title: Avascular necrosis of common bones seen in the ED.
abstract: Missed diagnosis of avascular necrosis (AVN) may result in substantial morbidity. Early diagnosis is crucial for appropriate intervention and, ultimately, improved outcome. Emerging physicians need to recognize AVN to avoid unsatisfactory clinical results for their patients. Avascular necrosis (AVN) of the bone can occur when the blood supply to the bone is disrupted and is usually found in areas with terminal circulation. Commonly involved bones include the femoral head, talus, and scaphoid.
