Relation Between Disc Herniation & Compressed Nerve Root Levels

The video explains why a posterolateral disc herniation at the L4-L5 level compresses the L5 nerve root instead of the L4 nerve root. It covers the anatomy of the vertebral canal, intervertebral regions, and nerve root exit points. The L4 nerve root exits above the herniation level, while the L5 nerve root descends through the L4-L5 space, making it susceptible to compression. The video generalizes this concept to other spinal levels, emphasizing the importance of understanding cauda equina nerve roots within the vertebral canal.
