title: A minimum of 10-year follow-up of the Burch-Schneider cage and bulk allografts for the revision of pelvic discontinuity.
abstract: Eighteen consecutive hips with pelvic discontinuity and associated periprosthetic bone deficiency were treated with bulk allografts and Burch-Schneider antiprotrusio cage. Clinical and radiographic follow-up was performed at an average of 13.5 (range, 10.5-16.6) years. Three cages required re-revision because of infection (1) and aseptic loosening (2). Average Harris hip score improved from 31.9 to 77.0 points (P < .001). A severe resorption of the bone graft occurred in 2 hips. The stability of the cage was detected in 13 cases. The cumulative survival rate at 16.6 years with acetabular revision for any reason, radiographic loosening, or unhealing of the discontinuity as the end point was 72.2%. The use of Burch-Schneider cage and bulk allografts is an effective technique for the treatment of pelvic discontinuity.
