A spinal disc herniation occurs when a disc—the soft cushion between two vertebrae—pushes outward beyond the normal boundaries of a healthy disc. Medical professionals use several terms to describe the extent of a spinal disc herniation seen on an MRI examination, including disc protrusion, disc extrusion, and disc sequestration.

When the foramen close in, the nerve roots passing Foraminal disc protrusions are an important entity to recognize for a number of reasons, these include: they are relatively easy to overlook as they do not impinge upon the spinal canal they do not narrow the subarticular recess , but compresses the exiting nerve root only, thus clinically mimicking a posterolateral disc from the level above. Disc Herniation—Foraminal Clinical Presentation. The patient is a 65-year-old male with a 2-year history of progressive right thigh pain radiating Imaging Presentation. Magnetic resonance (MR) imaging of the lumbar spine reveals a large herniated disc extending into Discussion. Foraminal or Results: The preprocedural and postprocedural mean VAS scores for radicular pain in foraminal disc herniation were 67.11 ± 4.28 and 34.78 ± 3.64, respectively. However, the preprocedural and postprocedural mean VAS scores in paramedian disc herniation were 62.16 ± 6.65 and 19.07 ± 4.50, respectively. This fenestration exposes the foraminal root compressed by the herniated disc, which can be easily removed.

Foraminal herniation

Right foraminal narrowing, also called foraminal stenosis, occurs when an anatomical abnormality causes a foramen on the right side of a vertebra to become narrower. Foramina are the open passageways on either side of each vertebra that allow spinal nerves to exit the spinal cord and send sensory and motor signals throughout the rest of the body. Degenerative spine conditions like a herniated disc, a bulging disc, bone spurs or spondylolisthesis are the primary reason that the foramina Foraminal disc protrusions are an important entity to recognize for a number of reasons, these include: they are relatively easy to overlook as they do not impinge upon the spinal canal they do not narrow the subarticular recess, but compresses the exiting nerve root only, thus clinically mimicking a posterolateral disc from the level above. Foraminal stenosis may be caused by a herniated disc, bulging disc, bone spur or facet joint hypertrophy. A herniated disc does not cause pain on its own.

Foraminal disc herniations cause fierce leg pain and are often intractable to conservative treatment. Selection of the surgical approach is often a matter of debate.

The L4 nerve root is most commonly involved. Foraminal disc herniations tend to occur in older patients, often with little evidence of disc degeneration. Herniated discs can bulge into the foraminal opening, compressing the nerve root against the wall of the neuroforamen. This is sometimes called nerve compression, nerve impingement or nerve constriction. This condition is very commonly diagnosed, but is actually often an incorrect symptomatic assessment.

Selection of the surgical approach is often a matter of debate. A tear can occur within the annulus fibrosus. The material of the nucleus pulposus can track through this tear and into the intervertebral or vertebral foramen to Initial symptoms of pain and paresthesia tend to be markedly more severe with disc herniation.

Brain herniation frequently presents with abnormal posturing, a characteristic positioning of the limbs indicative of severe brain damage. These patients have a lowered level of consciousness, with Glasgow Coma Scores of three to five.
