Hip Joint Diseases in Hemodialysis Patients.

Over a 5 year period (1992-1997), we treated 13 hip joints in 11 patients who had been undergoing hemodialysis for chronic renal failure. The average follow-up period was 3.1 years. The mean post-operative JOA score was 70.9 points.We classified 8 cases of femoral neck fracture into 2 groups; a trauma group and a group with no history of significant trauma. 5 out of 8 cases showed large bone cysts in the femoral neck and head. 4 out of 5 cases (large bone cysts in the femoral neck and head) had no trauma, and we performed prosthetic hemiarthroplasty in these cases.Treatment by curettage and bone grafting of the cysts of the femoral neck was assumed to be difficult. Conseguently when we discovered cystic lesions in the femoral neck and head of patients who had been undergoing hemodialysis, we followed up their subsequent history and performed prosthetic hemiarthroplasty after fracture.
