Lumbar spinal canal stenosis is one of the most common causes of lower back pain and leg discomfort in adults over 50. It occurs when the spinal canal narrows and compresses the nerves passing through the lower back. At Samobathi Pain Clinic, we offer evidence-based, minimally invasive interventional treatments that effectively relieve symptoms of lumbar spinal canal stenosis without requiring open surgery.
What Is Lumbar Spinal Canal Stenosis?
Lumbar spinal canal stenosis refers to narrowing of the spinal canal in the lower back. This narrowing compresses the nerve roots or the cauda equina, leading to pain, numbness, leg heaviness, and difficulty walking.
The condition develops gradually due to age-related degeneration, arthritis, disc bulging, or ligament thickening. Many patients experience relief when bending forward or sitting, which is a hallmark sign of lumbar spinal canal stenosis.
Causes of Lumbar Spinal Canal Stenosis
Several structural changes can lead to lumbar spinal canal stenosis, including:
1. Degenerative Disc Disease
Worn-out discs reduce space for nerves.
2. Bone Overgrowth (Osteophytes)
Arthritic changes create bone spurs that narrow the spinal canal.
3. Thickened Ligamentum Flavum
This ligament can hypertrophy and compress nerve roots.
4. Lumbar Facet Joint Hypertrophy
Enlarged joints reduce spinal canal diameter.
5. Lumbar Spondylolisthesis
Forward slip of one vertebra over another compresses the canal.
6. Spinal Congenital Narrowing
Some individuals are born with naturally narrow spinal canals.
7. Disc Herniation
A bulging disc can significantly narrow the canal.
Symptoms of Lumbar Spinal Canal Stenosis
Common symptoms of lumbar spinal canal stenosis include:
Lower back pain
Leg pain, numbness, or tingling
Weakness in legs
Cramping or tightness in calves
“Heaviness” or fatigue in the legs
Difficulty standing or walking long distances
Relief on bending forward (shopping cart sign)
As the condition progresses, symptoms worsen during walking and improve while resting.
Diagnosis of Lumbar Spinal Canal Stenosis
At Samobathi Pain Clinic, diagnosis includes:
Detailed medical history
Neurological examination
Gait analysis and posture evaluation
MRI lumbar spine — gold standard for diagnosing lumbar spinal canal stenosis
X-rays to detect degenerative changes
Electrophysiological tests when required
Accurate diagnosis helps design the most effective interventional pain management plan.
Treatment Options for Lumbar Spinal Canal Stenosis at Samobathi Pain Clinic
Treatment for lumbar spinal canal stenosis depends on severity, duration, and functional limitations. We begin with conservative measures and progress to advanced interventional options when needed.
Conservative Treatment for Lumbar Spinal Canal Stenosis
Mild to moderate cases may improve with:
Physiotherapy and flexion-based exercises
Core strengthening
Anti-inflammatory medications
Neuropathic pain medications
Activity modification
Lifestyle and posture correction
Patients with persistent leg pain or walking difficulty often benefit most from interventional treatments.
Interventional Pain Management for Lumbar Spinal Canal Stenosis
Interventional pain procedures help decompress nerves, reduce inflammation, and restore mobility.
1. Epidural Steroid Injection (ESI)
Reduces inflammation around compressed nerves.Suitable for central and foraminal stenosis.
2. Transforaminal Epidural Steroid Injection (TFESI)
Highly targeted procedure delivering medication directly to the affected nerve root.Effective for radicular symptoms associated with lumbar spinal canal stenosis.
3. Caudal Epidural Injection
Useful for multi-level stenosis or post-surgical cases.
4. Interlaminar Epidural Injection
Best suited for central canal narrowing.
5. Facet Joint Injection
Facet hypertrophy contributes to stenosis—facet injections reduce local inflammation.
6. Radiofrequency Ablation (RFA)
For chronic facet-mediated back pain associated with stenosis.
7. Percutaneous Minimally Invasive Decompression
Procedures such as:
Ligamentum flavum debulking
Foraminal decompression
Endoscopic decompression (when indicated)
These options are less invasive alternatives to open surgery.
8. Spinal Cord Stimulation (SCS)
For chronic neuropathic pain and neurogenic claudication in selected patients who are not surgical candidates.
When Is Surgery Considered?
Surgery is recommended in severe cases of lumbar spinal canal stenosis, such as:
Progressive leg weakness
Severe neurogenic claudication
Cauda equina symptoms
Persistent pain despite interventional therapy
Most patients improve significantly with non-surgical treatments when started early.
Preventing Lumbar Spinal Canal Stenosis
Strategies include:
Regular exercise
Healthy posture
Maintaining body weight
Strengthening core and back muscles
Avoiding prolonged standing or heavy lifting
Using ergonomic furniture
Lifestyle modification greatly helps prevent symptom progression.
