Abstract Osteonecrosis of the femoral head is an increasingly common cause of musculoskeletal disability as well as a major diagnostic and therapeutic challenge. The natural history of this disease is important to understand because the rate of femoral head collapse and treatment options are related to multiple factors including the cause of the disease, its stage at initial presentation, and the size and location of the lesion. The results of new pharmacologic and biophysical treatments appear beneficial in delaying, and possibly preventing, the progression of precollapse lesions. New bone grafting strategies may enhance the results of core decompression. Nonoperative treatments include protected weightbearing, physical therapy and pharmacologic treatments. Operative treatment includes core decompression with or without grafting, osteotomy, hemiarthroplasty, hemiresurfacing, total resurfacing and total hip arthroplasty. Keywords: Osteonecrosis, avascular necrosis of the femoral head. |
