Hip osteotomy arthroplasty: ten-year follow-up.
We previously reported the initial success of combined osteotomy and arthroplasty of the hip for arthritis with femoral deformity. This technique has gained acceptance. We now report, for the first time, the ten year clinical and radiographic results with histology of 2 specimen. The osteotomies healed and the proximal femoral segment remained viable. One of three patients is symptom free without subsequent operative treatment. One of three patients had revision for acetabular loosening at eight years and biopsy of the proximal femur showed the proximal femoral segment to be viable. One of three patients had loosening of a macrofit bipolar prosthesis which required revision to total hip replacement at five years. Histology revealed viability of the proximal femur. All three patients are doing well at ten year follow-up. Based on the results of this study and current knowledge, the technique of osteotomy and arthroplasty for hip arthritis associated with femoral deformity is effective when combined with current techniques of ingrowth femoral component of total hip arthroplasty.
