G57.4 Lesion of medial popliteal nerve

Name of the Condition

• Lesion of Medial Popliteal Nerve

Summary

This condition involves damage or injury to the medial popliteal nerve (also called the tibial nerve), which supplies motor and sensory functions to the lower leg and foot. Impairment can lead to functional difficulties in the affected limb.

Causes

Common causes include physical trauma, prolonged pressure on the nerve, or underlying medical conditions such as diabetes or vascular diseases that affect nerve health.

Risk Factors

Risk factors include repetitive leg motions, obesity, diabetes, peripheral artery disease, and engaging in activities or sports that risk leg injuries.

Symptoms

Patients may experience pain, tingling, numbness, or weakness in the calves, soles of the feet, and toes. Severe cases might lead to muscle paralysis in the affected area.

Diagnosis

Diagnosis typically involves a physical examination, patient history, nerve conduction studies, and electromyography (EMG) to assess the nerve's functionality and pinpoint the lesion's location.

Treatment Options

Treatments may include rest, physical therapy, anti-inflammatory medications, and in severe cases, surgical intervention to relieve nerve compression or repair nerve damage.

Prognosis and Follow-Up

Prognosis depends on the severity and cause of the lesion. Early intervention often improves outcomes, while chronic or severe cases may require long-term management. Regular follow-up with a healthcare provider is recommended to monitor recovery and adjust treatment as needed.

Complications

Potential complications include persistent weakness, chronic pain, muscle atrophy, or permanent sensory loss in the affected limb.

Lifestyle & Prevention

Maintaining a healthy weight, managing diabetes or vascular conditions, and avoiding repetitive leg motions can reduce risk. Protective measures during sports or activities may also help prevent injury.

When to Seek Professional Help

Seek medical attention if symptoms worsen, persist, or interfere with daily activities. Immediate care is advised for sudden severe pain, loss of sensation, or inability to move the foot or toes.

Tips for Medical Coders

Document the location and laterality of the lesion, as well as any contributing factors (e.g., trauma, diabetes). Ensure clinical details support the diagnosis and align with the specific nerve affected.
