    • The present invention provides a Posterior Dynamic Stabilization (PDS) device that allows elongation, which is a critical requirement for a PDS device as it allows pedicles to travel naturally in flexion, extension, and lateral bending of the spine. This interpedicular travel preserves a more natural center of rotation unlike other PDS devices that simply allow bending. In particular, the invention involves a PDS spring rod, wherein the helix is created with composite flow molding (CFM) technology and comprises a polymer matrix reinforced with continuous carbon fibers, wherein the fibers are oriented substantially parallel to the centerline of the helix, thereby creating a high strength spring.
    • 本发明提供了一种允许伸长率的后置动态稳定(PDS)装置,其是PDS装置的关键要求,因为它允许椎弓根在脊柱的弯曲,延伸和侧向弯曲中自然地行进。 与其他简单允许弯曲的PDS设备不同,这种间隙行程保留了更自然的旋转中心。 特别地,本发明涉及一种PDS弹簧杆,其中螺旋是用复合流动模制(CFM)技术制成的,并且包括用连续碳纤维增强的聚合物基体,其中纤维基本上平行于螺旋的中心线取向,由此 创造高强度的春天。

    • Various bone screws and methods for accommodating stiffness regions in bone are provided. The bone screw provided generally includes a receiver member configured to receive a fixation element and an elongate shank having different stiffness regions. In one embodiment, the elongate shank can include at least one slot for increasing the flexibility of the slotted portion of the elongate shank. In another embodiment, the elongate shank can be manufactured from materials selected to alter the stiffness of the shank. The different stiffness regions allow the bone screw to mimic the flexibility of bone, reducing the risk of fracture of the bone and/or loosening of the bone screw.
    • 提供了用于容纳骨骼中的刚度区域的各种骨螺钉和方法。 提供的骨螺钉通常包括构造成接收固定元件和具有不同刚度区域的细长柄的接收器构件。 在一个实施例中,细长柄可以包括至少一个狭槽,用于增加细长柄的开槽部分的柔性。 在另一个实施例中,细长柄可以由选择用于改变柄的刚度的材料制成。 不同的刚度区域允许骨螺钉模仿骨的柔性,降低骨折和/或松动骨螺钉的风险。

    • An intervertebral disc prosthesis comprises a first endplate, a second endplate, and a bearing surface positioned between the first endplate and the second endplate. The bearing surface may be provided by a mobile bearing disc including a convex bearing surface configured to engage the first endplate and a concave bearing surface configured to engage the second endplate. The multiple bearing surfaces of the mobile bearing disc engage articulating surfaces on the endplates to form a plurality of articulating joints. Each articulating joint is configured to facilitate a particular type of movement for the segmental unit. Furthermore, each articulating joint is defined by a distinct center of rotation. The contact pair formed by the convex bearing surface of the bearing component and the concave bearing surface of the first endplate may provide a flexion/extension center of rotation for the prosthesis. The contact pair formed by the convex bearing surface of the bearing component and the concave bearing surface of the first endplate may provide a lateral bending/torsional center of rotation for the prosthesis.
    • 椎间盘假体包括第一端板,第二端板和位于第一端板和第二端板之间的支承表面。 轴承表面可以由移动轴承盘提供,该移动轴承盘包括构造成接合第一端板的凸形支承表面和构造成接合第二端板的凹形支承表面。 移动轴承盘的多个支承表面接合端板上的铰接表面以形成多个铰接接头。 每个铰接接头被构造成便于分段单元的特定类型的运动。 此外,每个铰接接头由不同的旋转中心限定。 由轴承部件的凸形支承表面和第一端板的凹形支承表面形成的接触对可以为假体提供弯曲/延伸的旋转中心。 由轴承部件的凸形支承表面和第一端板的凹形支承表面形成的接触对可以为假体提供横向弯曲/扭转中心。
