Hip arthroplasty in chronic dialysis patients.
We retrospectively reviewed 15 patients (24 hips) on chronic renal dialysis who underwent hip arthroplasty between 1970 and 1990. The average age at surgery was 39 years; the average follow-up was 8 years (range, 1-19 years). All follow-up of less than 5 years relates to those patients who died. Of these 24 hips, 14 (58%) failed or were failing due to loosening; the average time to revision was 7 years (range, 1.5-14 years). A complicated course was experienced in 16 hips (66%), primarily related to medical difficulties. There was one perioperative death. The following orthopedic complications afflicted 5 hips (21%): one femur fracture during revision; one femur fracture at 2 months after revision; one dislocation during seizure; one displacement of acetabular cup requiring recementing; and late generalized septic death of one patient (with both hips involved). Within an average of 3 years (range, 15 months to 7 years) after their index surgery, 6 of the 15 patients (40%) died. The patients who lived were chronically ill, and all but three remained on long-term dialysis. The functional level of all those remaining on dialysis steadily declined, and none reached a quality of life comparable to an osteoarthritic patient. This study confirms a previously reported high mortality and morbidity rate in this population. Despite their difficulties, 22/24 primary hips were relieved of pain and increased in function; six patients returned to work. We see no better alternative for pain relief in total hip arthroplasty, particularly in view of contemporary surgical techniques and improved medical management.
