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

Clinical Description of Osteonecrosis (M87.145)

Definition and Pathophysiology

Osteonecrosis is a serious condition that can lead to joint pain, limited mobility, and eventual joint collapse if not treated appropriately. The condition arises when blood flow to a bone is disrupted, leading to the death of bone cells. In the case of M87.145, the osteonecrosis is attributed to the use of certain medications, which can interfere with blood supply or bone metabolism.

Causes

The primary cause of osteonecrosis in this context is the use of specific drugs. Common medications associated with drug-induced osteonecrosis include:

• Corticosteroids: Long-term use of corticosteroids is one of the most recognized causes of osteonecrosis. These drugs can affect bone metabolism and blood supply.
• Chemotherapy agents: Certain cancer treatments can also lead to osteonecrosis by damaging blood vessels or bone cells.
• Other medications: Some medications used for conditions like osteoporosis or rheumatoid arthritis may also contribute to the risk of developing osteonecrosis.

Symptoms

Patients with osteonecrosis of the left finger(s) may experience a range of symptoms, including:

• Pain: Initially, pain may be mild and intermittent but can progress to severe pain, especially during movement.
• Swelling: The affected area may become swollen and tender.
• Limited range of motion: As the condition progresses, patients may find it difficult to move their fingers normally.
• Joint stiffness: Stiffness in the affected finger joints can occur, particularly after periods of inactivity.

Diagnosis

Diagnosis of osteonecrosis typically involves a combination of clinical evaluation and imaging studies. Key diagnostic methods include:

• X-rays: Initial imaging may show changes in bone structure, but early stages may not be visible.
