An implant is provided which allows for widening of the vertebral canal of vertebrae with less stress on the patient than in heretofore customary surgical procedures, wherein the vertebral arch of a vertebra is cut through, forming an incision gap, or is partially removed and the implant is inserted in the incision gap, wherein the incision gap is bounded by incision faces opposed to each other and the implant comprises an implant body having two contact faces which in the inserted state in the incision gap contact the incision faces of the vertebral arch.

Surgical implant for widening a vertebral canal

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.

Surgical procedure for expanding a vertebral canal

To facilitate the insertion of bone screws into a bone plate, a magazine for receiving at least one bone screw is proposed, which comprises a device for releasably securing the magazine to a bone plate, a receiving chamber extending continuously from the upper side to the underside of the magazine, a bone screw being arranged in the receiving chamber in such a way that when the magazine is secured to the bone plate, the distal tip of the bone screw is directed at a screw-in opening in the bone plate, and the proximal end of the bone screw is accessible to a screwing-in tool from the upper side of the magazine, and a fixing device for releasably fixing the bone screw in the receiving chamber. The invention also relates to a bone plate having at least one such magazine releasably secured thereto.
