These patients usually present posttraumatically with the triad of saddle anesthesia, bowel or bladder dysfunction, and lower extremity weakness. Significant morbidity can result from delayed diagnosis and treatment; therefore, the emergency physician should remain aware of this potential orthopedic pitfall.
