M87.273

Osteonecrosis, also known as avascular necrosis, is a condition characterized by the death of bone tissue due to a lack of blood supply. In the case of M87.273, the osteonecrosis is specifically attributed to previous trauma affecting the ankle region. This condition can arise after fractures, dislocations, or other significant injuries that compromise the vascular supply to the bone. The ankle joint, being a weight-bearing joint, is particularly susceptible to the effects of osteonecrosis, leading to pain, limited mobility, and potential joint degeneration. Clinically, patients may present with symptoms such as localized pain, swelling, and difficulty bearing weight on the affected ankle. Diagnosis typically involves imaging studies such as X-rays or MRI, which can reveal changes in bone density and structure indicative of necrosis. Treatment options may include conservative management with pain relief and physical therapy, or surgical interventions such as core decompression or joint replacement in advanced cases. Understanding the underlying cause of osteonecrosis is crucial for effective management and prevention of further complications.
