Malpositioning of the acetabular component is a common problem associated
with the posterior or posterolateral approach to total hip arthroplasty.
Retroversion is also a common problem due to forward rolling (or internal
rotation) of the patient during anterior femoral retraction
(Fig. 1). Hassan et al. stated
that anteversion cannot be assessed accurately during
surgery1. Dorr et
al. recommended the use of anatomical landmarks at the time of surgery to
avoid this problem2.
Others have recommended the use of computer-assisted navigation as a method to
ensure proper acetabular component
alignment3. Asayama
et al. assessed intraoperative pelvic motion during total hip arthroplasty
with use of a pelvic tilt goniometer that was composed of . . . [Full Text of this Article]
