| Summary points: | The authors present a case of revision acetabulum arthroplasty performed with Birmingham dysplasia acetabular cup, which unfortunately failed within a period of 8 months. Surgical technique appeared to be adequate; however, on further analysis, significant differences were identified between dysplastic hips with bone loss and revision hips with bone loss. The authors discuss how the results obtained with dysplasia cups in resurfacing dysplastic hips does not seem to be applicable to revision hip arthroplasty and recommend these cups should be restricted to primary arthroplasty. |
