ABSTRACT:
A femoral head prosthesis is provided with a slot which extends from ventral to dorsal within the distal zone of the stem to separate a tongue-like core from a resilient peripheral portion. The tongue-like core is able to move in the slot in response to bending and twisting stresses. The shear forces which these stresses produce in a transition zone between the bone and the stem are thus, at least, reduced. The slot may be of U-shape with arms parallel to the sides of the stem or with arms parallel to the axis of the stem. One arm of the slot may also be shorter than the other and one arm may be of widening shape relative to the other.
