Avascular Necrosis of the Femoral Head: Are Any Genes Involved?
Avascular necrosis of the femoral head (ANFH) is a pathologic process that results from interruption of blood supply to the femur bone resulting in the death of bone cells and collapse of the femoral head. Nontraumatic ANFH continuesto be a significant challenge to orthopedic surgeons. While the exact mechanisms remain elusive, many new insights have emerged from research in the last decade tha...
متن کاملAvascular necrosis of the femoral head. Natural history and magnetic resonance imaging.
We studied the prognostic value of MRI in 32 radiographically normal, asymptomatic hips in 25 patients at risk of osteonecrosis from glucocorticoids or alcoholism. The early findings were band-like hypointense zones on spin-echo images. No operations were performed. Life-table survival curves showed that femoral heads in which the hypointense zone traversed the middle portion of the head were m...
متن کاملAvascular necrosis of the femoral head.
The patient was a 51-year-old man who was evaluated by a physical therapist for a chief complaint of right hip pain. The patient was treated with a single bout of nonthrust hip joint mobilizations, but due to the patient's atypical response and long-term use of oral corticosteroid medications, he was referred to his primary care physician. Radiographs and subsequent magnetic resonance imaging r...
متن کاملAvascular Necrosis of the Femoral Head
Since the recent publication of studies of the vascular pattern of the proximal femoral epiphysis in man by Tucker (1949), Trueta and Harrison (1953), Judet, Judet, Lagrange and Dunoyer (1955), and Trueta (1957) there has been a renewed interest in the mechanism of capital necrosis after fractures of the femoral neck. The literature on the subject is so extensive that no effort will be made her...
متن کاملCorrelation of cumulative corticosteroid treatment with magnetic resonance imaging assessment of avascular femoral head necrosis in patients with multiple sclerosis
Increased risk of osteoporosis, fractures, and avascular necrosis (AVN) has been suggested in multiple sclerosis (MS). Patients with MS are often exposed to corticosteroid treatment (CST) during the disease course and conflicting reports exist regarding complications of CST. Our study aims to investigate the association between cumulative doses of CST and radiographic evaluation of AVN of the f...
