Spinal dysraphism.

Spinal dysraphism (SD) is characterized by maldevelopment of neural tube, notochord, mesoderm and cutaneous ectoderm. Incidence of SD is 2-4/1000 live births. One hundred and nineteen patients operated from January 1991-June 1996 at Department of Neurosurgery, All India Institute of Medical Sciences, were studied. Only 21 patients (17.6%) presented when they were less than one year old and 17 patients came in adult age group (> 16 years). Lumbar and lumbosacral region was the commonly involved site in 81 patients (74.7%). Weakness of lower limbs (74%), difficulty in walking (54%), muscle atrophy (41.2%) were the commonest indicators of motor system involvement. Loss of sensation, trophic ulcer, backache were seen in 45, 14, 10 patients respectively. Cutaneous lipoma (26%), hypertrichiosis (20%), dermal sinus (13.4%), midline dimples (7%) were the important cutaneous markers. Foot and limb deformity was seen in 25% cases. Tethering of cord, syringomyelia & split cord malformation were the most common radiological findings. Only 10% of our patients had hydrocephalus that required shunt. Out on 119 cases operated, 43 improved, Twenty had sensory improvement and 18 showed motor improvement. Fifteen patients regained continence. Twelve patients were lost to follow-up. Sixty-seven patients had no change in neurological status, post-operatively. Six cases deteriorated in terms of motor or sensory deficit and one patient lost continence. CSF leak (8%) and wound infection (6%) were the common complications. Six patients required second surgery as T.P. Shunt (4), rotation flap (1), reexploration and duraplasty (1).[1]
