Abstract
Component malposition in resurfacing arthroplasty can cause impingement, reduced range
of motion, increased metal wear, and early failure. It is therefore important that
any component malposition is recognized early and monitored carefully. We present
a case of delayed diagnosis of excess acetabular component anteversion causing posterior
femoral neck impingement and pain. We correlate the degree of damage found intraoperatively
with the degree of component malposition on the radiographs. This is used as a platform
to discuss the optimum positioning of hip resurfacing components and the radiographic
methods used to determine component position postoperatively.
