Laminectomy is one of the most common back surgeries. During a laminectomy, a surgeon removes the rear portion of one or more spinal bones (vertebrae). Bone spurs and ligaments that are pressing on nerves may be removed at the same time. The surgeon will make an incision in the skin of your back over the affected area. The muscles and soft tissues around the spine will be pulled to the side, exposing the spine. The surgeon will then cut away bone, bone spurs, and ligaments that are compressing nerves. This is referred to as decompression. The surgeon may remove a small part or a large portion of several spinal bones, depending on your reason for the operation.
Similarly, a Discectomy is a surgical procedure to remove the damaged portion of a herniated disc in your spine. A herniated disc can irritate or compress nearby nerves. Discectomy is most effective for treating pain that radiates down your arms or legs.
The procedure is less helpful for treating actual back pain or neck pain. Most people who have back pain or neck pain find relief with more-conservative treatments, such as physical therapy.
Your doctor may suggest discectomy if conservative, nonsurgical treatments haven’t worked or if your symptoms worsen.
