ABSTRACT:
A system and method for trialing a modular hip replacement system (10) permits evaluation and replication of the anatomic anteversion rotational angle of the femur. A distal stem component (18) of the hip replacement system (10) includes a proximal portion (34) having a locator feature (35) that is externally accessible when the stem component is mounted within the femur. A proximal trial body assembly (60) is mounted on the proximal portion (34) of the distal stem component (18) to permit rotation of a trial neck component (62). The trial neck component (62) also includes a locator feature(126) that can be externally referenced to determine the anteversion angle.
