Abstract
We report experience of 207 consecutive metal on metal hip resurfacings in 179 patients, implanted by one surgeon since January 2002. The mean age at operation was 56 years (35 – 78 years) and follow-up ranged from 12 to 84 months (mean 39 months). The gender mix was 2:1 M: F. The Birmingham Hip Resurfacing was implanted in the first 155 cases with a switch to Finsbury Adept Hip Resurfacing for the remaining 52 cases.
Data was obtained on all but one patient. There were four unrelated deaths (1.9%). No primary infections and no femoral neck fractures were encountered. One secondary infection at five years was salvaged by surgery and antibiotic treatment (0.5%). One male suffered a pertrochanteric fracture as a result of significant violence 15 months after operation (0.5%). Dislocation in five cases was the commonest complication encountered (2.4%). One of these cases developed recurrent dislocation and underwent early revision to a constrained total hip replacement (0.5%). This was the only failure in the series and no further revisions are pending.
Our survivorship results compare very favourably with outcomes reported from centres of excellence and far exceed the survivorship estimates published by the National Joint Registry.
