ICD-10: M87.377

The ICD-10 code M87.377 refers to "Other secondary osteonecrosis, right toe(s)." Osteonecrosis, also known as avascular necrosis, occurs when there is a loss of blood supply to a bone, leading to bone death. This condition can affect various bones, including the toes, and is often associated with specific clinical presentations, signs, symptoms, and patient characteristics.

Clinical Presentation

Definition and Overview

Osteonecrosis is characterized by the death of bone tissue due to a lack of blood supply. Secondary osteonecrosis, as indicated by the code M87.377, typically arises from underlying conditions or factors such as trauma, corticosteroid use, alcohol abuse, or certain medical conditions like sickle cell disease or systemic lupus erythematosus. In the case of the right toe(s), the condition may manifest as localized symptoms affecting the toe bones.

Common Causes

• Trauma: Fractures or dislocations that disrupt blood flow.
• Corticosteroid Use: Long-term use can lead to fat deposits in blood vessels, reducing blood supply.
• Alcohol Abuse: Excessive alcohol consumption can affect blood flow and bone health.
• Medical Conditions: Diseases such as diabetes, rheumatoid arthritis, or hyperlipidemia can contribute to the development of osteonecrosis.

Signs and Symptoms

Localized Symptoms

• Pain: Patients often experience pain in the affected toe(s), which may worsen with activity or weight-bearing.
• Swelling: Inflammation around the toe joint may occur, leading to visible swelling.
• Tenderness: The affected area may be sensitive to touch.
• Limited Range of Motion: Patients may find it difficult to move the toe(s) due to pain and stiffness.

Systemic Symptoms

While localized symptoms are predominant, some patients may also experience systemic signs depending on the underlying cause of osteonecrosis:
- Fatigue: General tiredness may occur, especially if the condition is related to systemic diseases.
- Fever: In cases where infection is a concern, fever may be present.

Patient Characteristics

Demographics

• Age: Osteonecrosis can occur at any age but is more common in individuals aged 30 to 60 years.
• Gender: Males are generally at a higher risk than females, particularly in cases related to alcohol use or trauma.

Risk Factors
