ABSTRACT:
An apparatus for interconnecting a pair of longitudinal members connectable with vertebrae of a spinal column comprises first and second connector members connectable with the longitudinal members. An elongate plate extends transverse to the longitudinal members and interconnects the first and second connector members. The first connector member includes a hook portion extendable around a portion of the longitudinal member. A set screw clamps the longitudinal member to the hook portion of the connector member. A nut threadably engages the set screw to clamp the elongate plate to the connector member. The elongate plate includes surfaces defining a recess for receiving the connector member. The surfaces defining the recess engage the connector member to prevent the elongate plate from pivoting relative to the connector member.
