Foraminotomy Surgery
Houston Methodist spine surgeons perform foraminotomy, a minimally invasive spine surgery (MISS) used to relieve nerve compression caused by narrowing of the foramen — the bony opening through which spinal nerve roots exit the spine. This targeted procedure focuses on freeing a compressed nerve while preserving as much of the surrounding spinal structure as possible.
At Houston Methodist, foraminotomy is not a first‑line treatment. Surgery is considered only when non-surgical care has not relieved symptoms and imaging confirms a specific source of nerve compression. Our orthopedic spine surgeons and neurosurgeons work together to evaluate whether foraminotomy — or another surgical or non-surgical approach — best fits your condition, anatomy and long‑term goals. When appropriate, minimally invasive or endoscopic techniques may be used to support precision and recovery.
What Is Foraminotomy?
Foraminotomy is a minimally invasive surgical procedure that enlarges the nerve exit opening (foramen) to relieve pressure on a compressed nerve root and improve symptoms such as pain, numbness or weakness. It is most often used to treat foraminal stenosis and related nerve compression conditions in the cervical (neck) and lumbar (lower back) spine.
Why Choose Houston Methodist for Foraminotomy
Houston Methodist spine specialists combine advanced surgical and minimally invasive techniques with careful, patient‑centered decision‑making. Our orthopedic spine surgeons and neurosurgeons collaborate to determine when foraminotomy is appropriate — and when other treatments may better support long‑term outcomes.
Our goal is to help you move with less pain, preserve function and feel confident in your care plan.

Foraminotomy Success Rates
Foraminotomy can provide meaningful symptom relief when nerve compression is localized, though outcomes depend on the underlying condition and whether additional spinal issues are present. Many patients experience improvement in nerve‑related pain, numbness and weakness following recovery.
Success depends on careful patient selection and the underlying cause of nerve compression. While complications are relatively uncommon due to the targeted and minimally invasive nature of the procedure, symptom relief may be limited if nerve compression is caused by widespread instability or multiple spinal levels.
If symptoms are caused by multiple spinal issues — such as instability or widespread degeneration — foraminotomy may relieve nerve pressure but may not address all sources of pain.
How Does Foraminotomy Work?
Foraminotomy is typically performed under general anesthesia using a posterior (back‑of‑the‑body) approach. During the procedure, your surgeon removes small amounts of bone, tissue or disk material compressing the nerve, often using minimally invasive or endoscopic techniques to reduce disruption to surrounding muscles.
Tubular retractors or endoscopic techniques may be used to minimize disruption to surrounding muscles and soft tissue. By enlarging the nerve exit pathway, foraminotomy can relieve pressure and improve nerve function while maintaining overall spinal stability.
Foraminotomy is often chosen when nerve compression is localized and spinal stability is intact, allowing surgeons to relieve symptoms without removing larger portions of bone or permanently fusing the spine.
Types of Foraminotomy
There are two primary types of foraminotomy, based on the location of the nerve compression within the spine.Cervical Foraminotomy
Cervical foraminotomy is performed in the neck to relieve nerve root compression that causes arm pain, numbness or weakness. It is commonly used to treat conditions such as bone spurs or herniated disks in the cervical spine.
This procedure is typically performed through a posterior approach (back‑of‑the‑body) using microscopic guidance to precisely remove bone and relieve pressure. Many patients experience meaningful symptom relief, though recovery timelines and the degree of improvement vary by individual.
Lumbar Foraminotomy
Lumbar foraminotomy is performed in the lower back to relieve nerve root compression that causes leg pain, often referred to as sciatica, as well as numbness or weakness. It is commonly used to treat lumbar foraminal stenosis, bone spurs or herniated disks in the lumbar spine.
This procedure is typically performed using minimally invasive techniques to relieve pressure while preserving spinal stability. Recovery is often faster than more extensive spine surgeries, though symptom improvement and recovery timelines vary by patient.
What Conditions Does Foraminotomy Treat?
Foraminotomy may be used to treat spinal conditions that cause narrowing of the foramen and nerve compression when non-surgical treatment options have not provided adequate relief. In many cases, patients continue with non-surgical care until symptoms, function or stability change enough to warrant surgery.
Bone Spurs
Bone spurs may develop due to age‑related degeneration and narrowing of the foramen. Foraminotomy can remove these bony overgrowths to relieve nerve pressure.
Degenerative Disk Disease
Degenerative disk disease is a common, age‑related condition in which spinal disks gradually lose their shock‑absorbing ability. Symptoms can include back or neck pain, radiating pain, numbness and reduced flexibility. Physical therapy and pain management are typically first‑line treatments before surgical decompression such as foraminotomy is considered.
Foraminal Stenosis
Foraminal stenosis occurs when the openings where nerves exit the spine become narrowed, placing pressure on nerve roots. Symptoms can include radiating pain, numbness and weakness. Foraminotomy directly enlarges the affected opening to relieve pressure.
Herniated Disk
A herniated disk can extend into the foramen and compress nearby nerves, causing localized or radiating pain. Foraminotomy can remove the portion of the disk responsible for compression while preserving surrounding structures.
Radiculopathy
Radiculopathy refers to symptoms caused by nerve root compression, including pain, tingling or weakness in the arms or legs. In the lower back, this is often called sciatica. Foraminotomy addresses the underlying compression to relieve these symptoms.
Spondylosis
Spondylosis is arthritis of the spine, also known as osteoarthritis of the spine. This common type of arthritis affects joints and disks in both the neck and back.
Who Qualifies for Foraminotomy?
Foraminotomy is typically considered only after a confirmed diagnosis of nerve compression and conservative, non-surgical treatments — such as physical therapy, pain management, medication or injections — have not adequately relieved symptoms.
Your care team will review your treatment history and imaging tests such as MRI or CT scans to confirm narrowing of the foramen and identify the source of symptoms. Foraminotomy is most often recommended for patients with localized nerve compression, rather than widespread spinal instability or deformity. Your surgeons will determine whether foraminotomy is the safest and most durable option — or whether another approach may be more appropriate.
Preparing for Foraminotomy
Preparation begins before the procedure. Your doctor may recommend steps such as:
- Doing pre‑surgical strengthening or conditioning exercises
- Avoiding smoking, vaping or other tobacco use
- Adjusting medications, including blood thinners
- Arranging a home support system, including help with transportation, meals and daily activities
- Planning for post‑surgical support
- Eating a healthy, protein‑rich diet
- Showering with antimicrobial soap before surgery to prevent infection
- Avoiding food and drink after midnight before the procedure
Recovering From Foraminotomy
Many minimally invasive foraminotomy procedures are performed on an outpatient basis or require only a short hospital stay. Many patients can return to light activity within one to two weeks, with recovery generally faster than more extensive spine surgeries, although timelines vary based on the procedure and individual factors.
Walking regularly supports circulation and healing. Avoid bending, lifting and twisting during early recovery. Physical therapy often plays an important role in restoring strength and mobility, and your doctor will guide you through activity restrictions and pain management.
Recovery timelines can differ slightly depending on whether the procedure is performed in the neck or lower back, as well as the underlying condition being treated.
