Between October 1992 and December 1996, 23 patients with pelvic bone stock deficiency involving major columns underwent revision surgery with a cementless press-fit cup and a structural bone graft. Twenty cases were followed up for a minimum of 6 (average 7.6, range 6-11) years. Three cups were revised: one for aseptic loosening, one for septic loosening, and one for recurrent dislocation. At latest follow-up, the average Merle d'Aubigne hip score improved from 10.9 to 16.2; four hips were rated excellent, seven very good, three good, two fair, and one poor. All cups were stable; the grafts were integrated and anatomy was restored. The Kaplan-Meier cumulative probability of not having revision for loosening at 11 years, predicted a survival rate of 84.4%. We are confident that these results are satisfactory for a very demanding procedure.
