  • Locking variable length compression screw
    Patent number: 11957393
    Abstract: 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.
    Type: Grant
