  • Publication number: 20220071663
    Abstract: A method and suture anchor for treatment of spinal stenosis. The method includes the steps of cutting off a muscle origin or insertion from a spinous process, cutting off the spinous process at the transition to the lamina arcus vertebrae, at least partial resection of the lamina arcus vertebrae and thereby decompression of the spinal cord within the foramen vertebral, performing osteosynthesis of the spinous process, and placing a suture anchor within the spinous process and reattaching the muscle origin or insertion to the spinous process. Further methods for spine stabilization are provided wherein suture anchors are used to implement a tension band wiring. Further methods for reduction of unwanted effects after spinal treatment are provided.

  • Patent number: 11179179
    Abstract: An implant system that is designed to be fastened to a posterior side of a spinal column. The implant system includes an implant body, for example a plate, and a plurality of fasteners. The implant body has a fastening structure for each fastener. Each fastener extends between a proximal end and a distal end and includes a thermoplastic material in a solid state, the thermoplastic material being liquefiable by energy impinging on the fastener, in an anchoring process, in which the fastener is pressed against bone tissue by a pressing force acting from a proximal side, and in which energy is coupled into the fastener to at least partially liquefy the thermoplastic material, wherein a flow portion of the thermoplastic material is pressed into bone tissue and, after re-solidification, anchors the fastener in the bone tissue.

  • Publication number: 20200138495
    Abstract: A spinal implant system with a spinal anchor implant, for example a pedicle screw, that has a head portion forming the proximal end. Further, the system includes a support plate, which is shaped to be placed against the posterior or lateral side of the vertebra and having an anchor receiving structure. The anchor implant extends through the anchor receiving structure into the bone tissue when the anchor implant is anchored in the bone tissue with the support plate between the head portion and the bone tissue. The system also has a thermoplastic material in a solid state, which is shaped and equipped to be placed relative to the anchored anchor implant and the support plate and to be made flowable by the impact of impinging energy so as to bridge and at least partially fill a gap between the anchor implant and the support plate.
