By Michael Perry, M.D. Foraminal narrowing, or foraminal stenosis, is a condition of the spine that can cause pain and other symptoms resulting from spinal nerve root compression. At every level of the spine, a pair of nerve roots runs through the spinal column via small openings called foramina (singular: foramen).
Lesser sciatic foramen, an opening between the pelvis and the posterior thigh. Obturator foramen, the hole created by the ischium and pubis bones of the pelvis. Sacral foramina, which perforate the vertebral canal from the Sacrum (sacral bone), and through which the sacral nerves pass.
