The investigators hypothesize that surgical release of the filum terminale (strand of fibrous tissue at the end of the spinal cord) is a more efficacious treatment option for symptomatic relief than medical management in subjects with Occult Tethered Cord Syndrome (OTCS) and that the risks do not outweigh the benefit profile.
This is a phase II pilot randomized-controlled, single-site trial to determine if surgical untethering of the filum terminale is more effective, preliminarily, than medical management as a treatment option for OTCS. Subjects will be randomized to one of two arms: surgical untethering or medical management only. Symptom improvement and adverse events will be assessed and recorded for 1 year from initiation of treatment. After a minimum of 1 year, subjects who were randomized to the medical management arm may cross over to the surgical arm if the PI deems it is in the subject's best interest to…
