| Popis: | 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 t o 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. |
