RESUMO

PURPOSE: This study examined the effect of a varus positioned femoral stem after cementless proximal fitting total hip arthroplasty. MATERIALS AND METHODS: A total of 144 hips in 136 patients who underwent cementless total hip arthroplasty, were followed-up. Twenty-one varus positioned hips were compared with 123 neutral positioned hips. The clinical results were analyzed according to the level of thigh pain and the Harris Hip score. The radiological outcome was assessed according to osteolysis, loosening and stem failure. RESULTS: In the varus positioned hips, thigh pain was present in 1 hip, and the average Harris Hip Score was 96 points. None of the implants showed radiological evidence of loosening or impending failure. Localized osteolysis was identified in 1 hip, non-progressive radiolucencies in 2 hips, and cortical hypertrophy in 1 hip. In the neutral positioned hips, thigh pain was present in 6 hips, and the average Harris Hip Score was 97 points. Localized osteolysis was identified in 8 hips, non-progressive radiolucencies in 7 hips, cortical hypertrophy in 9 hips. CONCLUSION: Patients with varus alignment of the stem did not present poorer clinical outcomes than those with neutral alignment of the stem.
