A trial () for use in performing joint arthroplasty is provided. The trial () fits to a cavity () in the canal () of a long bone () and assists in the performing of a trial reduction in performing joint arthroplasty. The trial () includes a stem portion () and a neck portion () fixedly connected to the stem portion () in a plurality of selectable positions with respect to the stem portion ().

Instrument and associated method of trialing for modular hip stems

Instrument and associated method of trailing for modular hip stems

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