Cauda Equina Syndrome; Roadside to Resus

Cauda Equina Syndrome represents a critical spinal emergency requiring rapid recognition to prevent irreversible neurological damage, including bowel, bladder, and sexual dysfunction. While often caused by large central disc herniations, clinicians must remain vigilant for secondary etiologies like malignancy, infection, or hematoma. Diagnosis relies on identifying red flags—such as saddle sensory changes, urinary retention, or progressive bilateral leg weakness—within the context of back or radicular pain. Although MRI serves as the diagnostic gold standard, achieving the recommended four-hour turnaround remains a significant logistical hurdle in emergency departments. Management focuses on minimizing secondary nerve injury through prompt surgical decompression, typically via laminectomy or discectomy. Because no single clinical sign is pathognomonic, maintaining a high index of suspicion and utilizing tools like post-void residual bladder scanning are essential for timely intervention and improved patient outcomes.
