Operative and radiographic acetabular component orientation in total hip replacement: Influence of pelvic orientation and surgical positioning technique

Current survivorship of a primary total hip replacement (THR) exceeds 90% at ten years [1]. Despite this success, negative outcomes such as dislocation [2] and wear [3] persist. Mal-alignment of the implanted acetabular component is one factor that has been implicated [3 –5]. Great variability in acetabular component orientation is currently observed from post-operative radiographs [6–8]. A number of factors contribute to this variation with the most important being intra-operative pelvic orientation [9–10].
