ICD-10: M62.26

ICD-10 code M62.26 refers to nontraumatic ischemic infarction of muscle in the lower leg. This condition is characterized by the death of muscle tissue due to a lack of blood supply, which can occur without any external injury or trauma. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description

Definition

Nontraumatic ischemic infarction of muscle occurs when there is a significant reduction or complete cessation of blood flow to the muscle tissue, leading to ischemia (insufficient blood supply) and subsequent necrosis (tissue death). In the case of the lower leg, this can affect muscles such as the gastrocnemius, soleus, and tibialis anterior.

Etiology

The causes of nontraumatic ischemic infarction can vary and may include:
- Vascular occlusion: This can be due to thrombosis (blood clots) or embolism (a traveling clot) that obstructs blood flow.
- Atherosclerosis: The buildup of fatty deposits in the arteries can narrow them, reducing blood flow.
- Vasculitis: Inflammation of blood vessels can lead to narrowing or blockage.
- Hypotension: Severe drops in blood pressure can compromise blood flow to the extremities.
- Systemic conditions: Conditions such as diabetes or peripheral artery disease can predispose individuals to ischemic events.

Symptoms

Patients with nontraumatic ischemic infarction of the lower leg may present with:
- Pain: Often described as severe and may be localized to the affected muscle.
- Weakness: Difficulty in moving the affected leg or foot.
- Swelling: The area may appear swollen due to inflammation or fluid accumulation.
- Color changes: The skin may appear pale, bluish, or mottled due to inadequate blood supply.
- Loss of function: In severe cases, there may be a complete loss of muscle function in the affected area.

Diagnosis

Diagnosis typically involves:
- Clinical evaluation: A thorough history and physical examination to assess symptoms and risk factors.
- Imaging studies: Doppler ultrasound, MRI, or CT angiography may be used to visualize blood flow and identify blockages.
- Laboratory tests: Blood tests may be conducted to check for markers of muscle damage (e.g., creatine kinase levels).

Treatment

Management of nontraumatic ischemic infarction of muscle may include:
- Medical therapy: Anticoagulants or thrombolytics may be prescribed to dissolve clots and restore blood flow.
- Surgical intervention: In some cases, procedures such as angioplasty or bypass surgery may be necessary to restore circulation.
- Rehabilitation: Physical therapy may be recommended to regain strength and function in the affected muscle.
