Abstract
Four versions of clamps originally slidable along two generally parallel spinal rods are swivel connected to three versions of transverse connectors located between the rods. Set screws lock the transverse connectors to the clamps. Two of the clamp versions use interfitting rotational index locking detents at the swivel connections to fix the final orientation of the transverse connector relative to the spinal rods. The other two clamp versions use locking tapers to lock the rotational index positions at the swivel connections to fix the final orientation of the transverse connector relative to the spinal rods. One clamp version uses a separate set screw to fix the clamp on the spinal rod. One transverse connector has an open clamping head for installation directly onto the spinal rod without sliding it onto the rod from one end or the other.
