A lumbar laminectomy is designed to relieve pressure on the nerves in the lower back caused by spinal stenosis.

Common symptoms include:

• Difficulty standing upright for long periods

• Leg heaviness or fatigue when walking

• Numbness or tingling in the legs

• Pain that improves when sitting or bending forward

• Reduced walking distance due to discomfort

The goal of surgery is to remove the arthritic tissue and bone that are narrowing the spinal canal and pinching the nerves.

Lumbar laminectomy is performed under general anesthesia using a minimally invasive approach.

During surgery:

• A small incision, typically about 2 centimeters, is made in the lower back

• A specialized retractor is placed to access the spine

• A microscope is used to improve visualization and precision

• The arthritic bone and tissue causing the narrowing are removed

• The spinal canal is opened to relieve pressure on the nerves

The procedure typically takes less than one hour, and patients usually return home the same day.

Day of Surgery

• Most patients go home the same day

• Walking is encouraged immediately

First Few Weeks

• Gradually increase activity as tolerated

• Most patients notice improvement in walking and leg symptoms early in recovery

• Some incisional soreness is expected

6-8 Weeks

• Most patients have returned to normal daily activities

• Continued improvements in mobility and endurance are common

Recovery is generally well tolerated and focused on restoring movement and function.

The goal of lumbar laminectomy is to improve symptoms caused by spinal stenosis and help patients return to a more active lifestyle.

Many patients experience:

• Improved walking tolerance

• Reduced leg pain and numbness

• Less heaviness in the legs

• Improved ability to stand upright

• Better overall function and mobility

Most patients notice improvement relatively quickly after surgery.

Every surgery carries risks, though serious complications are uncommon.

During Surgery

• Spinal fluid leak (approximately 2%)

• Nerve injury (rare)

After Surgery

• Fluid collection around the surgical site

• Accumulation of blood or inflammatory fluid

• Approximately 1-2% of patients may require another procedure to remove a fluid collection if symptoms return

In some cases, spinal instability is also present. When that occurs, a lumbar fusion may be recommended along with the laminectomy. Your surgeon will discuss whether both procedures are necessary based on your imaging and symptoms.
