Background and Importance: Idiopathic Spin. Cord Herniation is An Uncommon Condition Located Predominantly in the Thorac. Spine and Often Assoc. with A Remote Hist. of A Major Traum. Inj.. ISCH Has An Incompletely Described Presentation and Unknown Etiology. There is No Consensus on the Treatm. Algorith. and Surg. Tech., and There Are Few Data on Clin. Outcomes. Clin. Presentation: in This Case Ser. and Tech. Report, We Describe the Atypical Myelopathy Presentation, Remote Hist. of Traum. Inj., Radiographic Progression, Treatm., and Outcomes of 5 Patients Treated at Washington Univ. for Symptomatic ISCH. A Video Showing Surg. Repair is Presented. in Contrast to Class. Compressive Myelopathy Symptomatology, ISCH Patients Presented with An Atypical Myelopathy, Characterized by Asymmetric Motor and Sensory Deficits and Early-onset Urinary Incontinence. Clin. Deterioration Correlated with Progressive Spin. Cord Displacement and Herniation Observed on Yearly Spin. Imaging in A Patient Imaged Serially because of Multiple Sclerosis. Finally, Compared with Compressive Myelopathy in the Thorac. Spine, Surg. Treatm. of ISCH Led to Rapid Improvement Despite A Long Duration of Symptoms. Conclusion: Symptomatic ISCH Presents with Atypical Myelopathy and Slow Temporal Progression and Can Be Successfully Managed with Surg. Repair.
