Effect of combined anteversion on outcomes in total hip replacement

Osteonecrosis of the femoral head is a debilitating disease where the bone tissue dies as a result of impaired blood flow, which affects young adults and in most cases, it leads to collapse in the absence of surgical intervention. In this analytical cross-sectional study, 30 patients with osteonecrosis of the femur head were compared to determine the treatment outcomes of operative management using total hip arthroplasty (THA) and conservative treatment over 18 months. Operative group showed considerably better results with a change in Modified Harris Hip Score of 457 to 756 at 6 months compared to 467 to 687 in the conservative group (p=0.02). At 6 months, the operative group (7.2+1.3 to 2.5+0.9) had lower pain than the conservative group (7.5+1.1 to 3.8+1.1) according to Visual Analog Scale (p=0.01). The rates of radiological union were higher in the operative group (95% vs 70% at 6 months, p=0.04), showing that THA offers a far better functional outcome, pain relief and bone healing than conservative treatment of osteonecrosis of the femoral head.
