Neck and arm pain (pinched nerve in the neck)

What it is

With age, the discs and joints of the neck wear (cervical spondylosis). A disc bulge or bony spur can press on a nerve leaving the spine, causing pain down the arm. This is called cervical radiculopathy.

If the spinal cord itself is squeezed, the condition is called cervical myelopathy. It affects the hands and walking and needs prompt attention.

How we diagnose it

• Examination of strength, sensation, reflexes and walking
• An MRI scan of the neck
• Nerve conduction studies and EMG, to tell a pinched nerve in the neck from a trapped nerve at the wrist or elbow

When surgery is needed

Surgery is considered when arm pain or weakness does not settle, and is usually recommended when the spinal cord is compressed, to stop the condition worsening.

Depending on the problem, the operation is done from the front of the neck (removing the disc and fusing the level, or replacing the disc in selected patients) or from the back (widening the canal).

Recovery

The hospital stay is usually short. Arm pain often improves early. Recovery of strength and hand function after spinal cord compression is slower and depends on how long the cord was affected.

All surgery carries risks, including infection, bleeding and nerve injury. Dr Mba will explain the risks and benefits that apply to you before any decision is made.
