What is subligamentous herniation of L4-L5 disc. Bulging of L5-S1 disc.

Not Medical Advice: Your backbone/spine is made up of 26 bones called vertebrae. In between those vertebrae are soft discs filled with a jelly-like substance. A subligametous herniated disc is a disc that ruptures. The jelly-like center of the disc leaks, irritating the nearby nerves.

Disc herniation is a common injury that can affect any part of the spine but most disc herniations happen at the two lowest discs, L4-L5 and L5-S1.

In L4/ L5 disc herniations, the L5 nerve root is usually more compressed than the L4 root. For the L4 root to be affected, disc herniation usually occurs more laterally out in the direct area of the neural foramen.

A bulging disc goes outside the area it should normally occupy. It is typically the tough outer layer of cartilage and is common to see on MRIs of people in almost every age group and is considered part of the normal aging process of the disc.

L4-L5 and L5-S1 Disc Herniation Symptoms:|

  • At the L4-L5 level, L5 nerve impingement from a herniated disc can cause weakness in extending the big toe and potentially in the ankle. Pain and numbness can be felt on top of the foot. Pain may also radiate into the buttock.
  • At the L5-S1 level, S1 nerve impingement from a herniated disc causes loss of the ankle reflex or weakness in ankle push off. Pain and numbness can extend down to the sole or outside of the foot.
