Abstract:
PURPOSE: The authors evaluated the clinical and radiological results of ceramic on ceramic articulation cementless total hip arthroplasty using a large diameter head. MATERIALS AND METHODS: Seventy-two hips were followed for more than 2 years after ceramic on ceramic articulation cementless total hip arthroplasty using a 36 mm diameter head. The mean patient age was 62 years (range: 50-85), and the mean follow-up period was 35.3 months (range: 25-53). The Harris hip score, the postoperative inguinal pain and the thigh pain were analyzed clinically. The radiological results were assessed using various radiological indices. RESULTS: The mean Harris hip score improved from preoperative 57.5 points to postoperative 94.8 points. The postoperative mean flexion of hip was 109degrees (range: 100degrees-125degrees), external rotation was 42degrees (range: 35degrees-49degrees) and abduction was 35degrees (range: 30degrees-45degrees). There was one case of inguinal pain. Radiologically, all the stems demonstrated stable fixation without progressive subsidence of the stem or significant change in the cup obliquity. A radiolucent line was observed around the stem in 4 cases (5.6%) and around the cup in 2 cases (2.8%). Endosteal new bone formation was observed around the stem in 28 cases (38.9%) and around the cup in 26 cases (36.1%). There was no osteolysis around the stem or the cup. CONCLUSION: The short-term results of ceramic on ceramic cementless total hip arthroplasty using a large diameter head demonstrated satisfactory results.
