Regarding the management of cauda equina syndrome secondary to a large acute L3-L4 disc herniation, which of the following statements is most accurate regarding timing of surgical decompression?

• A Emergent decompression within 48 hours of symptom onset is recommended ✓
• B Surgery can be safely delayed up to 2 weeks with equivalent outcomes
• C Surgery is indicated only if conservative management fails after 6 weeks
• D Urgent surgery is indicated only in the presence of complete paraplegia

Explanation

Cauda equina syndrome is a surgical emergency. It presents with saddle anesthesia, bladder/bowel dysfunction, and lower motor neuron signs in the legs. Current guidelines recommend emergent surgical decompression within 48 hours of symptom onset to maximize chances of neurological recovery, particularly for bladder function. Delay beyond 48 hours is associated with worse outcomes. It is distinct from conus medullaris syndrome and requires urgent MRI confirmation and decompression.
