Assessment of Outcome Measures of Bipolar Hip Arthroplasty for Atraumatic Hip Disorders: A Clinical Study
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2018, Vol 6, Issue 6
Abstract
Background: The bipolar hip arthroplasty was originally proposed for femur neck fracture in aged patients. Gradually, indications were implied for conditions involving acetabulum like osteoarthritis rheumatoid arthritis, and even avascular necrosis of the femoral head. Materials and methods: Study was conducted in 25 such patients who were diagnosed of bipolar hip arthroplasty, which involved acetabulum. That may be because of primary osteoarthritis, rheumatoid arthritis, avascular necrosis of the femoral head. A tight 'equatorial' or 'rim' fit of the prosthesis were devised for acetabulum. A 1 mm larger prosthesis was selected with respect to the maximum size of reamer to be used. Accordingly, in case of marked osteoporosis or wide medullary canal cement was used in the femur. During the post-operative follow-up all patients were screened for post-operative pain, extent of movement, protrusion of the acetabulum, loosening of the prosthesis and radiographic evaluation of the movement in the two bearings of the prosthesis. Results: On an average, results so achieved ranged from good to excellent in 75% of the patients. Conclusion: The overall satisfactory results achieved and are comparable to complete hip arthroplasty. The procedure is low cost, simple and easy for future corrections.
