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.


A review of recent (since 1991) and prior (since 1941) investigations regarding CES and TRI (TNSs) was conducted.


Recent publications fail to recognize significant prior information regarding CES and TRI (TNSs).


Cauda equina syndrome is, in all probability, explainable. Further investigation to pinpoint the etiology of TRI (TNSs) is needed.
