S14.146 Brown-Sequard syndrome at C6 level of cervical spinal cord

Name of the Condition

• Brown-Sequard syndrome at C6 level of cervical spinal cord

Summary

This condition is a specific type of spinal cord injury characterized by a hemisection (partial damage to one side) of the cervical spinal cord at the C6 level. It results in a distinct pattern of neurological deficits, including ipsilateral (same side) motor weakness or paralysis and loss of proprioception (position sense) below the injury level, combined with contralateral (opposite side) loss of pain and temperature sensation. The C6 level is part of the cervical spinal cord, which transmits signals between the brain and the upper body, so injuries here can affect motor, sensory, or autonomic functions.

Causes

Brown-Sequard syndrome at the C6 level is typically caused by traumatic events, such as penetrating injuries (e.g., stab wounds or gunshot wounds) that damage one side of the spinal cord. Other traumatic causes include fractures, dislocations, or severe compression of the cervical spine. Non-traumatic causes, such as tumors, infections, or inflammatory conditions (e.g., multiple sclerosis), may also lead to this syndrome by affecting one side of the spinal cord.

Risk Factors

• Participation in high-impact sports or activities with a risk of neck injury.
• Occupations involving heavy lifting or repetitive neck strain.
• Conditions that weaken bone or tissue.

Symptoms

Symptoms include ipsilateral motor weakness or paralysis, loss of proprioception, and contralateral loss of pain and temperature sensation below the injury level. Additional signs may involve autonomic dysfunction, such as changes in blood pressure or bladder control, depending on the severity of the injury.

Diagnosis

Diagnosis involves a thorough clinical evaluation, including a detailed neurological examination to assess motor, sensory, and autonomic function. Imaging studies, such as MRI or CT scans, are typically used to identify the location and extent of spinal cord damage. Electrophysiological tests may also be performed to confirm the pattern of neurological deficits.

Treatment Options

Treatment focuses on stabilizing the injury, relieving pressure on the spinal cord, and managing symptoms. This may include surgical intervention to repair or decompress the spinal cord, followed by rehabilitation to improve motor and sensory function. Medications may be used to control pain or address autonomic issues.

Prognosis and Follow-Up

Prognosis varies based on the severity and cause of the injury. Early intervention and rehabilitation can improve outcomes, but some deficits may be permanent. Follow-up care often involves regular neurological assessments, imaging studies, and ongoing rehabilitation to monitor progress and address complications.

Complications

Potential complications include persistent motor or sensory deficits, chronic pain, autonomic dysfunction, and increased risk of infections or pressure sores due to reduced mobility. Long-term care may be required to manage these issues.

Lifestyle & Prevention

Preventive measures include using proper safety equipment during high-risk activities, maintaining good posture, and avoiding behaviors that strain the neck. For individuals with pre-existing conditions, managing underlying health issues can reduce the risk of injury.

When to Seek Professional Help

Seek immediate medical attention if symptoms of spinal cord injury occur, such as sudden weakness, numbness, or loss of sensation in the limbs, especially after trauma. Early evaluation is critical to minimize damage and improve outcomes.

Tips for Medical Coders

When coding for Brown-Sequard syndrome at the C6 level, ensure the documentation specifies the cervical spinal cord level and the hemisection pattern. Verify that the code aligns with the clinical findings and that any associated injuries or complications are appropriately documented. Accurate coding requires clear documentation of the injury’s location and neurological manifestations.
