Cervical Spinal Stenosis (Narrowing of the Spine in the Neck)

Cervical spinal stenosis means the space for your spinal cord and nerves in the neck has become narrower, usually with age. Many people have it on a scan and never feel a thing. When it does cause symptoms, most people are managed without surgery.

What is cervical spinal stenosis?

Stenosis means narrowing. In the neck, it can be the central canal that carries the spinal cord, or the small side openings where the nerves leave. When the space gets tight, the cord or a nerve can be pressed. It's usually slow and age-related, though a fall or accident can bring on symptoms suddenly in someone whose canal was already narrow.

What causes it, and who gets it?

It's most common after 50. The usual causes are:

• Bone spurs: Arthritic growths that narrow the space
• Disc degeneration: Discs lose height and bulge into the canal
• Thickened ligaments: Ligaments stiffen and thicken with age
• A naturally narrow canal: Some people are born with a smaller canal, so even mild wear causes symptoms sooner

How serious is it?

Often not very. Narrowing on an MRI doesn't always mean symptoms, and many people never need treatment. What matters is whether the spinal cord or a nerve is actually being pressed, and whether that is causing symptoms. That's what we look for.

What are the symptoms?

Cervical stenosis doesn't always cause any. When it does:

• Neck pain, sometimes spreading to the shoulders
• Numbness or tingling in the hands
• Weakness or clumsiness in the hands
• Unsteady walking or poor balance
• Bladder or bowel changes, only in severe cases

If the cord itself is pressed, it becomes Cervical Myelopathy. If the side openings are narrowed and a nerve is pinched, it causes Cervical Radiculopathy. New or quickly worsening hand weakness, trouble walking, or bladder or bowel changes need prompt assessment.

How is it diagnosed?

We start with your history and an examination. An MRI is the most useful test, because it shows how narrow the canal is and whether the cord or nerves are affected. X-rays show alignment and bone spurs, and a CT scan adds detail about the bone.

Will it get worse?

Not necessarily. Many people with mild narrowing never develop significant symptoms, and how fast it changes varies a lot from person to person. If your canal is very narrow, we keep a closer eye on you.

What non-surgical treatments are available?

• Medicines: Anti-inflammatories for pain, and sometimes nerve pain medicines. A short course of oral steroids helps some people with arm symptoms
• Physiotherapy: Keeps the neck moving and builds strength. See Neck Exercises for Pain Relief & Prevention
• Activity changes: If stenosis is significant, avoid contact sports and other high-risk activities
• A soft collar: In selected cases, to limit sudden neck movements
• Cervical epidural steroid injection: For selected people with arm pain from an irritated nerve
• Traction: We use it very rarely

When is surgery needed?

Surgery is considered when the spinal cord is being compressed and causing symptoms, when nerve symptoms stay severe despite non-surgical care, or when the neck is unstable. It's a decision made together, based on your symptoms, examination and scans.

If you're unsure about the advice you've been given, you're welcome to send your MRI for a second opinion.

What does surgery involve?

The aim is to make more room for the cord and nerves. The approach depends on how many levels are narrowed and how your neck is aligned.

• Anterior cervical discectomy and fusion (ACDF): Removes the disc and bone spurs from the front of the neck and joins the level
• Cervical laminectomy, with or without fusion: Removes the back part of the vertebra to open the canal, from the back
• Laminoplasty: Widens the canal while keeping movement, in selected patients

The options are described in more detail on the Cervical Myelopathy page.

What is recovery like?

After a single-level ACDF, most people walk on the day of surgery and go home the next day. Longer fusions, or surgery from the back, usually mean 2 to 3 days in hospital, and most people are walking within a day. Recovery continues over the following weeks and months, with physiotherapy and a gradual return to activity.

Can it be prevented?

The age-related changes can't be stopped. Staying active, keeping the neck and shoulder muscles strong, and not smoking all help. If you know you have a narrow canal, avoid activities with a risk of a heavy neck injury.

Questions to ask your doctor

• How narrow is my canal, and at which levels?
• Is my spinal cord or a nerve being pressed?
• Do I need treatment now, or can this be monitored?
• What symptoms mean I should come back sooner?
• If I need surgery, which operation, and why that one?

Treatments we offer for this

Medicines and physiotherapy guidance, cervical epidural steroid injections, anterior cervical discectomy and fusion (ACDF), cervical laminectomy with or without fusion, and laminoplasty.
