Prosthesis dislocation following total hip arthroplasty; a comparison of posterior and lateral surgical approach

ABSTRACT

Introduction: Joint function and integrity can be restored by various techniques and the surgical approach which is used for this restoration is called as arthroplasty. Principal methods for Total Hip Arthroplasty are Direct and Posterior lateral approaches. The most convenient to perform is posterior approach however, dislocation have been reported in most of cases. The rates of hip dislocation may be decreased by direct lateral approach as it provides cup positioning in better way. Direct lateral approach may be considered widely in future if the results of this study show relative benefits
