Abstract:
PURPOSE: To study the early follow-up results of total hip arthroplasty using a 36 mm large femoral head MATERIALS AND METHODS: Sixteen of primary case and two of revision, who underwent total hip arthroplasty using a 36 mm Cobalt-Chrome femoral head with Longevity(R) (Zimmer , Warsaw, Indiana) as a polyethylene liner from August 2004 to April 2005, were evaluated. The average age was 53 years, and the mean follow-up period was 28.3 months(range, 24 to 32 months). The clinical outcome was analyzed, and the latest follow-up radiographs were assessed to determine the complications such as osteolysis, loosening, fracture, dislocation, etc. RESULTS: There were no complications such as infection and dislocation during the follow-up period. The Modified Harris Hip Scores was more than 'Good'in all cases with a mean score of 93. The Merle d' Aubigne and Postel scores was more than 'Good'in 78%. The radiographic examinations showed satisfactory fixation in all patients with uncemented and uncemented femoral components. There were no cases of osteolysis, loosening, dislocation, and fracture in the pelvis or proximal femur. CONCLUSION: No dislocation was encountered despite there being no limitation in the range of motion in the early post-operative period. Total hip arthroplasty using a large femoral head gave a higher satisfaction to the patients.
