BACKGROUND AND OBJECTIVES: To evaluate the etiologies of cauda equina syndrome (CES) and transient radicular irritation (TRI) or transient neurologic symptoms (TNSs) following hyperbaric spinal anesthesia. METHODS: A review of recent (since 1991) and prior (since 1941) investigations regarding CES and TRI (TNSs) was conducted. RESULTS: Recent publications fail to recognize significant prior information regarding CES and TRI (TNSs). CONCLUSIONS: Cauda equina syndrome is, in all probability, explainable. Further investigation to pinpoint the etiology of TRI (TNSs) is needed.
