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

Clinical Description of M87.337

Definition of Osteonecrosis

Osteonecrosis, also known as avascular necrosis, occurs when blood flow to a bone is disrupted, leading to the death of bone cells. This can result from various factors, including trauma, prolonged use of corticosteroids, excessive alcohol consumption, or certain medical conditions such as sickle cell disease or lupus[1][2].

Specifics of M87.337

• Location: The code M87.337 specifically indicates that the osteonecrosis is located in the right carpus, which is the group of eight small bones in the wrist. This area is crucial for wrist movement and stability.
• Secondary Osteonecrosis: The term "secondary" implies that the osteonecrosis is not idiopathic (of unknown origin) but rather a consequence of another underlying condition or factor. This could include previous trauma, systemic diseases, or other medical interventions that compromise blood supply to the carpal bones[3].

Symptoms

Patients with osteonecrosis of the carpus may experience:
- Pain: Often localized to the wrist, which may worsen with activity.
