Management of hip dislocation following DHS fixation: A rare case report

Abstract

Dynamic hip screw (DHS) is an excellent implant for fixation of intertrochanteric fracture which helps the fracture components to slide together and impact, thus converting shearing force to compressive force. However, increased bending load over medial femoral cortex, excessive collapse at the fracture site, and unwanted rotation of proximal fragment lead to some cases of failure. Dislocation of hip following DHS fixation is the rarest of rare complications and probably not reported in literatures. We present one such case managed by two-staged total hip replacement using stability-range of motion prosthesis.
