Among the innovations that Chipault made in neurosurgery were the removal of the underyling dura in meningiomas, a new laminectomy technique, development of small clamps for closing a scalp incision, the treatment of hydrocephalus by tapping the venticles through a burr hole. He proposed a scheme of craniectomies for treatment of craniosynostosis, and pioneered the use of wires and steel splints in the stabilization of the spine in trauma and deformities.
