ABSTRACT:
A canine femoral stem system provides a set of sizes of stems designed to fit in a reamed femoral bone canal with controlled interference. The canine femoral stems can be implanted using either a cemented or cementless procedures. Cementless stems have a porous coating of sintered beads on the tapered proximal section providing interference with reamed femoral canal causing friction and initial stability. The distal end of the stem has a tapered fit and contacts the lower region of the reamed femoral bone canal due to curvature of the stem providing distal stability. The porous coating encourages bone ingrowth in the cementless system or cement penetration resulting in long term stability. The cementless system uses either cast cobalt chromium stems with 250±50 μm beads of cobalt chromium or Ti- 6Al- 4V stem with 250±50 μm beads of chemically pure titanium.
