CIRCUMFERENTIAL PROXIMAL FEMORAL ALLOGRAFTS IN REVISION SURGERY ON TOTAL HIP ARTHROPLASTY: CASE REPORTS WITH A MINIMUM FOLLOW-UP OF 20 YEARS.

Among the options for femoral reconstruction in total hip arthroplasty (THA) revision procedures, in cases of extensive circumferential defects, is the use of proximal femoral allografts. This technique makes it possible to correct the hip abductor mechanism and the leg length discrepancy, as well as presenting osteoconductive potential. The authors report the clinical and radiographic results from two cases of THA revision using this technique, with a minimum follow-up of 20 years.
