Foraminotomy

Visit our Specialty Center

Foraminotomy is a minimally invasive spine surgery performed to relieve pressure on spinal nerves that are compressed as they exit the spinal canal through openings called foramina. When these openings become narrowed—often due to age-related changes, disc degeneration, or arthritis—patients can experience pain, numbness, tingling, or weakness that radiates from the neck or back into the arms or legs.

At New Jersey Brain and Spine, foraminotomy is commonly used to treat nerve compression caused by spinal stenosis, herniated discs, and degenerative disc disease. By removing bone or tissue that is narrowing the foramen, this procedure can reduce nerve irritation while preserving as much of the natural spine structure as possible.

What Is a Foraminotomy?

A foraminotomy is a surgical procedure that widens the neural foramen, the small passageways where spinal nerves exit the spinal column. Over time, these openings can become narrowed by bone spurs, thickened ligaments, scoliosis, or bulging discs, leading to painful nerve compression.

Unlike spinal fusion procedures, foraminotomy does not stabilize or fuse the spine. Instead, it focuses on targeted decompression, making it an effective option for patients whose primary issue is nerve impingement rather than spinal instability. According to national estimates, millions of Americans experience symptoms of nerve compression each year, and decompression procedures like foraminotomy are among the most frequently performed spine surgeries in the U.S. More data on these procedures is available through the NIH.

How Is Foraminotomy Performed?

Foraminotomy is typically performed under general anesthesia. Depending on the location of nerve compression, the procedure may be done in the cervical (neck), thoracic (mid-back), or lumbar (lower back) spine.

During the procedure, the surgeon:

• Makes a small incision over the affected spinal level
• Uses specialized instruments and magnification to access the spine
• Removes bone spurs, thickened tissue, or disc material narrowing the foramen

In many cases, minimally invasive techniques are used to limit muscle disruption. The surgery usually takes one to two hours, and most patients go home the same day or after a short hospital stay. Recovery times vary, but many patients return to light activities within a  week, with continued improvement over the following months. Additional procedural overviews are available from the Mayo Clinic.

When Is Foraminotomy Recommended?

Foraminotomy is recommended when symptoms such as radiating arm or leg pain, numbness, or weakness are clearly linked to spinal nerve compression seen on imaging studies—and when non-surgical treatments such as physical therapy, medications, or injections have not provided adequate relief. It is often considered when decompression is needed without the added complexity of spinal fusion.

What Patients Are Good Candidates for Foraminotomy?

Patients who may be good candidates for foraminotomy include those who:

• Have nerve pain caused by spinal stenosis or bone spurs
• Experience arm or leg symptoms from a herniated disc
• Have localized nerve compression without spinal instability
• Have persistent symptoms despite conservative treatment
• Want a minimally invasive option that preserves spinal motion

Risks and Benefits of Foraminotomy

Foraminotomy is designed to relieve nerve pressure while minimizing impact on the surrounding spine.

Potential benefits include:

• Targeted nerve decompression
• Relief of radiating arm or leg pain
• Preservation of spinal motion
• Smaller incisions and faster recovery compared to open surgery

Potential risks include:

• Infection or bleeding
• Nerve irritation or injury
• Incomplete symptom relief
• Recurrence of nerve compression over time

Your NJBS specialist will review your imaging and symptoms to determine whether foraminotomy is the most appropriate treatment.

Case Study: Successful Foraminotomy

A 55-year-old patient with lumbar spinal stenosis came to New Jersey Brain and Spine with severe leg pain and numbness that worsened with walking. Imaging revealed nerve compression caused by bone spurs narrowing the spinal foramen. Because there was no spinal instability, fusion surgery was not recommended.

The NJBS team performed a minimally invasive foraminotomy to relieve pressure on the affected nerve. Within weeks, the patient reported significant pain relief and improved walking tolerance. At the six-month follow-up, the patient had returned to normal daily activities without recurring symptoms. More recovery stories can be found on our patient stories page.
