Claim:
A femoral hip implant kit comprising: at least one distal implant; 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; a proximal trial housing; a bore within the housing, the bore configured to receive a portion of the at least one distal implant; a collet within the bore, the collet including an outer wall portion, an upper portion and a bottom portion; and a collapsing member for engaging the portion of the distal implant and for forcing the upper portion of the collet toward the bottom portion of the collet along a first axis when movement of the bottom portion along the first axis is constrained, thereby moving the upper portion of the collet toward the bottom portion of the collet so as to force the outer wall portion in a direction generally perpendicular to the first axis such that the outer wall portion is located outwardly of the upper portion and the bottom portion with respect to the first axis, wherein the collet has a generally arced cross section, and wherein the collet is integrally formed with the collapsing member.
