The use of an endoscope enables minimum invasion for the treatment of discal hernia, spinal stenosis and chronic discopathy. A minimal incision (12-14 mm) enables introduction of a work cannula guided by CAT scan/scopy and neuronavigation systems to the area of therapeutic interest. Among the advantages of the endoscopic system for treatment of discal hernia is the avoidance of the spinal canal, thus preventing the appearance of post-surgical fibrosis. As there is less damage to tissues, especially muscles, the postoperative period is less painful and post-surgical recovery much faster.
