Introduction
Spinal stenosis is a condition that can gradually affect your ability to walk, exercise, work and enjoy everyday activities. It occurs when the spaces within the spine become narrower, potentially putting pressure on the spinal cord or the nerves travelling through the spine.
For some people, spinal stenosis causes little or no discomfort. For others, it can lead to persistent back or neck pain, numbness, weakness and difficulty walking.
At London Spine Health, we take a personalised approach to spinal conditions, helping patients understand the cause of their symptoms and identify the most appropriate treatment — from conservative management through to advanced minimally invasive and robotic spine surgery.
What Is Spinal Stenosis?
Spinal stenosis occurs when the spinal canal or the openings through which the nerves pass become narrowed.
The spine is made up of individual vertebrae separated by discs, with the spinal cord and nerve roots protected within and around these structures. As we age, changes such as disc degeneration, arthritis, thickened ligaments and bone spurs can gradually reduce the available space.
When the narrowing becomes significant, it can compress the nerves and cause symptoms.
Spinal stenosis most commonly develops in the lower back, known as lumbar spinal stenosis, or in the neck, known as cervical spinal stenosis.
What Causes Spinal Stenosis?
Age-related changes are one of the most common causes of spinal stenosis. However, several other factors can contribute to narrowing of the spinal canal.
Common causes include:
- Age-related degeneration of the spine
- Osteoarthritis and facet joint enlargement
- Bulging or herniated discs
- Thickening of spinal ligaments
- Bone spurs
- Spondylolisthesis
- Previous spinal injury or surgery
- Scoliosis or other spinal deformities
- A naturally narrow spinal canal
In some people, several of these changes occur at the same time, gradually reducing the space available for the nerves.
Symptoms of Lumbar Spinal Stenosis
Lumbar spinal stenosis affects the lower back and can cause symptoms in the legs and feet.
Common symptoms include:
- Lower back pain
- Pain travelling into the buttocks or legs
- Numbness or tingling in the legs
- Leg weakness
- A heavy or tired feeling in the legs
- Difficulty standing for prolonged periods
- Difficulty walking longer distances
- Symptoms that improve when sitting or leaning forwards
One particularly characteristic symptom is neurogenic claudication. Patients may find that walking or standing causes increasing pain, heaviness or weakness in the legs, while sitting down or bending forwards provides relief.
This can significantly affect an individual’s independence and quality of life.
Symptoms of Cervical Spinal Stenosis
When stenosis occurs in the neck, it can potentially affect the spinal cord as well as individual nerve roots.
Symptoms may include:
- Neck pain or stiffness
- Pain travelling into the shoulders or arms
- Numbness or tingling in the hands
- Weakness in the arms or hands
- Difficulty with fine hand movements
- Changes in balance or walking
- Feeling unsteady
- Increased difficulty with everyday tasks
Cervical spinal stenosis can sometimes cause cervical myelopathy, where compression of the spinal cord leads to neurological symptoms. This requires specialist assessment.
When Should You See a Spine Specialist?
Occasional back or neck discomfort does not necessarily mean you have spinal stenosis. However, persistent or progressive symptoms should not be ignored.
You should consider specialist assessment if you experience:
- Increasing difficulty walking
- Persistent numbness or tingling
- Weakness in your arms or legs
- Pain that repeatedly returns when standing or walking
- Loss of balance
- Difficulty with hand coordination
- Symptoms that interfere with sleep, work or daily activities
If you develop new bladder or bowel problems, significant weakness or numbness around the groin or inner thighs, seek urgent medical attention.
How Is Spinal Stenosis Diagnosed?
An accurate diagnosis begins with a detailed medical history and physical examination.
Your specialist may recommend imaging such as:
MRI: Provides detailed images of the discs, nerves, spinal cord and other soft tissues.
CT scan: Provides detailed information about the bones and can help identify bone spurs and structural narrowing.
X-rays: Can help assess spinal alignment, degeneration and movement between vertebrae.
The results of your examination and imaging are considered together rather than relying on a scan alone. This helps determine whether the narrowing seen on an image is actually responsible for your symptoms.
How Is Spinal Stenosis Treated?
Treatment depends on the severity of your symptoms, the underlying cause and whether nerves or the spinal cord are being compressed.
For patients with mild or moderate symptoms, treatment may initially include:
- Physiotherapy
- Targeted strengthening exercises
- Activity modification
- Appropriate pain relief
- Weight management where appropriate
- Postural advice
- Image-guided spinal injections in selected cases
These approaches can help reduce symptoms and improve mobility without surgery.
When Is Surgery Recommended?
Surgery may be considered when symptoms are severe, progressively worsening or have not responded adequately to non-surgical treatment.
Surgical treatment aims to decompress the affected nerves or spinal cord and, where necessary, stabilise the spine.
Depending on the patient’s condition, procedures may include:
- Decompression surgery
- Laminectomy
- Foraminotomy
- Spinal fusion
- Minimally invasive spinal surgery
- Robotic-assisted spinal surgery in appropriate cases
The goal is not simply to treat an MRI finding, but to address the structural problem responsible for the patient’s symptoms.
Minimally Invasive and Robotic Spine Surgery
Advances in spinal surgery mean that some patients can now undergo procedures using minimally invasive techniques.
Smaller surgical approaches can reduce disruption to surrounding tissues and may help support a faster recovery in appropriately selected patients.
Robotic and computer-assisted navigation can also assist the surgeon with planning and implant positioning during certain spinal procedures.
However, robotic surgery is not automatically better for every patient. The most appropriate technique depends on the individual’s diagnosis, anatomy and surgical requirements.
Can Spinal Stenosis Be Prevented?
Not every case of spinal stenosis can be prevented, particularly when age-related degeneration is involved. However, maintaining good spinal health may help reduce unnecessary strain on your back and neck.
Regular physical activity, maintaining a healthy weight, strengthening the muscles supporting your spine, avoiding smoking and using appropriate lifting techniques can all contribute to long-term spinal health.
Most importantly, persistent neurological symptoms should be assessed rather than ignored.
Take the Next Step Towards Better Spinal Health
Living with spinal stenosis does not mean you have to accept ongoing pain or reduced mobility.
The right treatment depends on the individual. Some patients can manage their symptoms successfully without surgery, while others may benefit from advanced decompression or minimally invasive spinal procedures.
At London Spine Health, specialist assessment can help identify the cause of your symptoms and establish a treatment plan designed around your condition, lifestyle and recovery goals.
