    摘要: There is disclosed a system and method for dynamic stabilization which provides for distraction of the inter-vertebral space while still allowing a patient a substantial range of motion. In one embodiment, an inter-vertebral dynamic brace is used to maintain proper distraction. The dynamic brace is designed to allow the vertebrae to which it is attached to move through their natural arc, maintaining the correct instantaneous center of rotation. An adjustable tensioning device is used to maintain the proper distraction and compression forces to restore and maintain proper kinematics, while allowing the dynamic brace to move through an arc centered with respect to the center of rotation of the portion of the spine between the vertebrae. In one embodiment, a method is provided for adjusting the dynamic brace both with respect to the center of rotation of the vertebrae in both the flexion/extension axis and in the superior/inferior axis.

    摘要: A locking screw assembly is provided which allows installation into a plate-like member using relatively little force, but which requires relatively great force for removal. The fastener has an annular locking ring provided within a groove in the head of the screw to allow the screw to sit within or flush with the anterior surface of the plate. The through-hole in the plate which receives the locking screw comprises an entrance, a collar section, an undercut, and an exit. The locking ring resides within the undercut. The locking ring has a leading surface that is chamfered or radiused and a trailing surface that is flat. The chamfer allows the locking ring to easily be inserted into the through-hole by interacting with a lead chamfer in the entrance. After installation, the flat trailing surface abuts a lip adjoining the collar section and the undercut and prevents the screw from being easily removed from the through-hole.

    摘要: A locking screw assembly is provided which allows installation into a plate-like member using relatively little force, but which requires relatively great force for removal. The fastener has an annular locking ring provided within a groove in the head of the screw to allow the screw to sit within or flush with the anterior surface of the plate. The through-hole in the plate which receives the locking screw comprises a ledge and an undercut. When the fastener is installed into the plate, the locking ring resides within the undercut and is prevented from backing out by the ledge. The locking ring has a leading surface that may be chamfered or radiused and a trailing surface that may be flat. The chamfer allows the locking ring to easily be inserted into the through-hole by interacting with the through-hole. After installation, the trailing surface contacts the ledge.

    摘要: An instrument guide and implant holding device is provided which releasably secures an implant to the instrument guide. The device provides a convenient guide for surgeons to perform various operative techniques on the subject bone without the need for separate devices, and allows all these operative techniques to be performed without removing the instrument guide from the dissected area until all operative techniques have been completed. The releasable mechanism allows the surgeon to easily hold the instrument to an implant using a simple press-fit approach, and easily releases from the implant with a minimal amount of force. An embodiment also allows the surgeon to releasably lock the cannula in a given orientation about the centroidal axis of the implant fastener hole.
