Revision hip arthroplasty using strut allografts and fully porous-coated stems.

At a minimum of 10 years after surgery, we prospectively evaluated the clinical and radiographic outcomes of revision total hip arthroplasties using cortical strut allografts and fully porous-coated cementless revision femoral components in patients with massive femoral bone deficiency. There were 21 men and 33 women (54 hips) in the series, with patients' mean age at the time of index revision being 54.6 years (range, 36 to 65 years). All femurs had 2 or 3 fresh-frozen femoral strut allografts. The Harris hip score improved from a mean of 21 points before revision surgery to a mean of 83 points at the latest case review. Two femoral stems (4%) had aseptic loosening and were revised. All allografts were predictably united to the host femur. On the basis of favorable results at a mean follow-up of 10.5 years, we recommend, as a salvage procedure, the use of fully porous-coated cementless femoral stems and strut allografts in revision surgery of the hip for massive femoral bone loss.
