Tethered cord syndrome is related to the tendency for the spinal cord to adhere to the myelomeningocele repair and prevent the normal movement of the cord during growth. Symptoms can include pain, sensory changes, spasticity, and progressive scoliosis. Surgical release is performed to attempt to return to previous level of function and prevent further loss. Similar symptoms caused by other intraspinal pathologies (e.g., mass lesions of the cord, cord cavitation and narrowing, adhesions, dural bands). Hydrosyringomyelia (the presence of longitudinally orientated CSF-filled cavities within the spinal cord) is caused by hydrocephalus. Hydrosyringomyelia results in entry of cerebral spinal fluid (CSF) into the central canal of the spinal cord, causing dilatation and pressure (Iskandar, 2000).
