Clinical and radiological outcome evaluation of large diameter head in uncemented total hip arthroplasty

Introduction: Total hip arthroplasty has been in constant change since its inception. Polymethylmethacrylate, a bone cement introduced by Haboush as a mecahanism for achieving rigid initial fixation have lost its popularity due to problems of loosening of stem and cup. Objective: Evaluation the clinical and radiological outcome of uncemented large diameter head in total hip arthroplasty. Materials and Method: Out of twenty five hips, twenty four patients were operated upon for large diameter head in total hip arthroplasty in the Department of Orthopedics, Pt. B.D.S. P.G.I.M.S. Rohtak. Results: The cases studied included patients from age of 21 years to 60 years with an average age of 40.5 years. 14 cases (58.33%) had avascular necrosis of head of femur, 5 cases (20.83%) had osteoarthritis, one patient had rheumatoid arthritis. 15 patients (60%) were operated on left side, while 8 (32%) were operated on right side and 1 (8%) case was operated on both sides. Metal-on-metal THR was done in 8 cases (32%), Metal-on-polyethylene THR was done in 17 cases (68%) and Ceramic-onceramic was done in none. Postoperative pain was absent in 15 patients (60%), mild pain was seen in 9 patients (36%) and moderate pain in one patient (4%). Conclusion: Total hip arthroplasty continues to be an ideal procedure for achieving painless, mobile, stable hip in cases with advanced hip disorders.
