New neurologic deficit and recovery rates in the treatment of complex pediatric spine deformities exceeding 100 degrees or treated by vertebral column resection (VCR).

A significant proportion of patients with complex spine deformity experience NND. However, significant improvement in neurologic function can be expected over time as seen in this study without additional surgical intervention in most cases. Congenital deformities accounted for 63% of the patients experiencing NND.
