PRIMARY TOTAL HIP ARTHROPLASTY VERSUS HEMIARTHROPLASTY FOR DISPLACED NECK FEMUR FRACTURES IN OLDER PATIENTS

Objective: This study was conducted to make a comparative analysis and evaluate the outcomes of fracture neck femur in old age managed with hemiarthroplasty versus total hip arthroplasty. Methods: In this prospective as well as retrospective study. 33 patients were treated with total hip replacement and 36 patients with hemiarthroplasty. Pain, range of motion, hip function, and complications were assessed clinically while hip stability, femoral anteversion, acetabular cup inclination and acetabular erosion were assessed radio graphically. Results: 69 cases were operated with a follow period of 6 months to 2.1 years and average of 1.2 years. In this study, according to Harris hip score, group A (hemiarthroplasty group) showed 58.33% excellent to good result whereas 33.34% had fair to poor result. In group В (total hip replacement group) 90.91% had excellent to good result and 9.08% had fair to poor result. The overall Harris hip score was 76.33 with SD±19.091 in hemiarthroplasty group and 86.45 with SD±6.363 in Total hip replacement group with p-value 0.0224 (<0.05) which is statistically significant. Conclusion: Primary total hip replacement has better functional outcomes in comparison to hemiarthroplasty In fracture neck of femur in elderly patients.
