Surgical procedure for expanding a vertebral canal

摘要

To provide a method with which expansion of the vertebral canal of vertebrae is possible with less stress for the patient than with the surgical methods used to date, it is proposed that herein the vertebral arch be split and an incision gap thereby be formed, and the incision gap bounded by opposed incision surfaces be expanded to a prescribed gap width and the bone substance of the resulting vertebral arch sections thereby be elastically/plastically deformed.

1. Surgical method for expanding a vertebral canal of a vertebra, comprising:
a single splitting incision, the single splitting incision splitting a vertebral arch into vertebral arch sections to form an incision gap, the incision gap being bounded by opposed incision surfaces, and expanding the incision gap to a prescribed gap width such that the bone substance of the vertebral arch sections is thereby elastically/plastically deformed, wherein the expansion of the incision gap, with the bone substance of the vertebral arch sections thereby being elastically/plastically deformed, is performed such that forces acting on the incision surfaces are limited to about 500 N or less, preventing fracturing of lamina of the vertebral arch, wherein the single splitting incision is the only incision made in the vertebral arch.
