The Combined Anteversion Technique for Acetabular Component Anteversion
Abstract
The combined anteversion technique for acetabular component placement of total hip arthroplasty is beneficial because of the surgeons' limited ability to control the anteversion of a cementless femoral stem. Our data show that the cementless stem anteversion can be 15° different than anticipated. By determining femoral stem anteversion before positioning cup anteversion, the cup anteversion can be adjusted for the stem anteversion. The combined anteversion technique should provide a mean near 35° with a safe zone of 25° to 50°.
Key words: combined anteversion, acetabular component anteversion
