Rheumatoid Arthritis of the Spine

Rheumatoid arthritis can affect the joints and ligaments of the neck, most often right at the top, where the skull meets the spine. Most people with it have some neck pain or changes on an X-ray that never go on to cause nerve problems, and keeping your arthritis well controlled is the best protection. Surgery is only needed for the few whose neck becomes unstable or starts pressing on the spinal cord.

What Is Rheumatoid Arthritis of the Spine?

Rheumatoid arthritis (RA) is an autoimmune condition. Your immune system attacks the lining of your joints. Over time this damages cartilage, bone and the ligaments that hold joints together. Most people know RA from their hands, wrists and feet, but the neck (cervical spine) is one of the most common places it shows up. It rarely affects the mid or lower back.

It's a different problem from everyday wear and tear of the neck (cervical spondylosis). It's also different from ankylosing spondylitis, which mainly affects the lower back and pelvis. On a report you may see it called rheumatoid cervical spine, rheumatoid spondylitis or C1–C2 instability.

How Does RA Damage the Neck?

The inflamed joint lining thickens into a tissue called pannus. It releases enzymes that eat into bone and loosen ligaments. Once the ligaments holding the top two vertebrae together go slack, the spine can slip out of line. There are three main patterns, and some people have more than one.

Who Gets It?

Neck involvement usually builds up over years, and it tends to follow how active your arthritis is elsewhere. It's more likely if you:

• Have had RA for many years
• Have active disease, with high inflammation markers (ESR, CRP) in your blood tests
• Test positive for rheumatoid factor
• Have erosions in the joints of your hands or feet
• Have taken steroids for a long time

It's also more common in women, as RA itself is.

How Serious Is It?

Usually, not very. Neck pain is common in RA, and many people have changes on their X-rays. Only a minority ever develop pressure on the spinal cord or nerves.

Doctors still take it seriously for one reason. The top of the neck sits right next to the brainstem and upper spinal cord, and pressure building there unnoticed can cause lasting weakness. That's why new symptoms matter. The encouraging part is that modern RA medicines have made neck surgery far less common than it was twenty years ago.

What Are the Symptoms?

Early on, most people notice:

• Pain at the top of the neck and back of the head, often with headaches there
• Stiffness and less neck movement
• Pain that spreads to the ear or face
• A clunk, or a feeling that your head is falling forward, when you bend your neck

If the spinal cord or nerves are involved, you might notice:

• Tingling, numbness or clumsiness in the hands, such as dropping things or struggling with buttons
• An electric-shock feeling down your back or limbs when you bend your neck
• Unsteady walking or poor balance
• Weakness in the arms or legs
• Dizziness, ringing in the ears, blurred or double vision, or trouble swallowing

One catch: RA in your hands, wrists and knees can hide these signs, because weakness gets blamed on sore joints. If something feels different from your usual arthritis, mention it.

How Is It Diagnosed?

RA can affect the neck without causing any symptoms at all. So neck X-rays are recommended for everyone with RA, even if your neck feels fine.

Your doctor will check your reflexes, hand function and walking, and ask how long you've had RA and what you take for it. Tests may include:

• Neck X-rays with bending views – taken with your head bent forward and back, to see whether the top vertebrae move more than they should
• MRI scan – shows the pannus, how much space is left for the spinal cord, and any pressure on it. An X-ray alone can underestimate the problem, because the inflamed tissue doesn't show up on it
• CT scan – shows the bone in fine detail, and is used to plan surgery
• Blood tests – usually arranged by your rheumatologist to track how active your RA is

I Have RA and Need Another Operation. Is My Neck a Concern?

It can be, so tell your anaesthetist you have RA. For a general anaesthetic, the neck is usually tilted back to place a breathing tube, and an unstable neck doesn't tolerate that well. If you've had RA for a long time, your anaesthetist may want neck X-rays first. They may also place the tube using a thin camera while keeping your neck still. This applies to any operation, whether it's a knee replacement or dental surgery under general anaesthetic.

Will It Get Worse Over Time?

It can, particularly when RA isn't well controlled. The slip at C1–C2 may slowly increase, and the odontoid can creep upward over years. Keeping your RA under control is what slows this down.

Timing matters. People treated before weakness sets in recover much better than those treated after they've lost the ability to walk. So new symptoms shouldn't wait for your next routine appointment.

Because changes can happen quietly, your doctor will suggest neck X-rays at regular intervals, even when you feel well. This catches any increase in the slip early.

What Non-Surgical Treatments Are Available?

Most people with RA in the neck never need an operation.

• Regular monitoring – periodic neck X-rays with bending views, and checks of your reflexes, hands and walking. An MRI is added if the X-rays show the space for the spinal cord is getting tight
• Controlling the arthritis – disease-modifying medicines such as methotrexate, and biologic medicines, prescribed by your rheumatologist. This is the most important treatment for your neck too. Don't stop them without talking to your rheumatologist first
• Pain relief – simple painkillers and anti-inflammatories, as your doctor advises
• Physiotherapy – gentle posture and strengthening work. Avoid neck manipulation or "cracking" by anyone, as it isn't safe on an unstable neck
• Soft collar – can help with comfort during a flare. A collar can't stop the vertebrae slipping, and rigid collars often irritate fragile skin

When Is Surgery Needed?

Surgery is usually advised when:

• MRI shows the spinal cord is being squeezed, or there's a change in signal inside the cord
• You have symptoms from the cord or nerves, such as weakness, clumsy hands or unsteady walking
• The top of the neck is clearly unstable and the space for the cord is getting tight, even if you feel fine
• Pain at the top of the neck is severe and doesn't settle with other treatment

Plenty of people have instability on an X-ray with little pain and no nerve symptoms, and many of them can be safely watched. Telling the two groups apart takes careful judgement. If you've been advised surgery, or told to wait and watch, and would like another view, you can get a second opinion on your MRI.

What Does Surgery Involve?

The aim is to hold the unstable vertebrae still so they heal together into solid bone (fusion), and to take pressure off the spinal cord. The operation depends on which pattern you have:

• C1–C2 fusion – for instability between the top two vertebrae. Screws are placed in C1 and C2 and joined with rods, with bone graft, through a cut at the back of the neck
• Occipitocervical fusion – when the odontoid has risen into the skull, the fixation runs from the base of the skull down into the neck
• Lower neck fusion – screws and rods across the slipped levels lower down, sometimes combined with one of the above

The inflamed tissue behind the odontoid often shrinks on its own once the joint is held still, so an operation through the mouth or nose to remove it is rarely needed now. The breathing tube is placed with extra care, often using a camera.

What Is Recovery Like?

Most people are up and walking within a day or two and go home within a few days, depending on their general health. You may wear a collar for some weeks, and the bones take several months to fuse fully.

A few things are specific to RA:

• Neck movement – about half of your head's side-to-side turning happens at C1–C2, so a fusion there limits it. Most people adapt by turning their shoulders. A skull-to-neck fusion also limits nodding
• Healing – RA and its medicines slow wound healing and raise the risk of infection. Your surgeon and rheumatologist will plan together when to pause and restart medicines such as biologics
• Later on – the levels below a fusion can loosen years afterwards. You'll keep having neck X-rays from time to time after surgery, even if you feel well, and you should let your doctor know about any new neck or arm symptoms

Can It Be Prevented?

Not entirely, but you can lower the risk:

• Keep your RA well controlled and take your medicines as prescribed
• Keep up with your neck X-rays, even when your neck feels fine
• Stop smoking, as it makes RA more active
• Use steroids at the lowest dose, for the shortest time, your rheumatologist advises
• Mention neck pain, headaches at the back of the head, or hand tingling at your reviews
• Always tell your anaesthetist you have RA

Questions to Ask Your Doctor

• Is my neck affected by my RA, and which part?
• Is my neck stable, or is it moving more than it should?
• Is there any pressure on my spinal cord?
• How often should my neck be X-rayed?
• Do I need a neck X-ray before my planned operation?
• What symptoms should make me contact you straight away?
• If I need surgery, which levels would be fused, and how much movement would I lose?
