Cervical and thoracic myelopathy explained

The compression level influences which functions change. Cervical cord disease can affect the hands, arms, trunk, and legs, while thoracic cord disease generally affects the trunk and legs below the compressed level without directly causing a nerve-root pattern in the hands.

Myelopathy means that spinal cord function is impaired. In the neck, degenerative discs, bone spurs, enlarged joints, thickened ligaments, or other space-occupying problems can narrow the canal. In the thoracic spine, causes can also include degenerative narrowing, disc material, ligament changes, or a mass. More than one level can be involved, so symptoms alone may not locate every site.

Cervical myelopathy may cause hand clumsiness, altered arm sensation, brisk reflexes, leg stiffness, imbalance, or walking difficulty. Thoracic myelopathy more often produces leg heaviness or weakness, an unsteady or stiff gait, and a band-like sensory change around the trunk. Either location can disturb bladder or bowel control when cord dysfunction is substantial.

The assessment combines the history with tests of arm and leg power, sensation, reflexes, hand coordination, balance, and gait. The upper boundary of altered sensation and the pattern of reflex changes can help localise the affected cord region. Magnetic resonance imaging is used to view suspected cervical or thoracic levels and identify what is pressing on the cord.

Care is tailored to the cause, progression, neurological loss, and overall health. Monitoring and carefully selected rehabilitation may be appropriate in some stable presentations. Progressive compression can require a spinal surgical opinion; decompression may involve laminectomy, and cervical procedures may include fusion when stability or alignment needs support. Rehabilitation after treatment focuses on safe mobility, strength, balance, and practical function.

Get urgent medical help for sudden or rapidly worsening limb weakness, an abrupt loss of walking ability, repeated unexplained falls, new saddle numbness, or new loss of bladder or bowel control. A major change after trauma also requires prompt evaluation.

Progressive hand clumsiness, a stiff or dragging leg, a tightening band of altered feeling around the chest or abdomen, and steadily declining balance deserve timely assessment even without severe spinal pain.

Ask where the examination places the cord problem, whether imaging of both neck and thoracic regions is needed, and what is causing the compression. It is also useful to clarify which neurological changes are reversible, what treatment aims to preserve, how mobility risks should be managed now, and how follow-up will detect progression.
