Abstract: A system and method for providing fixation to a spine according to one example embodiment includes a hook portion with a plurality of planes of adjustment and an attachment portion connected to the hook portion. The attachment portion is configured to connect to the top of a pedicle screw to provide pedicular and laminar fixation to the spine at a vertebra to which the pedicle screw is connected.

Abstract: A medical implant device has in one embodiment a receiver member for receiving an elongated member, a crown member, an anchor member and a retaining member. An embodiment of the receiver member has an axial opening, a transverse channel, a chamber including at least one substantially flat wall, and a groove. An embodiment of the crown member has at least one substantially flat side. An embodiment of the anchor member has a head with at least one substantially flat surface that may be parallel to the anchor member's longitudinal axis, and an anchoring portion. An embodiment of the retaining member is a substantially flat clip. The crown member and anchor member are inserted into the chamber, and the retaining member is inserted into the groove beneath them. The anchor member may be pivoted substantially in one plane with respect to the receiver member until locked.

Abstract: The spinal rod system and perpendicular rod connector of the invention provides for a first rod to be connected by two pedicle screws transverse to the spine across a vertebra. The perpendicular connector is then connected to the first rod anywhere along the rod. The longitudinal spinal rod is then connected to the perpendicular rod connector using common connectors. The perpendicular connector is slidable along the first rod. By using the perpendicular rod connector, the amount of bending and the tolerances required is reduced as the connector may be slid along the transverse rod to accommodate the longitudinal rod. Known pedicle screws may be used with a slight bend placed in the transverse rod to accommodate the spinal column. Alternatively, the pedicle screws may be bent slightly such that a straight transverse rod may be used.
