RecruitingProcedureAutologous Human Umbilical Cord Tissue Patch for Postnatal Closure of Open Neural Tube DefectsThe purpose of this study is to determine the impact of an autologous umbilical cord patch for dural closure on the repair of open neural tube defect. The outcomes will evaluate successful defect closure, creation of a more capacious spinal canal, and reduction in inflammatory tissue response versus historical controls.
