Calcar collar instrumentation including a calcar collar and a proximal femoral stem. The calcar collar includes a foot with a foot member having a face surface; a back attached to the foot and including a back member having a face surface arranged at an angle to the face surface of the foot member; and attachment structure for removably and adjustably attaching the foot and the back to the proximal femoral stem. The proximal femoral stem includes one or more necks for allowing the calcar collar to be snapped thereto.

Instrumentation for positioning a cut guide to cut a posterior slope in the tibial plateau surface of a tibia. The instrumentation includes an intramedullary alignment guide for engaging the tibia, and a rotational alignment guide for providing a guide for the insertion of a rod portion of the intramedullary alignment guide into an intramedullary bore in the tibia with the intramedullary alignment guide rotationally aligned with the intramedullary bore so that the longitudinal axis of a handle portion of the intramedullary alignment guide is angled posteriorly with respect to the longitudinal axis of the rod portion and the longitudinal axis of the intramedullary bore as the rod portion of the intramedullary alignment guide is inserted into the intramedullary bore.

A trapezial implant is provided for attachment to the trapezium of a hand. The implant includes a base member fabricated from an inelastic material such a medical grade metal or ceramic. The base member includes a generally planar proximal attachment surface from which extend two pentihedral-shaped spikes. The base member also includes a distal articular surface having a non-symmetrical, complex curvature. The implant is retained in place on the trapezium under compression of the first metacarpal.
