Cup–Cage Solution for Pelvic Discontinuity

Abstract

The cup-cage reconstruction is indicated in massive acetabular bone loss with or without pelvic discontinuity during revision hip arthroplasty. We report the results of 26 pelvic discontinuities treated by this technique at a mean follow up of 46.6 months. The average Harris hip score was 76.6. Three constructs failed all within the first postoperative year. Complications included one deep infection, two dislocations and one peroneal neuropathy. Cup-cage construct is a reliable technique for treating pelvic discontinuity in mid-term follow-up.
