Lumbar Spinal Stenosis Assessment
Spinal stenosis means the space around the nerves in the lower back has become narrow. Many patients notice pain, heaviness or numbness in the legs after walking or standing, which eases when they sit or lean forward.
When to seek assessment
- Walking distance is getting shorter
- Symptoms continue despite medication or physiotherapy
- MRI shows a narrow canal, and you want to understand what it means
- Leg weakness, foot drop or falls
What consultation may involve
- Examination of strength, reflexes, sensation and walking
- MRI review, and correlation with your symptoms
- Discussion of monitoring, exercise, medication, injections and surgery
- Advice on symptoms that need urgent attention
Treatment planning
Possible treatment categories
Narrowing on MRI is common with age, and many people with narrowing have mild or no symptoms. Treatment depends on how much the symptoms affect your life, your examination, the level and degree of narrowing, your general health and your goals. Options may include observation, guided walking and physiotherapy, medication, injections, or surgery to make more room for the nerves.
This page is for education only. A treatment plan requires consultation, clinical examination, and imaging review. If you have sudden weakness, severe headache, loss of consciousness, seizure, or loss of bladder/bowel control, please go to the Emergency Department immediately.
FAQ
Common questions
Is spinal stenosis the same as a slipped disc?
No. A slipped disc is a bulge of disc material pressing on a nerve. Stenosis is a general narrowing of the canal, often from wear in the joints, ligaments and discs. They can occur together.
Will I always need surgery?
No. Many patients are managed without surgery. Surgery is considered when symptoms limit daily life despite other treatment, or when there is weakness that is getting worse.
How is surgery done?
The aim is to decompress the nerves by removing the part of the bone, ligament or disc that is crowding them. This can sometimes be done through a small access route, and sometimes needs a larger approach. Fusion is considered only if the spine is unstable. The method depends on your scan and examination.
Is surgery safe at an older age?
Age alone does not decide this. Heart, lung and kidney health, diabetes, blood thinners and fitness are reviewed first. Risks include infection, bleeding, nerve or dural injury, and symptoms that do not improve fully. These are discussed in detail before any decision.
Clinical context
How leg symptoms are assessed
Leg pain on walking can come from the spine, from narrowed leg arteries, or from nerve problems elsewhere. The examination and imaging are used to tell them apart.
Common causes considered
- Central canal narrowing from thickened ligament and joint overgrowth
- Narrowing where the nerve exits the spine
- Slipped disc together with narrowing
- Reduced leg blood flow, which can feel similar
What to bring
- MRI lumbar spine images and report, preferably the actual disc or digital images
- Previous X-rays, CT scans, nerve tests and physiotherapy notes
- A short note of how far you can walk before symptoms start
- Your medicine list, including blood thinners
Symptoms that appear suddenly, such as new leg weakness, numbness around the groin or saddle area, or loss of bladder or bowel control, need Emergency Department assessment on the same day.
