What is a laminectomy?michelson=

Dr. Theodore A. Belanger
Charlotte, NC

The word laminectomy refers to removal ("ectomy") of the portion of bone in the spine that covers the nerves ("lamina"). A laminectomy is generally performed to visualize and decompress nerves in the spine, such as in the case of a herniated disc or spinal stenosis.

Dr. Mark Rosenthal
Baltimore, MD

A Laminectomy is a surgical procedure designed to remove the lamina. The lamina is the portion of bone in the back of the spine which covers the spinal cord. A laminectomy is done either to remove the bone itself, such as to treat stenosis, or to get the bone out of the way to do other work, such as removal of a disc herniation.

Dr. W. Christopher Urban
Glen Burnie, MD

A laminectomy is a surgical procedure that involves removing bone (lamina) and soft tissue (ligamentum flavum) that are compressing the nerve roots. Laminectomy is a decompression technique that is most commonly used to treat spinal stenosis.

Dr. Jeffrey Goldstein
New York, NY

Laminectomy is removal of the back side of the spinal canal under which lie the nerve tissues. This provides access to the nerves and the discs for specific treatment. When commonly performed in the "low back" or lumbar spine this may actually be below the level of the spinal cord itself.

Dr. Kenneth A. Pettine
Loveland, CO

A laminectomy specifically means removal of the entire lamina, which is a portion of the spine allowing access to the spinal cord and/or nerve roots. A more accurate term would be a laminotomy, which involves partial removal of the bone. This is the procedure most typically performed for a disc herniation. Rarely is the entire removal of the lamina, or laminectomy, performed.

Dr. Sean Salehi
Chicago, IL

A laminectomy involves removing the bone overlying the spinal canal.

Dr. John S. Shiau
Staten Island, NY

A laminectomy means removing the lamina. Ectomy means removal of, and lamina is basically the roof of the spine, so laminectomy means removing the roof of the spine.

Dr. Dennis G. Crandall
Mesa, AZ

Laminectomy means removing the lamina, or the “roof” of the spinal canal. This gives the nerves the room they need to function fully, providing strength and sensation to the legs.

Dr. Sebastian Lattuga
Rockville Centre, NY

A laminectomy is a procedure were the surgeon removes a small amount of bone and tissue that is compressing the nerves.

Dr. Ezriel E. Kornel
White Plains, NY

A laminectomy is, in the strictest sense, the removal of the lamina or roof of the spine. The two lamina come together on either side to form the spinous process, which is that bone that sticks up into the back that one can feel when one runs a hand along the spine. It is also more generically used as any term meaning a procedure that involves removing even part of that bone in order to enter the spine.

Dr. Sylvain Palmer
Mission Viejo, CA

Laminectomy is removal of the back side of the spinal canal under which lie the nerve tissues. This provides access to the nerves and the discs for specific treatment.

Dr. Kambiz Hannani
Los Angeles, CA

The lamina is the bony covering of the spinal canal. When the canal narrows, your surgeon can remove a small amount of bone through very small incisions to open up the spinal canal. This surgical procedure is called a laminectomy. A laminectomy can significantly help with leg pain and, at times, back pain. Laminectomy alone, however, can also cause other problems, such as spinal instability. Your surgeon will determine if a fusion is necessary to try to avoid this instability.

Dr. Jorge E. Isaza
Baton Rouge, LA

A laminectomy involves removing the posterior part of a vertebral segment or backbone, which is called the lamina. A laminectomy is performed to provide access to the spinal canal so that bone spurs, tumors, infections, and hematomas can be removed or to treat other conditions that require posterior access. It is also done, for example, to decompress a nerve at a particular level in the spine.

Dr. Robert S. Pashman
Los Angeles, CA

A laminectomy is the removal of a small portion of the vertebra, (lamina) around the affected area. This is done to relieve pressure on the nerve roots.

Dr. Eung-Jun Cha
Bedford, IN

Excision of posterior arch, usually to remove a lesion, herniated disc or bone spur.

Dr. Andrew Glass
Someras Pt., NJ

The bony arches behind the sac of nerves in the lower back are called laminae. An operation where one or more arches or pieces of arches is removed is referred to as a laminectomy. A laminectomy may be performed to simply relieve nerve pressure or to provide access to another part of the spine. In some instances, the laminectomy is the entire operation. In other instances, the laminectomy is the first of several stages of the operation.

Dr. Donald D. Dietze Jr.
Covington, LA

Laminectomy is used to refer to a category of surgeries where the back part of the bony spinal canal is partially or completely removed to expose and decompress the central spinal nerve sac. The incision is made on the back and is called a posterior approach.

It is important that you discuss the potential risks, complications and benefits of spinal surgery with your doctor prior to receiving treatment, and that you rely on your doctor's judgment. Only your doctor can determine whether you are a suitable candidate for this treatment.
