Total Hip Arthroplasty with F2L Multineck Cementless Femoral Stem

ABSTRACT

PURPOSE: To analyze the results of cementless total hip arthroplasty with a F2L Multineck femoral stem. MATERIALS AND METHODS: A total of 64 patients (73 hips), who underwent cementless total hip arthroplasty with a F2L Multineck femoral stem, SPH acetabular cup and a ceramic liner from December of 1998 to October of 2001 were followed up for at least 4 years, were selected for the clinical and radiological evaluations. RESULTS: At the final evaluation, 63 patients had an improved average Harris hip score ranging from 51.4 preoperatively to 95.1. None of the patients had any significant leg length inequality. Thigh or inguinal pain was observed in 3 hips (1 hip of femoral stem subsidence and 2 hips of damaged ceramic parts), for which revision total hip arthroplasty was performed. Hip dislocation occurred in 2 hips within 2 weeks after surgery and conservative management was performed after a closed reduction. CONCLUSION: Total hip arthroplasty with a F2L Multineck femoral stem produced satisfactory results. Postoperative complications such as hip dislocation and leg length inequality could be minimized by modulating the anteversion angle, femoral offset and leg length with multineck femoral stem.
