The use of proximal femoral allografts in revision total hip arthroplasty.
The implant of a proximal femoral structural allograft is one of the possibilities to restore circumferential defects of multiply revised total hip arthroplasties. A review of 7 patients who underwent proximal femoral reconstruction with an allograft-prosthesis composite to restore bone loss in revision hip replacements is presented. The average follow-up period was 50.2 months. Two patients developed an infection and in one case an instability of the prosthesis appeared. Incorporation in the remaining 5 cases was/achieved in an average period of 8.2 months. Neither fractures nor high rate of resorption appeared in our series. The majority of patients have improved in the functional assessment. Despite the rate of complications, structural femoral allografts can be used with success in this difficult challenge of reconstructing major segmental bone loss of the proximal femur in revision hip surgery.
