[The use of Müller acetabular rings in revision surgery of total hip prosthesis. Apropos of 141 cases with a minimal 5-year follow-up].
211 acetabular reinforcement rings of Müller have been implanted when revising total hip arthroplasties, 141 were followed up for more than 5 years. In 52 per cent of cases, an acetabular reconstruction using bone grafts was associated: in 51 cases, a bank allograft was used, one third of the grafts had only a role of filling. Theses rings remained remarkably stable and there were only 2 lacks of fixation: 1.4 per cent in cases non grafted. They allowed a quick weight bearing while warranting stabilisation and protection of the grafts and recentering the hip. So their use has become systematic in THR revisions except for stage IV acetabular loosenings in which the osteosynthesis of the acetabular transverse fracture can be preferred.
