Patent ID: 6974482

Claim:
A prosthetic femoral hip stem, comprising: a metal core having an elongated body extending from a proximal portion to a distal portion, the distal portion adapted to be inserted into an intramedullary canal of a patient; and a proximal body connected to the proximal portion, the proximal body having a distal end surface and a proximal end surface, and wherein the proximal body completely surrounds the metal core between the distal end surface and the proximal end surface, the proximal body being formed entirely of polymer and having an external surface adapted to engage bone in the intramedullary canal, wherein the external surface is textured such that the external surface has a multitude of pores adapted to induce growth of cancellous and cortical bone into the external surface, and further wherein the external surface of the proximal body is configured and arranged to make direct contact with the cancellous and cortical bone without cement between the bone and the external surface of the proximal body, and still further wherein the external surface has a textured thickness from about 0.05 mm to about 5 mm.
