Bone remodelling along a titanium hip arthroplasty stem after resection of a chondrosarcoma.
Long-term anchorage of cementless total hip arthroplasty relies on a direct bone to implant bonding. Several factors including material properties and surface treatment determine the interfacial response of the host bone to a foreign material. In the case presented, a chondrosarcoma of the proximal femur required an extended extraperiosteal resection. Reconstruction was possible with a titanium-alloy revision stem. A bony remodelling of the proximal femur was observed along the surface of the stem.
