Minimally invasive spine surgery was developed to treat spine problems with less injury to the muscles and other normal structures in the spine. Other advantages include smaller incisions, less bleeding, and shorter stays in the hospital.
Laminectomy/Discectomy is an ambulatory surgery meaning you will leave the hospital the same day as the surgery.
This procedure is necessary when a herniated disc or bone spurs in the lower back pinch a nerve, thereby causing severe leg pain, numbness, or weakness. To surgically relieve these symptoms, the disc or bone spurs are removed. This procedure is called a “Discectomy” for the disc removal, or “Laminectomy” for the bone removal.
For the surgery, the patient is positioned face-down and a small incision (sometimes less than one inch.) is made over the location of the herniated disc. The surgeon inserts the retractor and removes a small amount of the lamina bone. This provides the surgeon with a view of the spinal nerve and the disc. The surgeon carefully retracts the nerve, removes the damaged disc, and replaces it with bone graft material.
This minimally invasive technique can also be used for herniated discs in the neck. The procedure is done through the back of the neck and called an MIS posterior cervical discectomy.
