M87: Osteonecrosis

M87.2: Osteonecrosis due to previous trauma

Osteonecrosis due to previous trauma (coded as M87.2 in ICD-10) is a specific medical condition where a section of bone dies because of a lack of blood supply. This can occur as a result of a previous injury or trauma to the area. When such an injury occurs, it can disrupt the blood flow to the bone, leading to the death of bone tissue, a condition known as osteonecrosis. The condition often leads to pain and limited movement in the affected area. In many instances, the symptoms of osteonecrosis do not start until the disease is quite advanced, and in some cases, it may even take years to show any symptoms. The disease can progress gradually over time, and the affected bone and the surrounding joint may eventually collapse if left untreated. Areas most commonly affected include the hips, knees, shoulders, and ankles.
