A diskectomy (also called open diskectomy) is the surgical removal of herniated disc material pressing on a nerve root or the spinal cord.

A microdiskectomy is a minimally invasive version of a diskectomy, which is done with the use of a microscope and small incisions.

The procedure involves removing the central portion of an intervertebral disc, the nucleus pulposus, which causes pain by stressing the spinal cord or radiating nerves.
