Defined as a minimally invasive surgery, endoscopic microdiscectomy requires a small incision, usually no larger than 1 cm, and x-rays to gain access to the lumbar spine.
Under x-ray guidance, a series of muscle dilators are used to stretch soft tissue, instead of cutting muscles, and create a path for the endoscope. Special instruments can also be used to shave down arthritic bone that may also be compressing a nerve. Once placed, the endoscope allows the physician to use direct visualization of the disc, nerve, and other structures and to safely remove problematic disc, freeing up the nerves.

Usually done under monitored anesthesia care, meaning you’re awake and responsive, but comfortable throughout the
procedure.
Unlike traditional open surgery, in which muscles, ligaments, and even and bones might be severed to reach the specified area; endoscopic microdiscectomy uses an endoscope, or small camera, to magnify the area where the microdiscectomy will be performed. Through the use of this technique only a small portion of the herniated disc that is compressing the spinal nerve needs to be removed.
