“…[4][5][6][7] Failure has generally resulted from excessive wear because of the necessarily large diameter of the femoral head. Design, fixation and bearing performance are all interrelated.…”

We report the survival at five years of 144 consecutive metal-on-metal resurfacings of the hip implanted between August 1997 and May 1998. Failure was defined as revision of either the acetabular or femoral component for any reason during the study period. The survival at the end of five years was 98% overall and 99% for aseptic revisions only. The mean age of the patients at implantation was 52.1 years. Three femoral components failed during the first two years, two were infected and one fractured. A single stage revision was carried out in each case. No other revisions were performed or are impending. No patients were lost to follow-up. Four died from unrelated causes during the study period. This study confirms that hip resurfacing using a metal-on-metal bearing of known provenance can provide a solution in the medium term for the younger more active adult who requires surgical intervention for hip disease.

“…1 In the 1970s, total resurfacing hip arthroplasty using a polyethylene cup and a metal head gained in popularity. [2][3][4][5][6][7][8] However, high rates of failure resulted in the procedure being abandoned. 9 It is established that, for most designs of implant, the main threat to longterm fixation is debris from polyethylene bearings.…”

The Birmingham hip resurfacing metal-on-metal arthroplasty was introduced in 1997 and has shown promising short- to mid-term results. We used radiostereophotogrammetric analysis (RSA) to study the stability of 20 resurfacing arthroplasties over a follow-up period of 24 months. Radiological examinations for RSA were performed immediately after surgery and at two, six, 12 and 24 months after operation. Precision and detection of migration thresholds (non-zero movement) were calculated. All the results corresponded well to those found in similar experimental arrangements with standard hip prostheses. Migration of the cup and vertical and mediolateral migration of the head were calculated. The values were low at two years compared with those of earlier studies of cemented femoral components in conventional total hip replacements indicating that there was no evidence of excessive early migration or loosening of the components.

“…Previous hip resurfacing implants have used cement and metal-on-polyethylene bearings. [1][2][3] This combination has produced poor results because of the production of polyethylene wear debris and subsequent osteolysis. 4,5 By changing to a metal-on-metal bearing of cobalt-chrome alloy, the issue of polyethylene wear is exchanged for that of metallic ionic debris, whose systemic effects have yet to be defined.…”

We describe the experience with the first consecutive 230 Birmingham hip resurfacings at our centre. At a mean follow-up of three years (25 to 52 months) survivorship was 99.14% with revision in one patient for a loose acetabular component and one death from unrelated causes. One patient developed a fracture of the femoral neck at six weeks which united unremarkably after a period of non-weight-bearing. The Harris hip score improved from a mean of 62.54 (8 to 92) to 97.74 (61 to 100). The mean flexion improved from 91.52 degrees (25 to 140) to 110.41 degrees (80 to 145). Most patients (97%) considered the outcome to be good or excellent. Our preliminary experience with this implant is encouraging and the results are superior to the earlier generation of resurfacings for the same length of follow-up.
