Overview
A laminotomy removes a small part of the lamina, rather than the whole thing. A foraminotomy enlarges the foramen, the opening where a nerve root exits the spine. Both aim to relieve a pinched nerve while keeping as much normal structure as possible.
They are used in both the neck (for example a posterior cervical foraminotomy for arm pain) and the lower back.

Who may be a candidate
- Arm or leg pain from a pinched nerve at a specific level
- Foraminal stenosis or a side-located disc herniation
- Symptoms that have not improved with nonsurgical care
Your exam, imaging and overall health decide whether this surgery is appropriate for you.
How it is done
- General anesthesia; position depends on the level.
- A small incision is made, often with a tubular retractor.
- The surgeon removes a small amount of bone, ligament or disc to free the nerve.
- The incision is closed; many patients go home the same day.
This procedure is often done on an outpatient basis. Procedures that are appropriate for outpatient care may be performed at GSMC’s surgery center; others are done in a hospital. Your surgeon will explain where your procedure would take place.
Recovery timeline
Walking and light activity; limit lifting.
Gradual return to work and normal activity; therapy if advised.
Recovery depends on the procedure, your health and how many levels are treated. Your surgeon will give you a written plan.
Risks
Every surgery has risks. Your surgeon will review them with you, including:
- Infection or bleeding
- Nerve injury
- Spinal fluid leak
- Recurrent symptoms

Frequently asked questions
Is a foraminotomy a fusion?
No. It removes tissue to free a nerve and usually does not require fusion.
Neck or back?
Both. A posterior cervical foraminotomy can treat certain pinched nerves in the neck without fusion.
How long is recovery?
Often a few weeks for daily activities.
