20090318970Spinal Rod Connectors Configured to Retain Spinal Rods of Varying Diameters - A spinal rod connector is configured to accommodate a range of spinal rod diameters. The present spinal rod connector may take the form of a spinal rod screw head, hook, spinal rod connector or a spinal rod holder.
