This is a minimally invasive procedure that relieves nerve root compression by widening the intervertebral foramen, the space through which the spinal nerve exits from the spinal cord. This procedure also allows the surgeon to remove a herniated disc fragment that is pressing on the nerve. The procedure is done microsurgically.
A small incision is made at the back of the neck. Fat and muscle is pushed aside until the spinal column is exposed. The intervertebral foramen is enlarged with microsurgical instruments and any herniated disc fragments are removed.
