Health A to Z
Cervical spondylosis is the medical term for neck pain caused by age-related ‘wear and tear’ to bones and tissues.
However, many people with cervical spondylosis experience no noticeable symptoms.

In most cases, the symptoms of cervical spondylosis can be relieved using a combination of:
In a small number of cases, surgery may be required to remove or repair a damaged section of the cervical spine (see below).

As people get older, the effects of ageing and everyday use causes wear to the joints and tissues that make up the spine. For example, the discs of the spine can dry out and shrink, and the ligaments can stiffen.
In all the body's joints, there is a constant process of "wear and repair" happening, as the joints adapt to the stresses and strains of normal everyday life.
Cervical spondylosis occurs when the balance of "wear and repair" is lost, leading to pain and stiffness in the neck.

Cervical spondylosis is a very common condition. It's estimated that 9 out of 10 adults will have some degree of cervical spondylosis by the time they are 60 years old (but many will not have any noticeable symptoms).
The outlook for most cases of cervical spondylosis is generally good. Most cases respond well to treatment after a few weeks, though it can be common for symptoms to reoccur later.
In around 1 in 10 cases, a person can go on to develop long-term (chronic) neck pain.
Occasional headaches may also occur, which usually start at the back of the head, just above the neck, and travel over the top to the forehead.
Pain usually comes and goes, with flare-ups followed by symptom-free periods.
Around 1 in 10 people develop long-lasting (chronic) pain.
Other, more severe, symptoms usually only occur if you develop:
These problems are described in more detail below.
The most common symptom of cervical radiculopathy is a sharp pain that "travels" down one of your arms (also known as brachialgia).
You may also experience some numbness or "pins and needles" in the affected arm, and find that stretching your neck and turning your head makes the pain worse.
Cervical myelopathy occurs when severe cervical spondylosis causes narrowing of the spinal canal and compression of the spinal cord.
When the spinal cord is compressed, it interferes with the signals that travel between your brain and the rest of your body. Symptoms can include:
If you think you are experiencing symptoms of cervical myelopathy, see your GP as soon as possible.
Left untreated, cervical myelopathy can lead to permanent spinal cord damage and long-term disability.
Cervical spondylosis is caused by age-related wear that affects the spine.
The spine is made up of:
As you get older, the discs tend to dry out and become susceptible to damage. Your body will also try to compensate for the wearing of the joints by producing small lumps of extra bone to better support your neck and stiffen the spine. These lumps of extra bone are known as bone spurs or osteophytes.
Osteophytes can cause the spine to become too rigid, leading to stiffness and neck pain. The changes in bone structure can also squash nearby nerves and the spinal cord. This tends to be more common in older people.
Apart from age, there are several other risk factors that may increase the chance of developing cervical spondylitis. These include:
A slipped disc, also known as a prolapsed or herniated disc, is when one of the discs that sit between the bones of the spine (the verterbrae) is damaged and presses on the nerves that come out from the spine.
If this soft material presses against a nerve in the neck, it can cause severe pain radiating to the arm (cervical radiculopathy), and can occasionally result in compression of the spinal cord (cervical myelopathy).
Slipped discs are generally seen in younger people and are not as common as the process of osteophyte formation described above.

There is some evidence that people who spend a lot of time carrying heavy weights on their head have an increased risk of developing cervical spondylosis.
For example, a study found that rates of cervical spondylosis were much higher than average in Ghanaians, as in Ghana there is a common practice of transporting heavy loads in this manner.
Cervical spondylosis is usually suspected if there are typical symptoms of neck pain and stiffness. It will also be considered as a cause of radiating arm pain, problems with use of the hands or difficulty walking.
Various tests, described below, can be used to rule out other conditions and confirm the diagnosis.
Cervical spondylosis can limit the range of movement in your neck. You will be asked to rotate your head from side to side and tilt your head towards your shoulders.
Your GP may also test reflexes in your hands and feet, and check that you have full sensation in all your limbs. Problems with your reflexes or a lack of sensation could indicate nerve damage caused by narrowing of your spinal cord (cervical myelopathy).
You may be referred for an X-ray, which will show characteristic features of spondylosis, such as the presence of osteophytes (lumps of extra bone).
Further testing may be required if cervical myelopathy is suspected, or your symptoms are severe and fail to respond to conventional treatments.
Details of some of the tests you may have are described below.
A magnetic resonance imaging (MRI) scan is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body.
An MRI scan can be useful in detecting underlying nerve damage.
A computerised tomography (CT) scan involves taking a series of X-rays, which are then reassembled by a computer to produce a more detailed image.
CT scans can provide a much more detailed scan of your bones compared to an X-ray.
A CT scan is usually only performed if you are unable to have a MRI scan for medical reasons – for example, if you have a pacemaker.
In some cases, a nerve conduction test and electromyography may help to diagnose cervical radiculopathy or cervical myelopathy.
A nerve conduction test measures the strength and speed of the signals transmitted through your peripheral nerves – the network that runs from your brain to other areas of your body, such as your limbs.
During a nerve conduction test, small metal discs called electrodes are placed on your skin. The electrodes release small electric shocks that stimulate your nerves. The speed and strength of the nerve signal is measured.
Electromyography involves having a small needle-shaped electrode inserted through your skin and into your muscle, using a local anaesthetic.
Both types of test are usually carried out at the same time to obtain a more detailed assessment of how well your nerves and muscles are functioning.
Treatment for cervical spondylosis aims to relieve symptoms of pain and prevent permanent damage to your nerves.
Non-steroidal anti-inflammatory drugs (NSAIDs) are thought to be the most effective painkillers for symptoms of cervical spondylosis. Some commonly used NSAIDs include:
If one NSAID fails to help with pain, you should try an alternative.
However, NSAIDs may not be suitable if you have asthma, high blood pressure, liver disease, heart disease or a history of stomach ulcers. In these circumstances, paracetamol is usually more suitable. Your pharmacist or GP can advise you.
If your pain is more severe, your GP may prescribe a mild opiate painkiller called codeine. This is often taken in combination with NSAIDs or paracetamol.
A common side effect of taking codeine is constipation. To prevent constipation, drink plenty of water and eat foods high in fibre, such as wholegrain bread, brown rice, pasta, oats, beans, peas, lentils, grains, seeds, fruit and vegetables.
Codeine may be unsuitable for a number of people, especially if taken for long periods of time. Your GP can advise on whether it is safe for you to take codeine.
It is generally not recommended for people who have breathing problems (such as asthma) or head injuries, particularly those that increase pressure in the skull.
If you experience spasms, when your neck muscles suddenly tighten uncontrollably, your GP may prescribe a short course of a muscle relaxant such as diazepam.
Muscle relaxants are sedatives that can make you feel dizzy and drowsy. If you have been prescribed diazepam, make sure you do not drive. You should also not drink alcohol, as the medication can exaggerate its effects.
Muscle relaxants should not be taken continuously for longer than a week to 10 days at a time.
If pain persists for more than a month and has not responded to the above painkillers, your GP may prescribe a medicine called amitriptyline.
Amitriptyline was originally designed to treat depression, but doctors have found that a small dose is also useful in treating nerve pain. You may experience some side effects when taking amitriptyline, including:
Do not drive if amitriptyline makes you drowsy. Amitriptyline should not be taken by people with a history of heart disease.
Gabapentin (or a similar medication called pregabalin) may also be prescribed by your GP for helping radiating arm pain or pins and needles caused by nerve root irritation.
Some people may experience side effects that disappear when they stop the medication, such as a skin rash or unsteadiness. Gabapentin needs to be taken regularly for at least two weeks before any benefit is judged.
If your radiating arm pain is particularly severe and not settling, there may be an option of a "transforaminal nerve root injection", where steroid medication is injected into the neck where the nerves exit the spine. This may temporarily decrease inflammation of the nerve root and reduce pain.
Side effects include headache, temporary numbness in the area and, in rare cases, spinal cord injury (limb paralysis).
Your GP would have to refer you to a pain clinic if you wished to explore this option.
You could consider:
The long-term use of a neck brace or collar is not recommended, as it can make your symptoms worse. Do not wear a brace for more than a week, unless your GP specifically advises you to.
Surgery is usually only recommended in the treatment of cervical spondylosis if:
Surgery may also be recommended if you have persistent pain that fails to respond to other treatments.
It's important to stress that surgery often doesn't lead to a complete cure of symptoms. It may only be able to prevent symptoms from getting worse.
The type of surgery used will depend on the underlying cause of your pain or nerve damage. Surgical techniques that may be used include:
Most people can leave hospital within three to four days, but it can take up to eight weeks before you can resume normal activities. This may have an impact on your employment, depending on the type of work you do.
Many people are recommended to return to work on a part-time basis at first, although you should discuss this with your employer before surgery.
Like all surgical procedures, surgery on the cervical spine carries some risk of complications, including:
If it's decided that you could benefit from surgery, your consultant will discuss the risks and benefits with you.
