Front X-ray of right knee of an adolescent (epiphyseal plates are open): arrows point to avascular necrosis and developing osteochondritis dissecans in the outer medial condyle of femur. In the early stages, bone scintigraphy and MRI are the preferred diagnostic tools. [18] [19] X-ray images of avascular necrosis in the early stages usually ...
A radiograph of a left hip joint, which reveals a thin, curvilinear lucent line parallel to the cortical margin of the femoral head, in a patient with avascular necrosis. In radiology, the crescent sign is a finding on conventional radiographs that is associated with avascular necrosis.
Dieterich's disease, also known as avascular necrosis of the metacarpal head, [1] is an extremely rare condition characterized by temporary or permanent loss of blood supply to the metacarpal head of the metacarpal bone, resulting in loss of bone tissue.
Specifically, Kienböck's disease is another name for avascular necrosis [2] (death and fracture of bone tissue due to interruption of blood supply) with fragmentation and collapse of the lunate. This has classically been attributed to arterial disruption, but may also occur after events that produce venous congestion with elevated interosseous ...
5 Additional images. ... Damage to the artery following a femoral neck fracture may lead to avascular necrosis of the femoral neck/head. [2] Structure
A potential complication of a vertebral compression fracture is avascular necrosis of the vertebral body, which is called Kümmel's disease, and may appear with the intravertebral vacuum cleft sign (at white arrow in image). [4]
Freiberg disease, also known as a Freiberg infraction, is a form of avascular necrosis in the metatarsal bone of the foot. It generally develops in the second metatarsal, but can occur in any metatarsal. Physical stress causes multiple tiny fractures where the middle of the metatarsal meets the growth plate.
Chandler's disease, also known as idiopathic avascular osteonecrosis of the femoral head (ANFH or ONFH), is a rare condition in which the bone cells in the head of the femur (FH) die due to lack of blood.
