S14.144 Brown-Sequard syndrome at C4 level of cervical spinal cord

Name of the Condition

• Brown-Sequard syndrome at C4 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 C4 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 C4 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 C4 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 below the injury, and contralateral loss of pain and temperature sensation. Autonomic dysfunction, such as bladder or bowel issues, may also occur.

Diagnosis

Diagnosis involves a thorough neurological examination to assess motor, sensory, and autonomic function. Imaging studies, such as MRI or CT scans, are used to identify the location and extent of spinal cord damage. Electrophysiological tests may be performed to evaluate nerve conduction.

Treatment Options

Treatment focuses on stabilizing the spine, managing symptoms, and preventing complications. This may include surgical intervention to relieve compression, physical therapy to improve mobility, and medications to address pain or spasticity. Rehabilitation is often necessary to maximize functional recovery.

Prognosis and Follow-Up

Prognosis depends on the severity and cause of the injury. Some patients may experience partial recovery, while others may have permanent deficits. Regular follow-up with a neurologist or spinal cord injury specialist is important to monitor progress and adjust treatment as needed.

Complications

Complications can include chronic pain, spasticity, bladder or bowel dysfunction, and increased risk of infections (e.g., urinary tract infections). Respiratory issues may occur if the injury affects respiratory muscles.

Lifestyle & Prevention

Preventive measures include using proper safety equipment during high-risk activities, maintaining good posture, and addressing underlying conditions that weaken the spine. Lifestyle modifications, such as smoking cessation, may support overall spinal health.

When to Seek Professional Help

Seek immediate medical attention if you experience sudden neck pain, weakness, numbness, or loss of sensation, especially after trauma. Early intervention can improve outcomes.

Tips for Medical Coders

Document the specific cervical level (C4) and confirm the hemisection pattern of neurological deficits. Ensure clinical documentation supports the diagnosis and distinguishes it from other spinal cord injuries. Code S14.144 is specific to the C4 level; verify the injury’s location and characteristics match the code’s definition.
