There’s a lot of issues this doesn’t fix, like a lot (90%+) of spina bifida cases require shunts to drain cranial spinal fluid. Your spinal cord would normally do that. Without that the child will develop hydrocephalus which can cause all sorts of mental issues, in addition to giving the child a sort of “alien head” problem which impacts their ability to fit in. Chiari malformation isn’t fixed by this, which can cause apnea and breath holding in some spina bifida cases. A decent number of children with Chiari 2 get a tracheostomy, which then requires 24 hour care, as the child can no longer audibly cry when on a ventilator, since the vocal cords are bypassed.
