Purpose
The term “tethered cord syndrome” (TCS) illustrates, according to the literature, both a separate diagnosis, as well as a combination of symptoms in the context of dysraphic conditions. The common denominator is the increased tension and abnormal stretching of the spinal cord, caused by tissue attachments that limit its movement in the spinal canal. In light of the fact that no real data exists regarding the management of these patients, the purpose of this single institutional study is to underscore management strategies and discuss the results, pitfalls, and the treatment of pediatric patients with tethered cord syndrome.
Methods and results
The clinical outcome in 20 pediatric patients was studied retrospectively. Ten children with closed spinal dysraphism, nine with tethering after postpartum myelomeningocele repair, and one child with an infected open dermal sinus were included. A total of 22 detethering procedures were performed. The most common symptoms prior to surgery were muscle weakness and urinary dysfunction, followed by foot deformities and pain. Of all symptoms, pain responded most favorably to surgical treatment. There was improvement in 11 out of 15 patients with preoperative motor deficits, while that was the case in 11 out of 16 patients with urinary dysfunction.
Conclusions
In view of the lack of evidence regarding the treatment of children with tethered cord syndrome, the best way to aim for a favorable outcome is correct indication for surgical intervention, combined with the implementation of technical advancements, such as intraoperative neurophysiological monitoring and ultrasound.
