Osteonecrosis of the Hip

Abstract

Osteonecrosis of the hip is a debilitating disease that primarily affects adults in their fourth decade of life. The disease can lead to severe arthritis and can either be caused by a traumatic event or be associated with various direct or indirect risk factors. Total hip arthroplasty or hip resurfacing is indicated for patients with late-stage disease. However, alternative treatment options, including core decompression, osteotomy, and bone grafting, may improve long-term outcomes in those with less advanced disease. The key to management is early diagnosis, before collapse of the hip. The practitioner must therefore have a high degree of suspicion for the disease in patients presenting with hip pain and other factors associated with it.
