Project Title: Pre-operational and post-operational motor stimulated potential, electrophysiological conduction studies in patients with tethered cord syndrome, ne- urological examination and comparison of lumbosacral MRI investigations. Abstract: Tethered cord syndrome (TCS) is a clinical picture occurring together with progressive neurological symptoms and ndings such as movement, sensory im- pairments, and incontinence in lower extremities depending on mechanical regression of the spinal cord, often accompanied with muscle and skeletal system malformations. [1, 8] Diseases such as terminal myelocystocele and sti lumterminale occurring as a result of canalization impairment of the caudal bud or myelomeningocele, lipomye- lomeningosel, dermal sinus tractus, split spinal cord malformation (SCM) occurring as a result of neurulation impairment in embryologic period in this syndrome that may be develop by natal or acquired reasons forms the reasons of natal (primary) (TCS). Cohesions that may be formed following an experienced myelomeningocele, the surgeries such as spinal tumor or after spinal trauma may also a reason of acquired (secondary) tethered cord syndrome. TCS is diagnosed by clinicaly. Many methods are helpful in TCS diagnosis such as radiological studies, somatosensory evoked po- tentials (SEP) and urodynamics study. The most important radiological diagnosis tool used for determining the TCS is lumbosacral magnetic resonance imaging (MRI) [4, 5, 7, 29, 53, 64] In this study, the aim is to compare the results of lumbosacral MRI and electrophy- siological Motor evoked potentials (MEP) and conduction study as preoperational and post-operational clinical imaging in 20 patients over 18 years old diagnosed with de nitive TCS. We aimed at contributing to the literature and our university with the results to be obtained in the light of abovementioned information in this study due the fact that there is no study carried out previously about this subject.
