Changes in Femoral Version During Implantation of Anatomic Stems: Implications on Stem Design.

Background: Component positioning in total hip arthroplasty (THA) is among the primary indicators for longevity and success. Acetabular component positioning has been discussed in literature at length; however, femoral component positioning is also important as it contributes to combined anteversion.

Methods: In this study, we examined the changes in femoral anteversion after the implantation of anatomic stem ABG II.
