Resurfacing for Perthes disease: an alternative to standard hip arthroplasty.
Metal-on-metal total hip resurfacing is an alternative to conventional total hip arthroplasty with several reports describing the benefits of this procedure in young patients. We retrospectively compared the clinical (including range-of-motion and leg length restoration) and radiographic outcome of resurfacing in young patients with Legg-Calvé-Perthes to those of patients of a similar age treated with a standard total hip arthroplasty. Eighteen patients (19 hip resurfacings) who had a mean age of 33 years (range, 18-34 years) were followed for a minimum of 26 months (mean, 51 months; range, 26-72 months). We used an anterolateral approach in four hips and a posterior approach with a trochanteric advancement in 15 hips. Eighteen of the 19 hips had Harris hip scores greater than 80 points at final followup. All patients improved range of motion while avoiding any clinically apparent impingement. Leg length was gained in 16 hips where preoperative measurements were available. The short-term results of hip resurfacing for the treatment of Perthes disease compare similarly to those found in the literature for standard total hip arthroplasty in young patients. The trochanteric advancement technique described may aid in treating the deformed femoral anatomy.
