In minimally invasive lumbar microdecompression surgery, your surgeon will make one or more small incisions to insert a tubular retractor to create a tunnel through the muscle and soft tissues to get the area of the spine that is the problem. The tubular retractor stays in place during the entire procedure. The Tubular retractors spare cutting through muscles and soft tissues and minimize damage.
Using these retractors, your surgeon can gently and progressively dilate and separate muscles and soft tissue to get to the operative field. Specialized instruments and microscopic visualization enable the surgeon to perform the operation through the tube.
During this type of surgery, your surgeon can remove bone or tissue and enlarge the passageway where the nerves are compressed and causing pain.
