Background: Hip joint preserving procedures delay the progression of femoral head osteonecrosis. Non-vascularised autologous bone grafts have been used to fill necrotic area and prevent collapse head. Harvesting use neck graft, minimizing donor site complications favoring regeneration after core decompression. Methods: 17 patients in early stage osteonecrosis were operated, 12 males 5 females w...

BACKGROUND Osteonecrosis of the femoral head is a common complication of high-dose glucocorticoid treatment. Intravascular thrombosis is thought to be associated with the ischemic state of the femoral head. Plasminogen activator inhibitor-1 (PAI-1) is an adipokine, which are physiologically active substances secreted from visceral and subcutaneous adipocytes. PAI-1 suppresses fibrinolysis by bi...

PURPOSE Slipped capital femoral epiphysis (SCFE) is one of the most common adolescent hip conditions. Unstable SCFE is characterized by sudden and severe hip pain with the inability to weight bear, even with crutches. Osteonecrosis of the femoral head is increased in patients with unstable SCFE. The aim of our study was to systematically review the literature that compares hip decompression to ...

BACKGROUND Characteristically, osteonecrosis affects younger patients who typically refer to the orthopedic surgeon for the first time in the third to fifth decades of life, in the late stages of the disease. Femoral metal-on-metal hip resurfacing is as an alternative to conventional total hip arthroplasty in treating osteoarthritis of the hip. Since there are already many reports regarding the...

Hospital Physician February 2008 13 O steonecrosis of the femoral head (ONFH) is a potentially debilitating condition of unclear etiology that affects up to 20,000 persons in the United States each year.1 ONFH in adults can be devastating as it typically occurs in a relatively young population (age, 35–40 yr). The disease is usually progressive,2 and without treatment, ONFH frequently results i...

Avascular osteonecrosis of the femoral head (AONFH) usually goes through the four stages described by Arlet and Ficat: normal radiographs, heterogeneity and sclerosis of the femoral head, subchondral fracture with an individualized sequestrum, and secondary osteoarthritis. Arlet and Ficat individualized a specific pattern of AONFH which they called ischemic hip disease, in which cartilage damag...
