Abstract

Revision total hip replacement has high rates of failure, which appear to be due in part to deficient bone stock that does not provide an adequate environment for implant fixation. We reviewed the clinical outcomes and implant stability following total hip revisions using the S-ROM implant. Between 1996 to 2001, we performed 62 cementless revision hip arthroplasties using the S-ROM prosthesis. Data on 54 patients were available for study, with a mean follow-up of 4.5 years (range, 4–6 years). Radiological analysis, patient satisfaction and Harris hip scores were assessed pre- and postoperatively. Overall, 85% of patients were satisfied with the results of surgery. Harris hip scores improved from a preoperative value of 40 to 80 points at the last available follow-up. 52 stems (96%) were radiologically stable on the final follow-up. Two had marked initial subsidence, but this later stabilised. There was no re-revision due to loosening. With improvement of the postoperative hip score by more than 40 points and absence of definite implant instability and re-revision at the final follow-up, the use of S-ROM prosthesis in the revision cases of this study seems to have been successful.
