Abstract:
Various types of hip lesion associated with long-term haemodialysis have been observed. We present a new radiological classification system of haemodialysis-related hip arthropathy. In total, 103 hip lesions were analyzed in 84 patients undergoing haemodialysis for more than ten years. The hip lesions were classified into 3 types; Type I--cystic type with further subdivisions based on cyst location, Type II--arthritic type, and Type III--deformity of the femoral head. Surgery was performed on 60 hips. We believe our classification system assists decision making on behalf of these patients.
