摘要： A mechanism for fixing a spinal support to vertebrae includes a support member and a pedicle screw component. The support member comprises an elongated end comprising a longitudinal axis. A hook connects to the elongated end and receives the vertebrae. The hook is angled in three different planes with respect to the longitudinal axis. A connector section connects the elongated end to the hook and is angled with respect to the elongated end and comprises a thickness less than a thickness of the elongated end. The pedicle screw component comprises a fixation component anchored in the vertebrae. The fixation component comprises a socket; a screw head comprising a bulbous end that fits into the socket; and a channel that receives the elongated end. A pin causes outward expansion of the bulbous end; and a blocking mechanism is attached to the screw head and adjacent to the elongated end.

摘要： An interbody distractor and geometry trial instrument to measure a height and an angle for an associated implant includes a height handle and an expansion head coupled to the height handle that is adapted to be positioned in a vertebral body. A wedge sleeve is coupled to the expansion head, to control an angle of a first surface plate and a second surface plate of the expansion head when the wedge sleeve interacts with the expansion head. A wedge sleeve knob is adapted to drive the wedge sleeve linearly towards the vertebral body when the wedge sleeve knob is actuated. A height of the expansion head and an angle of the first and the second surface plate are measured to determine the height and the angle of the associated implant when the height handle and the wedge sleeve knob are actuated.
