Results 28 children received effctive curative effect after the surgical treatment in 43children with tethered cord syn-drome,the total effective rate was 65. 12%. Cox medol showed that tight filum terminale(P<0. 05), operation methods (P<0. 05)and the duration of the disease(P<0. 05)were independent risk factors of surgical treatment for children’s tethered cord syndrome.
