How common is spinal stenosis?
Spinal stenosis is a relatively common degenerative condition, particularly as people get older. The term refers to a narrowing of spaces within the spine, which can place pressure on the spinal cord or the nerves that travel from it into the arms or legs.
Research suggests that lumbar spinal stenosis affects approximately 21% of adults over the age of 60. While not everyone with narrowing will experience symptoms, this figure highlights how frequently age-related spinal changes occur.
As life expectancy increases, spinal stenosis is becoming an increasingly recognised cause of pain and mobility limitation in older adults.
Why does spinal stenosis become more common with age?
The spine naturally undergoes wear and tear over time. Several structural factors contribute to spinal stenosis including:
- Degenerative disc disease, where disc height loss reduces available space
- Facet joint arthritis, leading to bony overgrowth
- Thickening of spinal ligaments
- Bone spurs that develop as part of arthritic change
- In some cases, a congenitally narrow spinal canal
The lumbar spine, in the lower back, is most commonly affected. Cervical spinal stenosis, which occurs in the neck, can also develop and may affect balance, hand coordination, or arm function if the spinal cord is compressed.
Symptoms of spinal stenosis
Symptoms vary depending on the location and severity of the narrowing. In lumbar spinal stenosis, a classic feature is neurogenic claudication. This describes pain, heaviness, tingling, or weakness in the legs that worsens when standing or walking and improves with sitting or bending forward.
Patients often report that leaning over a shopping trolley or walking uphill feels easier than walking on flat ground. This forward-flexed posture temporarily increases space within the spinal canal and reduces nerve pressure.
In cervical spinal stenosis, symptoms can involve neck pain, arm pain, hand numbness, or in more severe cases, difficulty with balance or fine motor skills.
It’s important to recognise that many people over 60 will show narrowing on MRI scans without experiencing symptoms. Treatment decisions are guided by clinical findings and the impact on quality of life, rather than imaging alone.
Current treatments for spinal stenosis
Treatment depends on symptom severity and functional limitation. Many patients improve with conservative management, particularly in the early stages. Non-surgical options include pain management strategies, and physiotherapy focused on posture, flexibility, and strengthening.
When symptoms are persistent, progressive, or significantly limit walking and independence, minimally invasive surgical options may be considered. Decompression procedures aim to remove the structures causing nerve pressure while preserving as much normal anatomy as possible.
Modern techniques allow for precise decompression through smaller incisions, reducing tissue disruption and supporting recovery.
