AMYLOID BONE-CYSTS OF THE FEMORAL-NECK - IMPENDING FRACTURES TREATED BY CURETTAGE AND BONE-GRAFTING

We performed curettage and bone grafting of amyloid cysts of the femor al neck in five patients on long-term haemodialysis. All had had hip p ain on weight-bearing. The duration of haemodialysis before the operat ion averaged 15 years and the average age of the patients was 53 years . All the large cystic lesions were located in the anterosuperior quad rant of the femoral neck At operation, they were found to consist of f ibrous tissue containing amyloid deposits. Postoperatively, all five p atients had painless hips and the grafts had incorporated into the bon e defects.
