title: Pinnacle revision cup in acetabular surgery results at 2 to 5 years.
abstract: Uncemented revision cups are widely used in revision hip arthroplasty; they have shown good results. We report the the short term outcome with the cementless Pinnacle revision cup. All acetabular revisions using a Pinnacle revision cup between January 2007 and March 2010 were included. In March 2012, clinical scores were determined and the latest radiographs were assessed. Revision and radiographic signs of loosening were reported as failure of the cup. Ths study included 117 patients (118 revision cups) with a follow-up between two and five years. Five cups failed (4%). The median modified Harris Hip Score was 64 (range : 18-91). Survival rates of the Pinnacle revision cup are good in the short term follow-up. This implant appears as a safe and reliable solution for small to moderate acetabular defects.
