Focal lytic lesions may occur in the proximal femur associated with loosening of the femoral component of a total hip prosthesis. During long-term follow-up of 62 patients with total hip prostheses, five such lesions developed. Histologically the lesions appear to be a histiocytic response to fragmented methylmethacrylate. Radiographically the lesions may suggest infection or neoplasm. Pathologic fracture may occur through large lesions. Experience in one case suggests that thorough removal of the tissue at the time of revision may be necessary to prevent recurrence. The recent reports of several malignant neoplasms developing in association with the femoral components of total hip replacements makes recognition of these benign focal lytic lesions even more important.
