Objective/Background: The standard treatment for tethered cord syndrome (operative vs nonoperative management) that presents in adulthood remains controversial. A comparative study. of tethered cord syndrome in adulthood is needed. Design: A retrospective chart-based analysis. Methods: Patients admitted to Gulhane Military Medical Academy Department of Neurosurgery for management of caudal spinal cord tethering from June 1999 through December 2006 (N = 22). Results: Conus level was normal in 1 patient with split cord malformation and dermal sinus. Tight terminal filum was found in 21 patients, including postrepair myelomeningocele tethered cord in 4, lipomyelomeningocele/meningocele in 8, split cord malformation in 3, dermal sinus in 7, and syringomyelia in 3. The most common complaints were back pain (15 patients, 68.1%), bladder dysfunction (8, 36.3%), fecal incontinence (2, 9.09%), and leg pain (7,31.8%). One patient had hydrocephalus (4.5%). Ten of 22 patients underwent surgery; 8 of 10 patients had detethering; and 12 patients refused surgery. Postoperative cerebrospinal fluid leakage requiring reinforcement sutures occurred in 1 patient. There were no infectious complications. Neurologic status and outcomes were compared with preoperative findings. Conclusions: Some patients refuse surgery despite severe neurologic disturbances. Neurosurgeons should fully explain the risks and benefits of surgery for tethered cord to the patient and family. A much larger and prospective randomized series is needed to determine the effects of operative vs nonoperative management of tethered cord syndrome in adulthood.
