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.
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 کامل[Diagnosis of avascular necrosis of the femoral head].
Mechanical factors have now been excluded as the main cause of non-union in fractures of the femoral neck : the development of efficient methods of internal fixation has removed this source of non-union and the chief remaining cause is disturbance of the circulation of blood to the capital fragment. The incidence of avascular necrosis of the femoral head appears to depend upon normal variations...
متن کاملCortisone-induced avascular necrosis of the femoral head.
Of ninety-five patients with corticosteroid-induced avascular necrosis of bone, ninety-one had involvement of the femoral head. The risk of developing this lesion appeared to be correlated with the total steroid dose. Forty-nine patients demonstrated a subchondral osteolytic defect which healed without proceeding to collapse. Four femoral heads in four patients developed sequestration, resembli...
