Abstract:
An enhanced range-of-motion femoral prosthesis, comprising:a stem having a distal portion adapted for placement within an intramedullary canal, a proximal end, and longitudinal stem axis ""s"";a head configured to co-act with a corresponding acetabular component; anda neck connecting the head to the proximal end of the stem, the neck having a first segment with a longitudinal axis n.sub.1 where the neck connects to the stem, and a second segment with a longitudinal axis n.sub.2 where the neck connects to the head, wherein n.sub.1 forms an angle a.sub.1 with s, and n.sub.2 forms an angle a.sub.2 with s, and a.sub.2 is greater than a.sub.1 to reduce impingement of the neck on the acetabular component.
