In anatomy, a foramen (/fəˈreɪmən/;[1][2] pl. foramina, /fəˈræmənə/) is any opening. Foramina inside the body of humans and other animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another.

Examples [edit]
Skull [edit]
Main article: Foramina of the skull
The skulls of vertebrates, including the human skull, have numerous foramina through which nerves, arteries, veins and other structures pass.
Spine [edit]
Main article: Intervertebral foramina
Within the vertebral column (spine) of vertebrates, including the human spine, each bone has an opening at both its top and bottom to allow nerves, arteries, veins, etc. to pass through.
Other [edit]
- Apical foramen, the hole at the tip of the root of a tooth
- Foramen ovale (heart), a hole between the venous and arterial sides of the fetal heart
- Foramen transversarium, one of a pair of openings in each cervical vertebra, in which the vertebral artery travels
- Greater sciatic foramen, a major foramen of the pelvis
- Interventricular foramina, channels connecting ventricles in the brain
- 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
- Vertebral foramen, the foramen formed by the anterior segment (the body), and the posterior part, the vertebral arch.

Electronic address: jlobo.antunes@mail.telepac.pt.AbstractNarrowing of the spinal canal or foramina is a common finding in spine imaging of the elderly. Only when symptoms of neurogenic claudication and/or cervical myelopathy are present is a spinal stenosis diagnosis made, either of the lumbar spine, cervical spine or both (only very rarely is the thoracic spine involved). Epidemiological data suggest an incidence of 1 case per 100 000 for cervical spine stenosis and 5 cases per 100 000 for lumbar spine stenosis. Cervical myelopathy in patients over 50 years of age is most commonly due to cervical spine stenosis. Symptomatic spinal narrowing can be congenital, or, more frequently, acquired. The latter may be the result of systemic illneses, namely endocrinopathies (such as Cushing disease or acromegaly), calcium metabolism disorders (including hyporarthyroidism and Paget disease), inflammatory diseases (such as rheumathoid arthritis) and infectious diseases. Physical examination is more often abnormal in cervical spondylotic myeloptahy whereas in lumbar spinal stenosis it is typically normal. Therefore spinal stenosis diagnosis relies on the clinical picture corresponding to conspicuous causative changes identified by imaging techniques, most importantly CT and MRI. Other ancillary diagnostic tests are more likely to be yielding for establishing a differential diagnosis, namely vascular claudication. Most patients have a progressive presentation and are offered non operative management as first treatment strategy. Surgery is indicated for progressive intolerable symptoms or, more rarely, for the neurologically catastrophic initial presentations. Surgical strategy consists mainly of decompression (depending on the anatomical level and type of narrowing: laminectomy, foraminotomy, discectomy, corporectomy) with additional instrumentation should spinal stability and sagittal balance be at risk. For cervical spine stenosis the main objective of surgery is to halt disease progression. There is class 1b evidence that surgery is of benefit for lumbar stenosis at least in the short term.
