Abstract
Sleeve for affixing artificial joints to bone are provided which include a cone-shaped portion centered on the sleeve's longitudinal axis and a protruding portion offset from the longitudinal axis having an elliptically-shaped leading edge. Cavities which are essentially a perfect match to the shape of the sleeve can be readily formed in the patient's bone. The shape of the cavities generally correspond to the inside shape of the patient's hard bone. Accordingly, when implanted, the sleeves transfer stresses from the prosthesis to hard bone as is desired.
