RESULTS OF REVISION OF HIP-ARTHROPLASTY WITH CEMENT - A 5-YEAR TO 14-YEAR FOLLOW-UP-STUDY

We reviewed the results of sixty revisions of cemented total hip replacement in fifty-four patients who had complete clinical and radiographic follow-up. All of the revisions were performed by a standardized operative technique, in which both components of a single model of prosthesis were fixed with cement. In nineteen of the sixty revisions, autogenous grafts from the iliac crest were used for a deficiency in the roof of the acetabulum. After five to fourteen years, there had been two infections and four additional revisions for aseptic failure. Three cups had migrated, and another seven were surrounded by a complete radiolucent line. Five femoral components had subsided, and another eleven were surrounded by a complete radiolucent line. Survivorship analysis of eighty revisions showed a cumulative survival of about 85 per cent at fourteen years. In these relatively old patients, the outcome of revision of hip replacement with the described operative technique was very satisfactory.
