Impacted corticocancellous allografts and cement for revision of the femur component in total hip arthroplasty

Revision of the femur component in total hip arthroplasty using impacted morcellized bone allografts and cemented Lubinus SP-II prosthesis or Charnley standard prosthesis was performed in patients with loss of bone stock grade II through IV according to the Endo-Klinik classification from 1st to 8th revision. We report the results from 57 hips in 56 patients, with a median of 64 months’ follow-up. Modified Merle d’Aubigne–Postel postoperative scores increased significantly from preoperative to postoperative values for the Lubinus group and for the Charnley group. Few complications were seen in this follow-up period. Five stems had minor subsidence. Rate of mechanical failure was 4% for both groups. Radiologic examinations provided evidence of frequent trabecular remodeling of the graft, especially for the Lubinus prosthesis.
