FUNCTIONAL OUTCOME OF CERAMIC ON CERAMIC TOTAL HIP REPLACEMENT USING A 36 MM DIAMETER FEMORAL HEAD

Dr Parveen Kumar Thakur, Dr Naveen Gupta

Abstract :

Background & Objectives: Pain in the hip joint is one of the most important causes in disabling human locomotion. Total hip arthroplasty represents the greatest single advance in modern orthopaedic surgery. The size of the femur head and the be� surfaces to be used, have always been a subject of concern in the THR. The present study was conducted to study functional outcome of a ceramic on ceramic total hip arthroplasty using a 36 mm femur head. Method: In this study 30 patients of 30 diseased hips, aged between 30 and 75 years, who were treated with ceramic on ceramic total hip replacement were studied for 18 months durations. To assess the functional outcome of study pre-op HHS (Modified Harris Hip Score)[1] and WOMAC (Western Ontario &McMaster Universities Osteoarthritis index)[2] was compared to the post op HHS and WOMAC score at 12 months and 18 months. Results: In this study we observed HHS Modified) excellent results in 17 hips and good result in 13 hips. No fair or poor results were noted. The mean Western Ontario & McMaster Universities Osteoarthritis index showed a significant decrease in the score (Higher scores on the WOMAC indicate more pain, stiffness and functional limitations) from 70.5 to 14.8 at 12 months and 14.2 at 18 months. Conclusion: This study shows that a ceramic on ceramic be� THR using a 36 mm diameter femur head has excellent to good result. Long term studies are necessary to study the late complications and to prove the efficacy of the implants and procedure.
