Quick answer. Spondylosis is age-related wear-and-tear of the spine, most often in the neck (cervical) or lower back (lumbar), and is a very common cause of stiffness and aching as we get older. Most cases are managed without surgery, but new arm or leg weakness, numbness, or bladder or bowel problems need urgent assessment.
Spondylosis is the medical term for the gradual wear-and-tear changes that affect the spine with age – essentially a form of arthritis of the spinal joints and discs. It most commonly involves the neck (cervical spondylosis) or the lower back (lumbar spondylosis) and is extremely common, affecting a large proportion of older adults in Singapore to some degree, often without causing major problems.
For many people, spondylosis means occasional stiffness and aching that comes and goes. In some cases, the wear-related changes narrow the spaces where nerves travel, causing pain, numbness or weakness that radiates into an arm or leg. This guide explains what spondylosis is and how it differs from a slipped disc, how it is diagnosed, the range of treatments from conservative care to surgery, and the warning signs of nerve or spinal cord compression that need prompt attention.
At a glance
| Region | Where you feel it | Typical symptoms |
|---|---|---|
| Cervical (neck) | Neck, shoulders, into the arms | Neck stiffness, headaches, arm pain or tingling |
| Lumbar (lower back) | Lower back, buttocks, into the legs | Back stiffness, ache, leg pain on standing or walking |
| Either region | Along the affected nerve path | Numbness, pins-and-needles, weakness |
| Mild / common | Localised to the spine | Stiffness, worse in the morning or after rest |
| With nerve pressure | Radiating beyond the spine | Shooting pain, weakness – needs review |
What is spondylosis?
Spondylosis describes the natural degeneration of the spine that comes with age. Over time the discs that cushion the vertebrae lose water and height, the spinal joints develop arthritis, and small bony spurs (osteophytes) can form. These changes are a normal part of ageing and are present in most people by later life, often without symptoms.
It differs from a slipped (herniated) disc, where disc material bulges out and presses on a nerve relatively suddenly; spondylosis is the broader, slower wear process, although the two can occur together. Spondylosis most often affects the neck and lower back because these areas move and bear load the most. It is one of the most common spinal conditions seen in Singapore, particularly in older adults and those with physically demanding work.
Symptoms & signs
Symptoms vary widely and many people have none. When present, they may include:
- Neck or lower back stiffness, often worse in the morning or after sitting still
- A dull ache that eases with gentle movement and worsens with prolonged activity
- Reduced flexibility in the neck or back
- Pain, numbness or tingling spreading into an arm (cervical) or leg (lumbar)
- Weakness in a limb if a nerve is compressed
- A grinding or clicking sensation with movement
Causes & risk factors
The main cause of spondylosis is age-related wear of the discs and spinal joints. Factors that can contribute or speed it up include:
- Increasing age – the strongest factor
- Previous neck or back injuries
- Repetitive heavy lifting or physically demanding work
- Prolonged poor posture, including long hours at a desk or on devices
- A family history of spinal degeneration
- Smoking, which can affect disc health
How it's diagnosed
Diagnosis begins with a history and physical examination, checking your range of movement, reflexes, sensation and muscle strength to look for any nerve involvement. Imaging is used to confirm the diagnosis and assess severity:
- X-rays – show disc narrowing, bony spurs and joint changes
- MRI scan – shows the discs, nerves and spinal cord in detail and is used when nerve compression is suspected
- CT scan – sometimes used to assess bony detail
- Nerve conduction studies – occasionally used to assess affected nerves
Because spondylosis changes are so common on scans, doctors interpret imaging alongside your actual symptoms.
Treatment options
Most people with spondylosis are managed without surgery. Conservative treatment aims to relieve pain and maintain function:
- Exercise and physiotherapy – to strengthen supporting muscles and improve posture and flexibility
- Pain relief – simple analgesics or anti-inflammatory medicines, used as advised
- Activity and posture changes – ergonomic adjustments and pacing of activity
- Injections – targeted steroid injections in selected cases of nerve-related pain
Surgery is considered only for a minority – typically when there is significant nerve or spinal cord compression with worsening weakness, persistent disabling pain, or other red-flag signs. Because treatment ranges from physiotherapy to specialised spinal surgery, costs vary too widely to quote a single meaningful figure; ask your clinic or hospital for an estimate based on your specific plan, and note that any inpatient spinal surgery may have MediSave and insurance coverage you should confirm in advance.
When to see a doctor & which specialist
See a doctor if neck or back pain is persistent, is getting worse, disturbs your sleep, or spreads into an arm or leg with tingling or weakness. An orthopaedic surgeon (or spine specialist) can assess the spine, arrange imaging and guide treatment, which usually starts with non-surgical care.
Seek urgent medical attention – go to A&E if you develop new or worsening weakness or numbness in the arms or legs, problems with balance or walking, or any change in bladder or bowel control (such as difficulty passing urine or loss of control). These can signal serious compression of the spinal cord or nerves and need emergency assessment; call 995 if symptoms come on suddenly and severely.
For assessment of neck or back spondylosis, find a specialist through our directory of orthopaedic surgeons in Singapore.
