ABSTRACT:
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.
