Abstract
A system and method for trialing a modular hip replacement system permits evaluation and replication of the anatomic anteversion rotational angle of the femur. In one embodiment, a femoral hip implant kit includes at least one distal implant and a plurality of femoral heads, each of the plurality of femoral heads having a diameter different from the diameter of the other of the plurality of femoral heads. The kit includes a proximal trial housing with a bore within the housing, the bore configured to receive a portion of the distal implant, a collet located within the bore, the collet including an outer wall portion extending between a top surface portion and a bottom surface portion, a collapsing member for engaging the portion of the distal implant and for forcing the top surface portion of the collet toward the bottom surface portion of the collet along a first axis.
