The Asymmetric Profile of the Acetabulum

Abstract: Despite the curvaceous profile of the acetabulum, orthopaedic surgeons have continued to implant hemispheric cups since the introduction of total hip arthroplasty. The geometric discrepancies between the natural acetabulum and implant can result in painful iliopsoas impingement attributable to prosthetic overlap at the anterior acetabular ridge over which the iliopsoas tendon extends to leave the pelvis. We expanded on previous in vitro observations of acetabular morphology using a large in vivo sample and qua… Show more

“…In agreement with a recent study [68], we measured the irregular configurations, but found the anterior rim depression was never straight. Two studies described a wave-like profile of the acetabular rim similar to that in our study [67,68]. Differences in the individual extent of the anterior and the posterior depressions in the more recent of these studies may be related to differences Fig.…”

“…One study denoted four configurations along the anterior rim as curved, angular, irregular, or straight [40]. In agreement with a recent study [68], we measured the irregular configurations, but found the anterior rim depression was never straight. Two studies described a wave-like profile of the acetabular rim similar to that in our study [67,68].…”
