More Information
Summary:A variable length headless compression screw insertion system includes a compression screw and a driver assembly for driving the compression screw into a bone. The compression screw has a bone screw and a compression sleeve coupled to the bone screw. The bone screw includes a proximal end having an external threading threadably received in the compression sleeve, and the compression sleeve includes a proximal end having a predefined drive feature and an external threading. The driver assembly includes a sleeve coupler adapted to threadably receive the external threading of the compression sleeve. A ram driver is coupled to the sleeve coupler and has a predetermined length such that its distal end is shaped to contact the proximal end of the bone screw to prevent translation of the bone screw relative to the compression sleeve.
