Foraminotomy
What Is a Foraminotomy?
A foraminotomy is a spine procedure that relieves pressure on spinal nerves by enlarging the foramen, which is the small opening where nerves exit the spinal canal. When this opening becomes narrowed, it can compress the nerve and cause pain, numbness, tingling, or weakness.
This narrowing is often caused by bone spurs, herniated discs, or age-related changes in the spine. A foraminotomy removes or reshapes the tissue that is pressing on the nerve, creating more space for it to pass through safely.
Foraminotomy can be performed in the neck (cervical spine) or lower back (lumbar spine), depending on the location of symptoms.
At OIBortho, our physicians evaluate and treat nerve compression conditions, including those that may require foraminotomy, for patients throughout Middlesex, Monmouth, and Ocean Counties.
When Is a Foraminotomy Recommended?
A foraminotomy may be recommended when a spinal nerve is being pinched as it exits the spine and symptoms do not improve with non-surgical treatment.
It may be considered for:
- Foraminal stenosis (narrowing of nerve exit pathways)
- Herniated discs pressing on a nerve root
- Bone spurs (spinal arthritis)
- Cervical or lumbar radiculopathy
- Persistent nerve pain despite conservative care
- Unilateral (one-sided) nerve compression
Symptoms That May Lead to Surgery
Patients who may benefit from a foraminotomy often experience:
- Radiating pain in the arm or leg
- Numbness or tingling in the extremities
- Muscle weakness
- Burning or sharp nerve pain
- Pain that worsens with certain movements
- Symptoms limited to one side of the body
- Reduced function or grip strength
Causes of Foraminal Narrowing
Foraminotomy treats conditions that reduce space in the nerve exit openings, including:
- Degenerative disc disease
- Herniated discs
- Bone spurs (arthritis of the spine)
- Thickened ligaments
- Loss of disc height with aging
- Spondylolisthesis (in some cases)
These changes can gradually compress nerves as they leave the spinal canal.
How the Procedure Works
During a foraminotomy:
- A small incision is made near the affected area of the spine
- Muscles are gently moved aside to access the vertebrae
- Bone or soft tissue compressing the nerve is removed
- The foramen is widened to allow more space for the nerve
- The nerve is decompressed while maintaining spinal stability when possible
The goal is to relieve pressure on the nerve without removing more bone than necessary.
Recovery and What to Expect
Recovery depends on the individual and the extent of the procedure.
Typical recovery may include:
- Gradual improvement in nerve pain
- Walking shortly after surgery
- Temporary restrictions on bending or lifting
- Physical therapy to restore strength and mobility
- Return to normal activities over weeks to months
Many patients notice improvement in radiating nerve symptoms after decompression.
Risks and Considerations
As with all spine procedures, foraminotomy carries some risks, including:
- Infection
- Bleeding
- Nerve irritation or injury (rare)
- Spinal fluid leak (rare)
- Persistent or recurrent symptoms
- Need for additional surgery in some cases
A physician will review all risks and benefits before recommending treatment.

Frequently Asked Questions
What is a foraminotomy?
It is a procedure that creates more space in the foramen where spinal nerves exit the spine.
What conditions does it treat?
It is commonly used for foraminal stenosis, bone spurs, and herniated discs causing nerve compression.
Is it minimally invasive?
It can often be performed using minimally invasive techniques depending on the case.
Will it relieve nerve pain?
It is often effective for relieving radiating arm or leg pain caused by nerve compression.
How long is recovery?
Most patients gradually improve over several weeks, depending on the procedure and individual healing.
Is spinal stability affected?
The procedure is designed to preserve stability whenever possible, but this depends on the extent of decompression needed.
