Lumbar Laminectomy

What is a Lumbar Laminectomy Surgery?

A lumbar laminectomy is a surgical intervention conducted by a spine specialist aimed at alleviating pressure on a spinal nerve in the lower back. This procedure is also referred to as spinal decompression, as it involves the removal of tissue that is exerting pressure on a nerve. The tissues that can cause nerve compression in the lumbar region may include bone formations, such as osteophytes, and/or disc material, such as herniated discs.

What are the Different Types of Lumbar Laminectomy Surgery?

Lumbar laminectomy can be categorized based on the extent of lamina removal and the method employed to alleviate neural compression. The types include:

Bilateral laminectomy: Removal of the lamina from both sides of the affected vertebra.
Unilateral laminotomy: Removal of either a portion or the entirety of the lamina on one side of the affected vertebra.
Endoscopic unilateral laminotomy: Minimally invasive approach using an endoscope.

In certain cases involving lumbar vertebrae, the facets may be partially or entirely excised, leading to the consideration of vertebral fusion to maintain stability.

Who Needs a Laminectomy?

Laminectomy is typically advised for patients who suffer from symptoms such as pain, weakness, or numbness in the spine, which arise from various spinal conditions that exert pressure on the spinal cord or nerves.

Conditions that may warrant laminectomy include:

Herniated Disc
Spinal Stenosis
Degenerative Spinal Conditions
Spinal Tumours
Injury or Trauma
Ineffectiveness of Conservative Treatments

What are the Symptoms of Lumbar Laminectomy?

Heaviness in the thighs and the buttocks
Pressure in the shoulder blade field
In one leg or both, numbness or pain
Bladder and bowel function issues
Pain has not been helped by physical therapy
Difficulty getting around
Stenosis is demonstrated by diagnostic tests such as MRI and CT.

How is Lumbar Laminectomy Diagnosed?

Your physician will address your medical history and perform a physical examination to diagnose spinal stenosis. To detect the underlying cause, several imaging tests are also required.

Tests on Imaging

MRI: Detects weakened discs, ligaments and tumours.
X-rays: Diagnose potential cause of neck pain, disc degeneration, spondylitis, tumours, and spine curvature.
CT: Produces cross-sectional images to identify growths, tumours, and herniated discs.

How is the Lumbar Laminectomy Procedure Done?

Before Surgery

IV line inserted in the arm
Anaesthesia explained
Full medical history is taken

During Surgery

Incision is made in the back
Muscles and tissues pushed aside
Lamina removed
Facet joints undercut if needed
Decompression performed
Spinal fusion may be done
Wound is stitched

After Surgery

Patient monitored for anaesthesia effects
Pain medication prescribed
Discharge typically within 24 hours
Physical therapy recommended
Avoid strenuous tasks for several months
