36
Q

Laminectomy

A

The removal of the lamina, frequently done to relieve pressure on the nerves (spinal stenosis).

37
Q

Laminotomy

A

A removal of a small portion of the lamina, frequently done to remove a portion of the disc.

38
Q

Lordosis

A

The normal backward curve which occurs in the cervical and lumbar region.

A

The lowest portion of the spine. There are five lumbar vertebrae in the low back.

40
Q

Microdiscectomy

A

The removal of a ruptured disc through a small incision with the aid of a microscope.

41
Q

Myelography

A

The injection of contrast material into the subarachnoid space. This is often followed by an x-ray or CT scan.
