A clinical study to evaluate the effectiveness of primary total hip arthroplasty in various disorders of hip

Abstract

Background and Objectives:Total hip arthroplasty (T.H.A) remains one of the most frequently performed reconstructive surgeries. Much work has been done in this discipline over the past years with regards to scientific investigation, clinical outcome assessment, and the treatment of complications. The short term results of THR for nonunion, AVN and failure of internal fixation of femoral neck fractures have been uniformly good.Methods: Between July 2017 and June 2019, 18 patients with various disorders of the hip got admitted in Department of Orthopaedics, Saraswati Medical College, Unnao,U.P.,India. They were subjected to primary cemented THR and the functional outcome was evaluated using Harris hip score. Results:20 hips were operated in 18 patients for Avascular Necrosis (8 patients), Fracture Neck of Femur (7 patients), Ankylosing Spondylitis (3 patients), Rheumatoid Arthritis and Osteoarthritis (1 patient each). Harris hip score was used for evaluation of functional outcome which was on an average 34.6 (16-53) preoperatively and 87.9 (45.5-97) postoperatively. We had complications in 2 patients, acetabular perforation was seen in 1 patient and acetabular cup migration was seen in another. We had good to excellent results in 88% of patients. Average follow-up was of 11 months in our study. Conclusion: The patient sample approximately reflected the regular cases of hip pathologies encountered in our setup. At present it can be interpreted that in properly selected cases, cemented THA offers a better alternative procedure for various hip joint pathologies in the elderly. We also confirmed the proven efficacy of THR in treatment of racture neck of femur in elderly patients.
