ICD-10: M87.376

The ICD-10 code M87.376 refers to "Other secondary osteonecrosis, unspecified foot." This condition is characterized by the death of bone tissue due to a lack of blood supply, which can lead to various clinical presentations, signs, symptoms, and patient characteristics. Below is a detailed overview of these aspects.

Clinical Presentation

Definition and Overview

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 M87.376, the osteonecrosis is secondary, meaning it results from other underlying conditions or factors rather than occurring spontaneously. The foot is the affected area, but the specific site within the foot may be unspecified.

Common Causes

Secondary osteonecrosis can arise from various factors, including:
- Trauma: Fractures or dislocations that compromise blood supply.
- Chronic corticosteroid use: Long-term use of corticosteroids can lead to decreased blood flow to bones.
- Alcohol abuse: Excessive alcohol consumption can affect blood supply and bone health.
- Medical conditions: Conditions such as sickle cell disease, lupus, or other vascular disorders can contribute to osteonecrosis[1][4].

Signs and Symptoms

General Symptoms

Patients with M87.376 may experience a range of symptoms, which can vary in severity:
- Pain: Often the most prominent symptom, pain may be localized to the affected area of the foot and can worsen with weight-bearing activities.
- Swelling: Inflammation around the affected bone may lead to noticeable swelling.
- Limited range of motion: Patients may find it difficult to move the foot or bear weight due to pain and discomfort.
