Filum terminale transection in pediatric tethered cord syndrome: a single center, population-based, cohort study of 95 cases.

Neurological improvement or halted deterioration was seen in the majority of symptomatic cases. Asymptomatic patients did not experience any severe complications. Filum transection should be offered to symptomatic and asymptomatic patients upon diagnosis of fatty filum, thickened FT, or low-lying conus.
