foraminotomy
Pronunciation: for-ah-min-OT-uh-mee
Surgical enlargement of the neural foramen to decompress exiting nerve roots.
Full Definition
Foraminotomy is a surgical decompression procedure that involves enlarging the neural foramen (the opening through which spinal nerve roots exit the spinal canal) to relieve nerve root compression. This procedure typically involves removal of bone, ligament, and soft tissue that may be compressing the nerve root as it exits the spine. Foraminotomy can be performed through various approaches including posterior, lateral, or endoscopic techniques. The goal is to provide adequate space for the nerve root while preserving as much normal anatomy as possible, particularly the facet joints that provide spinal stability.
