ICD-10: M62.27

The ICD-10 code M62.27 refers to "Nontraumatic ischemic infarction of muscle, ankle and foot." This condition is characterized by a lack of blood supply to the muscles in the ankle and foot, leading to tissue damage or necrosis. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this diagnosis is crucial for effective management and treatment.

Clinical Presentation

Definition and Pathophysiology

Nontraumatic ischemic infarction of muscle occurs when there is a significant reduction or cessation of blood flow to the muscle tissue, resulting in ischemia. This can be due to various factors, including vascular occlusion, embolism, or systemic conditions that impair blood flow. The ankle and foot are particularly susceptible due to their distal location in the circulatory system, where blood flow can be compromised more easily.

Common Causes

• Atherosclerosis: Narrowing of the arteries due to plaque buildup can lead to reduced blood flow.
• Embolism: A blood clot or debris that travels through the bloodstream can lodge in the arteries supplying the ankle and foot.
• Vasculitis: Inflammation of blood vessels can also contribute to ischemia.
• Diabetes Mellitus: Patients with diabetes are at higher risk for vascular complications, including ischemic events.

Signs and Symptoms

Key Symptoms

Patients with nontraumatic ischemic infarction of muscle in the ankle and foot may present with a variety of symptoms, including:

• Pain: Often described as severe and may be localized to the affected area. Pain can worsen with activity and improve with rest.
• Weakness: Affected muscles may exhibit weakness, making it difficult for patients to perform normal activities.
• Swelling: Edema may occur in the affected area due to tissue damage and inflammation.
• Color Changes: The skin may appear pale, bluish, or mottled due to inadequate blood supply.
• Temperature Changes: The affected limb may feel cooler compared to the other limb, indicating reduced blood flow.
• Numbness or Tingling: Patients may experience sensory changes in the affected area.

Physical Examination Findings

During a physical examination, healthcare providers may observe:

• Decreased Pulses: Diminished or absent pulses in the dorsalis pedis or posterior tibial arteries.
• Muscle Atrophy: Over time, affected muscles may show signs of atrophy due to lack of use and blood supply.
• Ulceration or Necrosis: In severe cases, skin ulcers or necrotic tissue may develop due to prolonged ischemia.

Patient Characteristics

Demographics

• Age: More common in older adults, particularly those over 60 years of age, due to age-related vascular changes.
• Gender: May have a slight male predominance, although both genders are affected.

Risk Factors

• Chronic Conditions: Patients with diabetes, hypertension, or hyperlipidemia are at increased risk.
• Lifestyle Factors: Smoking and sedentary lifestyle contribute to vascular health deterioration.
• History of Vascular Disease: Previous episodes of peripheral artery disease or ischemic events increase susceptibility.

Comorbidities

Patients may present with other comorbid conditions that complicate the clinical picture, such as:
- Peripheral Artery Disease (PAD): Often coexists with ischemic muscle infarction.
- Heart Disease: Patients may have underlying cardiovascular issues that affect overall circulation.
- Neuropathy: Diabetic neuropathy can mask symptoms, leading to delayed diagnosis.
