Fractured femoral shaft through an osteolytic lesion resulting from the reaction to a prosthesis. A case report.

This paper reports a singular case of pathological fracture through a large osteolytic lesion of the mid-femur consequent on reaction to a hip prosthesis. Not only metal particles but also polyethylene fibres were found at this site, some 15 cm from the prosthesis. The case sheds an interesting light on the reaction to prostheses.
