Stenosis is a degenerative condition in which the spinal canal narrows. This compresses the spinal cord and presses on nerves. Stenosis most often occurs in elderly patients. Surgery, known as a laminectomy, is required to relieve the pressure by removing a portion of the spinal canal cap and providing the spinal cord with a synthetic protective cover in its place. A 3-D model can assist the orthopaedic surgeon in pinpointing the exact point of pressure and determining the amount of substance that needs removed. This invasive surgery, as with so many others, is better reduced to only the minimum amount of structure as absolutely necessary to relieve the pain. By utilizing a 3-D model to know exactly how much removal is necessary before going into surgery, tens of thousands of dollars can be saved by shortening time in surgery, as well as the recovery period.
