ICD-10: M87.834

ICD-10 code M87.834 refers to "Other osteonecrosis of right ulna," a condition characterized by the death of bone tissue due to a lack of blood supply. This condition can lead to significant morbidity and functional impairment, particularly in the affected limb. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with this diagnosis.

Clinical Presentation

Definition and Pathophysiology

Osteonecrosis, also known as avascular necrosis, occurs when blood flow to a bone is disrupted, leading to the death of bone cells. In the case of the ulna, this can result from various factors, including trauma, corticosteroid use, excessive alcohol consumption, or underlying medical conditions such as lupus or sickle cell disease. The right ulna, being one of the two long bones in the forearm, plays a crucial role in wrist and elbow function.

Signs and Symptoms

Patients with osteonecrosis of the right ulna may present with a variety of signs and symptoms, which can vary in severity:

• Pain: The most common symptom is pain in the forearm, which may be localized to the area around the ulna. The pain can be dull or sharp and may worsen with activity or weight-bearing.
• Swelling: There may be noticeable swelling around the affected area, which can indicate inflammation or fluid accumulation.
• Limited Range of Motion: Patients may experience stiffness and reduced mobility in the wrist and elbow joints, making it difficult to perform daily activities.
• Tenderness: The area over the ulna may be tender to touch, indicating inflammation or irritation of the surrounding tissues.
• Deformity: In advanced cases, there may be visible deformities in the forearm due to bone collapse or changes in joint alignment.

Progression of Symptoms

The symptoms of osteonecrosis can progress over time. Initially, patients may experience intermittent pain, which can become constant as the condition worsens. If left untreated, the necrotic bone may collapse, leading to more severe pain and functional impairment.
