Showing Laminectomy

Traveling From Canada

Laminectomy is a spine operation to remove the portion of the vertebral bone called the lamina. The lamina is a posterior arch of the vertebral bone laying between the spinous process. Indications for laminectomy include (i) treatment of severe spinal stenosis by relieving pressure on the spinal cord or nerve roots, (ii) access to a tumor or other mass lying in or around the spinal cord, or (iii) a step in tailoring the contour of the vertebral column to correct a spinal deformity such as kyphosis. The actual bone removal may be carried out with a variety of surgical tools, including drills, rongeurs, and laser.
