What is a foraminotomy?

A foraminotomy is a type of spine surgery that aims to widen the foramina of the spine, which are the narrow funnels through which nerve roots exit the spinal canal.

When certain spine conditions, such as spinal stenosis, cause the foramina to narrow, the nerve roots can become compressed, resulting in pain and other symptoms of discomfort. This often occurs in the lumbar spine (lower back), though it may occur in the cervical spine (neck) as well.

The purpose of a foraminotomy is to widen one or more foramina by removing a portion of the spine that is damaged or out of alignment and causing the walls of the foramina to narrow. For example, if a disc in the spine bulges and moves into the spinal canal, the space for the nerve roots to travel out of the canal becomes narrowed. The foraminotomy surgery would remove a portion of the bulging disc in order to maintain adequate space in the foramina for the nerve roots to travel without getting pinched.

Types of surgery available

There are two different surgical approaches for widening the foramina — minimally invasive surgery and open spine surgery. While the goal of a foraminotomy is to remove as little tissue as possible and thus protect the structural integrity of the spine, the open spine approach involves a larger amount of bone and tissue removal. In either case, before closing the incision, surgeons may deem it necessary to perform a spinal fusion to increase stability in the spinal column.

During a traditional foraminotomy, the surgeon will make a large incision in the back that detaches the muscles surrounding the spine. This highly invasive approach to the spine increases the risk for infection, complications and excessive blood loss. Once the spine is accessed, the surgeon will remove either a small portion of spinal material or an entire damaged disc or vertebra to widen the foraminal canal. If the entire disc is removed, the surgeon will insert a small metal cage to fuse together the two surrounding vertebrae and stabilize the spine.

This type of fusion limits mobility in the affected area of the spine and increases the risk of failed back surgery syndrome should the body reject the metal fusion.

Laser Spine Institute’s approach

Laser Spine Institute performs outpatient foraminotomy surgeries through a minimally invasive approach. During the procedure, the surgeon accesses the spine through a small incision and muscle-sparing techniques. Once the surgeon reaches the spine, he or she will remove a small portion of the damaged disc or vertebra. In more severe cases, the surgeon may remove the entire damaged disc, replacing it with a bone graft.

Our minimally invasive techniques reduce the risk of complications and recovery time associated with traditional open back surgical approaches to foraminotomy and foraminectomy.^
