EVALUATION OF FUNCTIONAL OUTCOME BASED ON ACETABULAR COMPONENT PLACEMENT IN TOTAL HIP REPLACEMENT

Abstract

BACKGROUND; Total hip arthroplasty (THA) is one of contemporary medicine's true successes (1,2). People with crippling hip diseases could only look forward to living out their years in excruciating pain for generations. For most patients who were unfortunate enough to be aficted, the unrelenting advancement of hip illness resulted in a downward spiral of limited function. Although early attempts at inter-positional arthroplasty and resurfacing operations frequently failed, the development of contemporary THA has provided surgeons and patients with a safe and effective treatment for hip arthritis. Based on a pelvic radiograph and a CT scan, the purpose of this study is to evaluate the acetabular component version and inclination, as well as the functional outcome of total hip replacement.. METHODS: Study design: Hospital Based Retrospective study. Study period: September 2019 to August 2021. Sample size: 30 RESULTS There were 16 males and 14 females among the 30 patients. In 18 cases, the right side was damaged, while in 12 patients, the left side was affected. Avascular necrosis is the most common reason for total hip replacement in 14 patients, followed by rheumatoid arthritis in three, nonunion neck of femur in three, ignored fracture of neck of femur in two, secondary osteoarthritis in six, and ankylosing spondylitis in two. In our research, the average acetabular cup variant performed well. In axial CT, we employed a modied Murray's technique to measure acetabular version. This was the most widely used strategy in numerous investigations. This approach has a very high accuracy rating of around 95%. In all of the cases, the acetabular cup was anteverted. 90 percent of patients in our study had an excellent functional outcome, 6.3 percent had a good functional outcome, and 3.7 percent had a fair functional outcome. 86.66 percent of acetabular cup placements in our investigation were within acceptable limits. Excessive anteversion was found in just 13.33 percent of acetabular cups. CONCLUSION In our study, 90% of the cases had an excellent Harris hip score, whereas 10% had a good or fair Harris hip score. Excessive anteversion was not linked to joint dislocation, however it did result in limited internal rotation
