ABSTRACT:
The stem of the femoral prosthesis is provided with a slot in the medial narrow side which communicates with a through-bore within the stem adjacent to the collar. In addition, an elastomeric filling is disposed within the through-bore and cooperates with an arch which connects the proximal end of the stem to the collar or neck in order to adapt the resilience of the stem in the proximal zone to the resilience of the cortical bone. The filling may be made of polyurethane or silicone material.
