Spinal Decompression Surgery

Evaluation and surgical treatment for spinal stenosis, herniated discs, nerve compression, sciatica, arm numbness, walking limitations, and spinal cord compression symptoms.

Spinal decompression surgery is performed to relieve pressure on spinal nerves or the spinal cord when compression causes significant pain, numbness, weakness, or loss of function.

For some patients, symptoms begin gradually with neck pain, lower back pain, or radiating arm and leg symptoms. Others develop progressive numbness, weakness, walking intolerance, balance problems, or difficulty performing normal daily activities.

When nerve compression continues despite conservative treatment, surgical evaluation may help determine whether decompression surgery is appropriate.

Dr. Garges provides spinal decompression surgery evaluation in Webster, TX for patients throughout Clear Lake, League City, Nassau Bay, Friendswood, Pearland, Pasadena, and the greater Houston area.

As a board-certified orthopedic spine surgeon with fellowship training at the San Francisco Spine Institute and prior experience as chief of spinal surgery at UTMB, Dr. Garges evaluates cervical, thoracic, and lumbar spine conditions requiring advanced surgical decision-making.

What Spinal Decompression Surgery Is Designed to Treat

Spinal decompression surgery is intended to relieve pressure on compressed nerves or the spinal cord caused by structural narrowing within the spine.

Nerve compression may develop from:

Spinal stenosis
Herniated discs
Bone spurs
Degenerative disc disease
Thickened spinal ligaments
Foraminal narrowing
Degenerative instability or spondylolisthesis

Compression affecting the cervical spine may cause neck pain, arm symptoms, hand weakness, coordination difficulty, or spinal cord dysfunction.

Compression affecting the lumbar spine commonly causes lower back pain, sciatica, leg numbness, weakness, standing intolerance, or reduced walking capacity.

The goal of decompression surgery is to create additional space around compressed nerves or the spinal cord contributing to pain, neurologic symptoms, and functional limitations.

Not all spinal abnormalities seen on MRI require surgery. Surgical decisions are based on the relationship between symptoms, neurologic findings, physical examination, imaging studies, and response to prior conservative treatment.

Symptoms That May Indicate Significant Nerve Compression

Patients often seek evaluation when symptoms begin interfering with normal daily function, mobility, work activities, or quality of life.

Common symptoms associated with spinal nerve compression include:

Persistent neck pain or lower back pain
Sciatica or pain radiating into the leg
Arm pain, numbness, or tingling
Weakness in the hands, arms, legs, or feet
Burning pain between the shoulder blades
Difficulty standing or walking for extended periods
Loss of balance or coordination
Difficulty holding or gripping objects
Symptoms disrupting sleep
Functional decline affecting work or daily activities

Some patients experience progressive walking limitations caused by lumbar spinal stenosis. Others develop worsening hand coordination, dropping objects, or balance difficulty related to cervical spinal cord compression.

Symptoms may worsen while standing, walking, driving, bending, lifting, or maintaining certain neck positions. In some cases, patients notice gradual neurologic decline over time.

Because symptoms may overlap with shoulder, hip, peripheral nerve, or other musculoskeletal conditions, accurate diagnosis is important before surgical decisions are made.

Conditions Commonly Evaluated for Spinal Decompression Surgery

Several spine conditions may lead to compression of spinal nerves or the spinal cord. Surgical decompression may become a treatment consideration when conservative care no longer provides sufficient relief or when neurologic symptoms progress.

Spinal Stenosis

Spinal stenosis refers to narrowing of the spinal canal or nerve passageways. Degenerative changes associated with aging commonly contribute to stenosis.

Bone overgrowth, thickened ligaments, bulging discs, and degenerative arthritis may narrow the spinal canal and compress neural structures.

Lumbar spinal stenosis commonly causes:

Leg pain while walking
Standing intolerance
Sciatica
Leg weakness or numbness

Cervical spinal stenosis may contribute to:

Arm numbness or weakness
Hand coordination problems
Balance changes
Spinal cord compression symptoms

Herniated Discs

A herniated disc occurs when disc material extends beyond its normal boundary and compresses nearby nerves.

Cervical disc herniation may cause neck pain with radiating arm symptoms. Lumbar disc herniation commonly causes sciatica, leg pain, numbness, or weakness.

Some herniated discs improve with conservative care alone. Others continue causing persistent neurologic symptoms despite therapy, medications, injections, or activity modification.

Foraminal Stenosis and Nerve Root Compression

Foraminal stenosis refers to narrowing of the openings where spinal nerves exit the spine. This narrowing may compress individual nerve roots and produce radiating pain, numbness, or weakness.

Degenerative changes, bone spurs, disc collapse, and arthritis commonly contribute to foraminal narrowing.

Degenerative Instability and Spondylolisthesis

Some patients develop spinal instability in addition to nerve compression. Degenerative spondylolisthesis occurs when one vertebra shifts forward relative to another.

This instability may contribute to spinal canal narrowing and worsening neurologic symptoms during standing or walking.

How Dr. Garges Evaluates Surgical Candidacy

Not every patient with spinal stenosis or disc herniation requires surgery. Determining whether decompression surgery may help requires careful correlation of symptoms, imaging findings, neurologic examination, and prior treatment response.

Dr. Garges performs a comprehensive surgical evaluation that may include:

Evaluation Component	Purpose
Symptom Review	Determines pain patterns, walking limitations, numbness, weakness, and progression of symptoms
Neurologic Examination	Evaluates strength, reflexes, sensation, coordination, and spinal cord function
Imaging Correlation	Determines whether MRI or CT findings match clinical symptoms
Treatment History	Reviews prior therapy, injections, medications, and previous spine procedures
Functional Assessment	Evaluates mobility limitations, walking tolerance, and daily activity impact

Imaging findings alone do not determine treatment. Many patients have spinal stenosis or disc abnormalities visible on MRI scans without significant symptoms.

Dr. Garges focuses on identifying clinically significant compression responsible for the patient’s neurologic symptoms and functional decline.

Patients should bring prior MRI, CT, X-ray studies, imaging reports, and previous treatment records to their evaluation whenever possible.

Types of Spinal Decompression Procedures

Several surgical procedures may be used to decompress spinal nerves depending on the diagnosis, anatomy, severity of compression, and spinal stability.

Laminectomy

Laminectomy involves removing part of the lamina, the bony structure covering the back of the spinal canal. Removing this bone creates more space for the spinal cord and nerves.

Laminectomy is commonly performed for spinal stenosis affecting the cervical or lumbar spine.

In some cases, partial decompression procedures such as laminotomy may be sufficient depending on the extent of narrowing.

Discectomy and Microdiscectomy

Discectomy removes herniated disc material compressing a nerve root.

Microdiscectomy uses magnification and smaller incisions to access the affected nerve. These procedures are commonly performed for herniated discs causing sciatica or cervical radiculopathy.

The goal is to decompress the affected nerve while preserving as much healthy disc structure as possible.

Foraminotomy

Foraminotomy enlarges the opening where a spinal nerve exits the spine. This procedure may be performed when foraminal stenosis compresses a nerve root.

Decompression Combined With Fusion

Some patients require stabilization procedures in addition to decompression surgery.

Fusion may be considered when:

Spinal instability is present
Spondylolisthesis contributes to compression
Extensive decompression could create instability
Degenerative motion contributes to symptoms

Not every decompression procedure requires spinal fusion. Surgical planning depends on the patient’s anatomy, stability, diagnosis, and neurologic findings.

When Spinal Decompression Surgery May Be Considered

Most patients begin with conservative treatment before surgery is considered.

Non-surgical treatment may include:

Physical therapy
Medication management
Activity modification
Epidural steroid injections
Posture and ergonomic changes
Exercise and rehabilitation programs

Many patients improve without surgery.

Surgical evaluation may become appropriate when:

Pain persists despite conservative treatment
Neurologic symptoms progressively worsen
Walking becomes severely limited
Weakness develops
Spinal cord compression affects balance or coordination
Symptoms significantly reduce quality of life

Progressive weakness, worsening neurologic deficits, or spinal cord compression symptoms require prompt evaluation.

Dr. Garges carefully evaluates whether decompression surgery is likely to address the patient’s specific symptoms before discussing surgical recommendations.

Imaging and Surgical Planning

Advanced imaging plays an important role in surgical planning and evaluation of nerve compression.

MRI Evaluation

MRI is the primary imaging study used to evaluate spinal stenosis, herniated discs, nerve compression, and spinal cord involvement.

MRI helps identify:

Disc herniation
Spinal canal narrowing
Nerve root compression
Spinal cord compression
Soft tissue abnormalities

CT and X-Ray Evaluation

CT imaging provides detailed evaluation of bone structures and degenerative changes. X-rays help assess spinal alignment, instability, and motion between vertebrae.

Flexion-extension X-rays may be used when instability is suspected.

These imaging studies help determine:

The location of compression
The severity of stenosis
Whether instability is present
Whether decompression alone or fusion may be appropriate
