Spinal Discectomy

Lumbar discectomy is a surgery to remove a herniated or degenerative disc in the lower spine. The incision is made posterior, through the back muscles, to remove the disc pressing on the nerve. Discectomy may be recommended if physical therapy or medication fail to relieve leg or back pain or if you have signs of nerve damage, such as weakness or loss of feeling in your legs. The surgery can be performed in an open or minimally invasive technique.

Treatments

Spinal Discectomy
Open discectomy is usually performed under general anesthesia (the patient is unconscious) and typically requires a one-day hospital stay. It is performed while the patient is lying face down or in a kneeling position. During the procedure, the surgeon will make an approximately one-inch incision in the skin over the affected area of the spine. Muscle tissue is removed from the bone (lamina) above and below the affected disc and retractors hold the muscle and skin away from the surgical site so the surgeon has a clear view of the vertebrae and disc. In some cases bone and ligaments may have to be removed for the surgeon to be able to visualize and then gain access to the disc without damaging the nerve tissue. This is called a laminectomy or laminotomy depending on how much bone is removed. Once the surgeon can visualize the lamina of the vertebrae, disc and other surrounding structures, he or she will remove the section of the disc that is protruding from the disc wall and any other disc fragments that may have been expelled from the disc. This is often done under magnification. No material is used to replace the disc tissue that is removed. The incision is then closed with sutures and the patient is taken to a recovery room. View
