Overview
A minimally invasive lumbar laminectomy (also called tubular laminectomy) is a minimally invasive procedure which is performed to address nerve compression caused by spinal stenosis (see lumbar spinal stenosis). During the procedure, a small incision is made just off the midline of the spine. Using a microscope, a dissection is carried down through a small amount of muscle to the lamina, the portion of bone which sits at the back of the spinal canal. Additionally, a small tube is used to gently retract much of the muscle out of the field, protecting the integrity of the muscle tissue. Once exposed, a high-speed burr is used to shave through a portion of the lamina which effectively frees the nerves from pressure. This typically takes 45-60 minutes from start to finish, with most patients returning home the same day.
Post operative expectations
Many patients feel rapid relief following a lumbar laminectomy. Activity is typically restricted for a short time after surgery, with most patients returning to work within two to six weeks. By three months, most patients feel excellent and are ready to return to full, unrestricted activities.
