Use of a modular femoral component in total hip arthroplasty effectively treated osteoarthritis in patients with Legg-Calve-Perthes disease, according to study results.
Between July 1997 and December 2012, researchers performed 35 consecutive total hip arthroplasties (THAs) using a non-cemented modular femoral component in 28 patients with Legg-Calve-Perthes disease.
Results showed an improvement in Harris Hip Scores from 49.8 preoperatively to 93.9 at follow-up. Researchers also found 94.3% of hips demonstrated diminished or no limping at follow-up. In 80% of hips, metaphyseal mismatch was corrected with the modular stem. Overall, researchers found one re-operation for deep hemotogenous infection at 3 years and 10 months postoperatively. Radiographic data showed no statistical change in the abductor lever arm postoperatively. However, body weight lever arm and trochanteric height were significantly decreased, according to study results. In an analysis of 14 hips with available preoperative radiographs, researchers noted leg length was equal in 11 of 14 hips and improved by 20 mm, 20 mm and 31 mm in the remaining three hips. According to postoperative analysis, all THA were ingrown without osteolysis. – by Casey Tingle
