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.
