Over 80% of the adult population will experience back pain at some phase of life. One of the most distressing sources of pain, disk herniation, can create a shooting or burning sensation and/or paresthesias (abnormal sensations, such as tingling) in the buttock, upper and lower leg. Which levels of the spine are the MOST susceptible to herniation?

Question

Quizplus · Accepted Answer

Most disk herniations occur between the two lowest lumbar vertebra (L4 and L5) and between the lumbar-sacral junction (L5 and S1).Not all disk herniations are symptomatic, but the most severe cases can cause weakness in the legs - often experienced as tripping or foot drop -- and a sudden onset of incontinence of bowel or bladder. These later symptoms should be reported to a physician immediately as they may represent central cord compression and create permanent nerve damage.
