Abstract:
1. An implantable prosthetic device for attachment to a terminal bone end comprising: a stem having first and second ends, the first end for attachment to the terminal bone end, wherein the first end is configured to be introduced into intramedullary bone space, wherein the first end further comprises holes to promote bone ingrowth; a support bracket comprising a housing having a proximal end and a distal end with a hollow interior therein, a bore at the proximal end for receiving the second end of the stem, and a lip at the distal end; and a resilient support fixedly attached to the hollow interior and extending from the distal end of the support bracket to cover at least the lip at the distal end, wherein the resilient support comprises distinct layers of semi-solid elastic material, wherein a first layer is secured at least partially to the hollow interior of the housing, further comprising additional layers that are progressively less dense towards the distal end of the support bracket, wherein the layers of the resilient support comprise material of different durometers.
