Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Osteonecrosis (ICD-10 Code M87.131)

Definition

Osteonecrosis occurs when blood flow to a bone is disrupted, leading to the death of bone cells. This condition can result from various factors, including trauma, excessive alcohol consumption, certain medical conditions, and the use of specific medications. The right radius, one of the two bones in the forearm, can be affected, leading to pain, limited mobility, and potential joint dysfunction.

Etiology

In the case of M87.131, the osteonecrosis is specifically due to drug use. Certain medications, particularly corticosteroids and bisphosphonates, have been linked to the development of osteonecrosis. Corticosteroids can interfere with blood supply to the bone, while bisphosphonates, used to treat osteoporosis, may lead to similar complications, especially in the jaw but also in other bones.

Symptoms

Patients with osteonecrosis of the right radius may experience:
- Pain: Often the first symptom, which may be localized to the wrist or forearm and can worsen with activity.
- Swelling: Inflammation around the affected area may occur.
