Dynamic Condylar Screw was removed and fracture was fixed with Proximal Femoral Nail. The nail also failed to achieve its goal of fracture union, as a result of a unique type of reverse Z effect, in contradiction to expected Z effect resulting in intrapelvic migration of proximal hip lag screw of the proximal femoral nail.
