This is accomplished by applying open surgical techniques through a tubular retractor under microscopic visualization. For the first time, a laminotomy, medial facetectomy, foraminotomy, nerve root retraction and discectomy can be performed through the reliability of conventional open surgery with the advantages of a minimally invasive technique. With proper patient selection, the technique for the Metrx™ system allows for adequate nerve root decompression and provides the numerous benefit
