Hemilaminectomy

A hemilaminectomy is a procedure used to decompress pinched nerve roots by removing a single lamina bone.


In order to end nerve root irritation, a hemilaminectomy can be performed. This procedure involves the surgical removal of a lamina: a portion of bone that is found on both sides of a vertebra along the back of the spine. Unlike a laminectomy, which removes the lamina on both sides of a vertebra, a hemilaminectomy removes only one lamina bone. Removing only one lamina helps the spine to retain more stability and allows surgeons to perform the procedure using a much smaller incision.

Who should receive a hemilaminectomy?

There are many conditions that may cause a lamina to compress nerve roots, including osteoarthritis, degenerative disc disease, spinal stenosis, or a herniated or bulging disc. If nerves are being compressed, you may experience decreased motor skills and chronic throbbing or shooting back pain, especially when sitting. If patients have unsuccessfully undergone conservative methods to treat the pain, such as physical therapy, they may be a candidate for a hemilaminectomy.

How it Works

Renova’s physicians can use AccuCision® Spine to quickly and safely perform a hemilaminectomy. A typical hemilaminectomy requires an incision of up to 3 inches. However, AccuCision allows the surgeon to create an incision of less than 5mm. Through this incision, the surgeon can insert an instrument with a 2mm tip. This instrument is used to remove the targeted lamina. With AccuCision, our doctors are able to perform this procedure with minimal instrument passes and minimal tissue disruption.
