摘要：

This retrospective study reports the 4- to 6-year results of clinical and radiologic follow-up of 60 acetabular revisions using extra-large hemispherical press-fit cups without additional screw fixation. Bone grafts were used in 17 cases. One cup loosened and required re-revision after 12 months. Initial migration was noted in 6 cases, but showed no progression after less than 2 years. in 2 hips that were revised for deep infection, the cups were found incorporated. At final followup, 57 hips (95%) were found firmly fixed radiologically. The Harris Hip score improved from a mean of 58.7 points preoperatively to 90.6 points. Provided a high friction coefficient is present, extra-large hemispherical cups offer sufficient stability even in severe cases. Most do not require additional screw fixation.
