EARLY RESULTS OF THE BIRMINGHAM HIP RESURFACING: PROSPECTIVE REVIEW OF 231 CASES AT A MEAN OF 3 YEARS

We describe our early experience with the implantation of the first consecutive 231 primary Birmingham Hip resurfacings. At a mean follow up of 33 months, survivorship was 99.14 %, with revision in one patient for a loose acetabular component and one unrelated death. Mean Harris Hip score improved from a mean of 62.54 ( Range : 8–92) to 97.74. (Range: 61 – 100) Mean flexion improved from a mean of 91.52°, ( Range : 25° –140°) to a mean 110.41°. ( Range : 80° – 145°) 1 patient presented at 6 weeks post resurfacing with pain and no history of trauma. An undisplaced fracture of the superior femoral neck was seen, which healed with a period of non-weight bearing. 96.94% of patients rated their prosthesis as good / excellent, the remainder rated it good/fair.
