Femoral revision with impaction allografting and an uncemented femoral component.
A technique for uncemented revision of the femoral component which combines impaction allografting and the use of a long-stemmed proximally coated titanium prostheses (Bimetric, Biomet Inc.) is described. The results after a mean follow-up of 112 months are reported. From 1991 to 1995 femoral component revision for aseptic loosening was performed on 100 hips. In 14 cases (14%) an intraoperative fracture occurred and 7 patients (7%) had other postoperative complications. Seventeen patients (17%) required further revision, 10 because of aseptic loosening. Of 50 surviving patients with retained implants 88% had no pain, 10% had slight pain and only 2% had severe pain. Thirty-eight patients had radiographic signs of remodelling of the graft and/or cortical repair. In cases with a successful outcome, the results have been encouraging in relation to clinical performance, regeneration of bone and implant survival.
