Abstract: A collinear reduction clamp including a compression rod, an arm, and an advancing mechanism for moving the compression rod relative to the arm. In some examples, the rod may include a cannulated bore to enable a bone screw to be inserted therein. The rod may also include a cap. The cap including a bone screw washer. In use, a bone screw can be inserted through the cannulated bore of the rod, the bone screw passing through the washer thereby coupling the washer to the bone screw thereby enabling both the bone screw and the washer to be inserted into the patient's bone directly at the compression site. In some examples, the cannulated bore may be used in combination with first and second tubes and a guidewire to enable a cannulated bone screw to be inserted therein. In some examples, the arm may be configured as a length adjusting arm.

Abstract: An orthopedic implant including an outer surface and at least one opening extending through the outer surface for receiving a fastener for coupling the implant to a patients bone or bone portion/fragment. The opening including a plurality of fins circumferentially disposed about the opening for engaging threads formed on a head portion of the fastener to secure the fastener to the implant. The plurality of fins being arranged and configured in first and second vertically spaced rows of fins. At least one of the fins including a different configuration, property, etc. relative to at least one of the other plurality of fins. In one embodiment, each of the first and second fins in a vertically stacked relationship includes a different configuration from the other of the first and second fins in that stack. In one embodiment, the different configuration includes a different length, a different thickness, or a combination thereof.
