BONE FIXATION SCREW AND METHOD

摘要

A screw device for compressing and fixing together a proximal and distal bone part along a surgical axis comprising: a bone screw portion comprising an elongate body inscribed with bone screw threads at a leading end of an outer surface of said body; an elongate tubular torque stabilizer portion for spanning said bone parts and comprising one or more torsion stops to engage each bone part to limit rotational movement between the bone parts and a translation stop on said torque stabilizer to seat against a portion of the proximal bone to limit translation of said torque stabilizer portion along the surgical axis; and a compressor lock portion engaging the bone screw portion and torque stabilizer portion to draw said bone screw portion proximally along the surgical axis toward said translation stop therein compressing said bone parts together.

1. A method for compressing and fixing together a proximal and distal bone part along a surgical axis using a bone screw device comprising the steps of:
advancing a bone screw portion along a surgical axis through a proximal bone part until seated at a predetermined location within a distal bone part; advancing an elongate tubular torque stabilizer portion along said surgical axis wherein one or more external torsion stops extend within a portion of each of the proximal and distal bone parts to limit rotation therebetween; and rotatably engaging a compressor lock along said surgical axis with a fastener portion of said bone screw portion consequently drawing together said bone screw portion and said compressor lock thereby compressing and fixating proximal and distal bone parts together.
