  • Patent number: 9775651
    Abstract: A vertebral fixation device and corresponding method of fixation hold a spinal vertebra on a rod. The device has a fixation element including a component of substantially U-shaped cross section with a first branch, a bottom and a second branch. A loop is formed by a flexible band for connecting the vertebra to the component, and which passes through recesses provided in the branches. Adjustable means for immobilizing the flexible band are provided. Those means include a connector screw having a head for longitudinal immobilization of the screw with respect to the first branch a thread for screwing in the second branch. A removable sleeve for passage of the screw, insertable in the first branch, in longitudinal abutment with the head of the screw is provided and presents a chamfered part designed to cooperate with the rod to compress the band between the rod and the bottom of the component.

  • Patent number: 9763722
    Abstract: The present invention relates to a system, method, device and kit which utilize a modular pedicle screw implant that does not require the use of a guide wire for implantation and can be assembled in situ. The system, method, device, and kit include a surgical instrument for implanting a modular pedicle screw comprising a cannula coaxially aligned with a modified trocar style instrument or surgical shaft. The surgical shaft contains a first member of a surgical shaft-inner pedicle bone screw member joint, illustrated herein as a locking taper, for securing an inner member of a pedicle screw thereto. The inner member of a pedicle screw is further adapted to couple to an outer pedicle sheath. In combination, the inner member of a pedicle screw and the outer pedicle sheath form a solid modular pedicle screw.

  • Patent number: 9757247
    Abstract: An intervertebral implant can include a core and a flexible end plate. The core can have a core body that is elongate along a first direction and defines first and second outer surfaces. The flexible end plate can define an inner surface and an opposed bone facing surface that is configured to abut a vertebral body. The flexible end plate can be coupled to the core such that at least a portion of the inner surface faces the first outer surface and is spaced from the first outer surface. The flexible end plate is configured to resiliently flex toward a compressed configuration such that as the flexible end plate flexes toward the compressed configuration, a first end moves relative to the core along the first direction and the portion of the inner surface moves toward the first outer surface.

  • Patent number: 9687277
    Abstract: An implantation system for treatment of a defective curvature of the spinal column comprises an elongated element, a first bone fixation element being fixedly attached to said elongated element, a second bone fixation element, and guiding structure through which the second bone fixation element is slidably and contactingly connected to the elongated element. The elongated element has bending resilience and/or torsional resilience for applying corrective force action to the spinal column. A special arrangement of the guiding structure provides automatical adjustment of the corrective force action in dependence of growth of the spinal column.
