Abstract
Context: Tethered cord syndrome is a progressive condition usually diagnosed early in life, and leads to a diversity of manifestations including neurologic, urologic, and orthopedic dysfunction. Findings: We report two cases of tethered cord syndrome associated with a unilaterally absent sural sensory response on nerve conduction studies while other causes of this finding being excluded. Conclusion/clinical relevance: We believe that this finding is caused by a selective injury of sensory fibers at the level or distal to the dorsal root ganglia. © The Academy of Spinal Cord Injury Professionals, Inc. 2020.
