title: Dislocation of total hip replacements. A comparative study of standard, long posterior wall and augmented acetabular components.
abstract: Augmentation of the acetabular component of total hip replacements is a method of increasing stability and preventing recurrent dislocation. We report a series of mechanical experiments designed to evaluate the turning moments and angles required to dislocate standard, long posterior wall and two different augmented prostheses.
