Foraminotomy
Encyclopedia
Foraminotomy is a medical operation used to relieve pressure on nerve
s that are being compressed by the intervertebral foramina
, the passages through the bones of the vertebrae of the spine
that pass nerve bundles to the body from the spinal cord
.
A foraminotomy is performed to relieve the symptoms of nerve root compression in cases where the foramen is being compressed by bone, disc, scar tissue, or excessive ligament development and results in a pinched nerve.
The procedure is often performed as a minimally invasive procedure
in which an incision is made in the back of the neck, the muscle peeled away to reveal the bone underneath, and a small hole cut into the vertebra itself. Through this hole, using an arthroscope, the foramen can be visualized, and the impinging bone or disk material removed.
Nerve
A peripheral nerve, or simply nerve, is an enclosed, cable-like bundle of peripheral axons . A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons. Nerves are found only in the peripheral nervous system...

Intervertebral foramina
When the spinal vertebrae are articulated with each other the bodies form a strong pillar for the support of the head and trunk, and the vertebral foramina constitute a canal for the protection of the medulla spinalis...

Vertebral column
In human anatomy, the vertebral column is a column usually consisting of 24 articulating vertebrae, and 9 fused vertebrae in the sacrum and the coccyx. It is situated in the dorsal aspect of the torso, separated by intervertebral discs...

Laparoscopic surgery
Laparoscopic surgery, also called minimally invasive surgery , bandaid surgery, or keyhole surgery, is a modern surgical technique in which operations in the abdomen are performed through small incisions as opposed to the larger incisions needed in laparotomy.Keyhole surgery makes use of images...
