Biomechanical Analysis of Femoral Range of Motion Following Total Hip Arthroplasty

Femoral range of motion (ROM), described as the attainable degree of flexion prior to impingement, can be reduced following total hip arthroplasty, causing impingement of the femoral and acetabular components during normal physiological motion. This impingement has been associated with the dislocation of the femoral component, abnormal wear of the femoral and acetabular components, and early device failure. This study examines the role of implant size, orientation, and position in relation to the attainable femoral ROM using reconstructed cadaver CT data.
