  • Patent number: 7331263
    Abstract: The present application is directed to screwdrivers and methods of use for applying a controlled amount of torque to a fastener. In one embodiment, the screwdriver includes a shaft constructed of a material that is deformable upon the application of an excessive amount of torque. The deformation may cause the screwdriver to disengage from the fastener. In one embodiment, the tip of the shaft that engages the fastener is constructed of a material that deforms when an excessive amount of torque is applied to the fastener. The deformation causes the tip to disengage from the fastener. The deformation prevents the screwdriver from applying an amount of torque above a predetermined limit.

  • Patent number: 7329282
    Abstract: Embodiments of devices and methods for correcting a vertebral member and/or repositioning a vertebral device relative to the vertebral member. A vertebral device has been previously positioned relative to a vertebral member. Due to subsidence or other factors, the vertebral device has moved and is no longer in alignment. A positioning device is used for re-positioning the vertebral device. A delivery device is used for inserting a material to the vertebral member and/or vertebral device. The material is initially in a first state that is flowable to allow for insertion to the required location. The material changes to a second state that permanently fixes the position of the vertebral device relative to the vertebral member.

  • Publication number: 20080027543
    Abstract: A posterior arch prosthesis according to the present invention includes a main body, two transverse protuberances extending transversely from either side of the main body, articulating surfaces formed on each of the transverse protuberances, and a posterior protuberance extending posteriorly from the main body. The posterior protuberance is attached to a first vertebra from which the natural posterior arch has been removed such that the articulating surfaces are arranged in articulating contact with surfaces on an adjacent, second vertebra. The posterior protuberance includes an attachment to which native structure may be reattached upon attachment of the prosthesis to the first vertebra.

  • Patent number: 7303563
    Abstract: A orthopedic fixation system comprising a plate with an outwardly-extending member. A saddle may be mounted on the member and includes spaced-apart arms that form a channel to receive a rod. An engagement member may be mounted within the saddle to prevent escape of the rod. In one embodiment, the engagement member is attached to the saddle to apply a downward force on the rod and an upward force on the saddle to lift the saddle relative to the plate. A method of attaching an orthopedic rod is also included. In one embodiment, a rod is positioned within a channel in the saddle and a downward force is applied against the anchor which results in an upward force on the saddle to lift the saddle relative to the anchor.

  • Patent number: 7303562
    Abstract: This invention is a pedicle screw (1), comprising a threaded rod (2) having a longitudinal axis (XX) and a head (4) in which there is a channel (5) adapted to receive a spinal support rod, and a means for blocking the rod; the channel is formed such that its longitudinal axial plane (P) is inclined relative to the longitudinal axis (XX) of the threaded rod. The head (4) of the screw being made up of two flanks (6, 7), a threaded hole (11) is formed in one of them; the inclination of the channel (5) relative to the axis of the treaded rod (2) makes it possible to place a tool for blocking the rod in the channel without this tool coming into contact with the muscle tissues delimiting the incision. Moreover, the threaded seat (11) permits the positioning of instruments without obstructing the channel for passage of the rod.
