Thoracic Spinal Stenosis: Understanding Laminectomy and Fusion Surgery

Understanding Thoracic Spinal Stenosis

What Makes Thoracic Stenosis Different?

Your thoracic spine is the middle section of your back where your ribs attach. This area is naturally more stable than your neck or lower back because of the rib cage, which is why stenosis here is less common but can be more complex to treat.

Thoracic spinal stenosis occurs when the spinal canal – the tunnel that houses your spinal cord – becomes narrowed in this mid-back region. This narrowing can compress the spinal cord or nerves, leading to a unique pattern of symptoms that often confuse both patients and doctors.

What This Feels Like to Patients?

Common symptoms include:

• Band-like chest pain that wraps around your ribs

• Burning or electric sensations in your torso

• Walking difficulties or leg weakness

• Balance problems that worsen with activity

• Numbness or tingling that follows your ribs around to the front

• Muscle spasms in your back or chest area

In severe cases:

• Bladder or bowel control problems (this requires immediate medical attention)

• Significant leg weakness affecting mobility

What makes this confusing: These symptoms can mimic heart problems, lung issues, or abdominal conditions, which is why thoracic stenosis is often diagnosed later than other spine problems.

What Causes Thoracic Stenosis?

Most common causes:

• Age-related changes – thickening ligaments, bone spurs, disc bulging

• Arthritis of the spine joints

• Previous spinal injuries or fractures

• Genetic factors leading to naturally narrow spinal canals

Less common causes:

• Spinal tumours or cysts

• Inflammatory conditions like rheumatoid arthritis

• Previous spine surgery complications

Advanced Diagnosis at MIRSS

Diagnosing thoracic stenosis requires specialised evaluation because symptoms can be misleading:

• Comprehensive neurological examination to identify specific patterns of nerve involvement

• High-resolution MRI scans to visualise spinal cord compression and signal changes

• CT scans, if needed, to assess bone structure and calcification

• CT myelogram in complex cases to better define spinal cord compression

• 3D imaging reconstruction for precise surgical planning

This thorough evaluation helps determine not only the presence of stenosis but also the severity of spinal cord compression and the best treatment approach.

Treatment Options: From Conservative to Surgical

Conservative Treatment First

Many patients with mild to moderate thoracic stenosis can be managed without surgery:

Non-surgical approaches:

• Anti-inflammatory medications to reduce swelling and pain

• Physical therapy focusing on posture, core strengthening, and flexibility

• Activity modification to avoid positions that worsen symptoms

• Injections in the spine to reduce inflammation around nerves

• Bracing in specific cases to support the spine

When conservative treatment works:

• Symptoms remain manageable

• Function is maintained or improved

• Pain doesn't significantly interfere with daily activities

When Surgery Becomes Necessary?

Surgery may be recommended when:

• Progressive neurological symptoms such as increasing leg weakness

• Spinal cord compression is visible on MRI scans

• Severe pain that doesn't respond to conservative treatment

• Walking difficulties that significantly impact quality of life

• Bladder or bowel dysfunction (this is a surgical emergency)

Surgical Options: Laminectomy and Fusion

Thoracic Laminectomy: Creating Space

What it involves: A Laminectomy removes the lamina (the roof of the spinal canal) to create more space for the compressed spinal cord and nerves.

When laminectomy alone is sufficient:

• Single-level stenosis

• Good spinal stability

• No significant deformity

• Younger patients with good bone quality

When Fusion Becomes Necessary?

Spinal fusion is often added to a laminectomy in thoracic stenosis because:

• The thoracic spine relies on bone structure for stability

• Removing bone can create instability

• Multiple levels often need treatment

• Prevention of future problems at treated levels

Laminectomy with fusion involves:

• Decompression: Removing bone and ligament to relieve pressure

• Stabilisation: Placing screws and rods to support the spine

• Fusion: Adding a bone graft to permanently connect the vertebrae

Factors Determining the Approach

Laminectomy alone may be considered when:

• Single-level involvement

• Excellent bone quality

• No pre-existing instability

• Minimal bone removal required

Fusion is typically needed when:

• Multiple levels are involved

• Significant bone removal is required

• Pre-existing instability exists

• Previous spine surgery at the same levels

The Surgical Process at MIRSS

Before Surgery

Your surgical team will:

• Create detailed 3D surgical plans using robotic planning software

• Review your specific stenosis pattern and spinal cord compression

• Discuss the procedure and expected outcomes with our dedicated spine anesthesia team

During Surgery

The procedure typically takes 2-4 hours, depending on the number of levels:

• Anaesthesia: Our specialised spine anaesthesia team provides comprehensive care throughout the procedure.

• Positioning: Careful face-down positioning to optimise surgical access while protecting all pressure points.

• Robotic-Guided Decompression: Precise removal of lamina and any compressive elements using robotic navigation.

• Spinal Cord Assessment: Direct visualisation to ensure adequate decompression.

• Fusion (when needed): Robotic-guided placement of screws and rods for stabilisation.

• Bone Grafting: Placement of bone graft material to promote fusion.

• Neuromonitoring: Intraoperative neuromonitoring continuously tracks spinal cord function throughout the procedure.

• Final Verification: Comprehensive imaging to confirm adequate decompression and proper hardware placement.

Our specialized OR staff experienced in thoracic spine procedures coordinate throughout this complex surgery.

Recovery: What to Expect

In the Hospital

• Most patients stay 2-3 days after surgery (depends on patient to patient)

• Pain management with multimodal approaches

• Early mobilization with physical therapy guidance

• Respiratory therapy to prevent pneumonia

• Monitoring for any complications

Recovery Timeline

First 2 Weeks:

• Initial wound healing

• Gradual increase in walking

• Pain management and medication adjustment

• Follow-up appointment for wound check

Weeks 2-8:

• Progressive activity increase

• Beginning of formal physical therapy

• May require thoracic brace for support

• Continued restrictions on lifting and twisting

Months 2-6:

• Laminectomy patients: Progressive strengthening, return to most activities

• Fusion patients: Ongoing fusion healing, gradual activity increase

• Regular follow-up to monitor healing progress

6+ Months:

• Laminectomy patients: Full activity as appropriate
