ICD-10: M87.14

Osteonecrosis, also known as avascular necrosis, is a condition characterized by the death of bone tissue due to a lack of blood supply. The ICD-10 code M87.14 specifically refers to osteonecrosis caused by drugs, affecting the hand and fingers. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of M87.14

Definition and Pathophysiology

Osteonecrosis due to drugs (M87.14) occurs when certain medications disrupt the blood supply to the bone, leading to bone cell death. This condition can result from various pharmacological agents, including corticosteroids, bisphosphonates, and certain chemotherapy drugs. The exact mechanism often involves the impairment of blood flow, which can be exacerbated by factors such as dosage, duration of treatment, and individual patient susceptibility[1][2].

Symptoms

Patients with osteonecrosis in the hand and fingers may experience a range of symptoms, including:
- Pain: Often the first symptom, which may be localized to the affected area and can worsen with activity.
- Swelling: Inflammation around the joints or affected bones may occur.
- Limited Range of Motion: Patients may find it difficult to move their fingers or hand due to pain and stiffness.
- Joint Instability: In advanced cases, the structural integrity of the joint may be compromised, leading to further complications[3].

Diagnosis

Diagnosis of M87.14 typically involves a combination of clinical evaluation and imaging studies. Key diagnostic steps include:
- Medical History: A thorough review of the patient's medication history, including any drugs known to cause osteonecrosis.
- Physical Examination: Assessment of pain, swelling, and range of motion in the hand and fingers.
- Imaging: X-rays, MRI, or CT scans are used to visualize bone changes and confirm the diagnosis. MRI is particularly useful in detecting early changes in bone marrow associated with osteonecrosis[4].

Treatment

Management of osteonecrosis due to drugs involves several strategies aimed at alleviating symptoms and preventing further bone damage:
- Medication Adjustment: If possible, discontinuing or switching the offending drug can halt the progression of the condition.
- Pain Management: Nonsteroidal anti-inflammatory drugs (NSAIDs) or other analgesics may be prescribed to manage pain.
- Physical Therapy: Rehabilitation exercises can help maintain joint function and improve mobility.
- Surgical Options: In severe cases, procedures such as core decompression, bone grafting, or joint replacement may be necessary to restore function and relieve pain[5][6].
