Necrosis occurring without infection, e.g., as a result of trauma or drug use.
Aseptic necrosis refers to the death of bone tissue in the absence of infection. The primary cause of this condition is typically a disruption in the blood supply to the bone, often resulting from a fracture. In certain instances, aseptic necrosis is associated with the administration of corticosteroid medications as part of treatment.
Aseptic necrosis frequently leads to chronic pain and can induce stiffness in neighboring joints. Timely treatment of fractures is crucial in minimizing the likelihood of this condition from developing.
The femoral head (thigh bone) and the scaphoid (a wrist bone) are particularly susceptible to aseptic necrosis. Diagnosis of this condition can often be made through X-ray imaging, as the affected area of the bone appears denser compared to the surrounding bone.
