What is the most common cause of Cauda Equina syndrome?

• A. Trauma
• B. Disk herniation
• C. Spinal stenosis
• D. Neoplasm

Answer: (B)

Cauda Equina syndrome is primarily caused by the compression of the cauda equina nerves, which is most commonly due to disk herniation. When a herniated intervertebral disk occurs, especially in the lumbar region, it can protrude and exert pressure on these nerves. This can lead to a variety of neurological symptoms such as low back pain, sciatica, saddle anesthesia, and motor weakness, among others.

While trauma, spinal stenosis, and neoplasms can also cause cauda equina syndrome, herniated disks are considerably more frequent in clinical practice, making them the leading cause. The mechanical pressure that results from a herniated disk is a well-understood mechanism explaining the onset of symptoms associated with this syndrome. Understanding this relationship is crucial for timely diagnosis and intervention to prevent permanent neurological damage.
