  • Title: Proximal femoral allografts for bone deficiencies in revision hip arthroplasty: a medium-term follow-up study.
    Author: Wang JW, Wang CJ.
    Journal: J Arthroplasty; 2004 Oct; 19(7):845-52. PubMed ID: 15483799.
    Abstract:
    Fifteen patients who had undergone hip reconstruction using a proximal femoral allograft-prosthesis composite because of failed total hip arthroplasty were reviewed retrospectively. The average length of allograft was 11 cm. The average follow-up period was 7.6 years. Ten patients retained the allograft-prosthesis construct, yielding a success rate of 67% for the procedure. The average preoperative Harris Hip Score of all patients was 21.7 points. At the latest follow-up, the average hip score for 10 patients with retained allograft-prosthesis composite was 81 points. Complications included junction nonunion (13%), allograft fracture (6.7%), loosening of acetabular component (6.7%), trochanteric escape (26.7%), allograft infection (20%), and allograft resorption (20%). Although proximal femoral allograft-prosthesis composite achieved good clinical results in most of the patients at medium-term follow-up, the late development of infection and resorption of the allograft warranted continued observation of patients who had undergone such procedures.
