If MRI shows a prolapsed disc at L4 with cauda equina syndrome, what is the definitive management?

• A. Surgical decompression
• B. High-dose steroids
• C. Spinal fusion
• D. Physical therapy

Answer: (A)

Cauda equina syndrome from an acute disc herniation is a surgical emergency. The most effective and definitive treatment is urgent surgical decompression to relieve pressure on the cauda equina and nerve roots. Prompt decompression aims to restore blood flow and neural function, improving the chances of recovery of bladder, bowel, and leg function. Time matters: outcomes are best when decompression is performed as soon as possible, ideally within 24 hours of symptom onset. High-dose steroids do not provide proven benefit in this setting and carry risks, so they are not the primary treatment. Spinal fusion is not indicated for a single-level prolapsed disc causing CES unless there is another reason for instability or deformity. Physical therapy alone cannot rapidly address the acute compression causing CES. Thus, the definitive management is immediate surgical decompression.
