title: Revisional total hip replacement for failed ring arthroplasty.
abstract: In a series of 1,219 uncemented Ring total hip replacements performed over an eleven-year period, ten prostheses had to be removed, mainly because of infection, and eighty-two had to be revised, mainly because of loosening. At an average of three years after revision, 81 per cent of the reoperations had yielded satisfactory results.
