S14.145 Brown-Sequard syndrome at C5 level of cervical spinal cord

Name of the Condition

• Brown-Sequard syndrome at C5 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 C5 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 C5 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 C5 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

• Ipsilateral (same side) motor weakness or paralysis below the injury level.
• Loss of proprioception (position sense) on the same side as the injury.
• Contralateral (opposite side) loss of pain and temperature sensation.
• Possible autonomic dysfunction, such as changes in blood pressure or bladder control.

Diagnosis

Diagnosis involves a thorough neurological examination to assess motor and sensory deficits. 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 function. Clinical correlation with the patient’s history and symptoms is essential to confirm the diagnosis.

Treatment Options

Treatment focuses on stabilizing the spine, managing symptoms, and preventing complications. This may include immobilization, surgical intervention to relieve compression, and rehabilitation to improve function. Medications may be used to control pain or address autonomic issues. Long-term care often involves physical and occupational therapy.

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. Follow-up care includes regular neurological assessments, imaging to monitor spinal cord status, and adjustments to treatment plans as needed. Rehabilitation is a key component of long-term management.

Complications

• Permanent motor or sensory deficits.
• Autonomic dysfunction, such as bladder or bowel issues.
• Increased risk of infections (e.g., urinary tract infections).
• Chronic pain or spasticity.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., helmets, neck braces).
• Maintain good posture and avoid repetitive neck strain.
• Engage in regular exercise to strengthen neck and back muscles.
• Seek prompt medical attention for neck injuries to prevent further damage.

When to Seek Professional Help

• Sudden onset of weakness, numbness, or loss of sensation in the arms or legs.
• Difficulty with balance or coordination.
• Changes in bladder or bowel control.
• Severe neck pain following trauma.

Tips for Medical Coders

Document the specific level of the cervical spinal cord (C5) and confirm the presence of Brown-Sequard syndrome characteristics (ipsilateral motor/proprioception loss, contralateral pain/temperature loss). Ensure clinical documentation supports the diagnosis and level of injury for accurate coding.
