Resorbable Tack Fixation System

The system is indicated for fractures of the craniofacial skeleton and reconstructive procedures of the midface and craniofacial skeleton. The resorbable tacks and the existing, approved 1.5mm resorbable screws are very similar in design and size. They are manufactured from the same polymer and in the same processes. Both products are made from 70:30 poly (L/DL)-lactide. The tacks are inserted into predrilled holes in bone to secure resorbable plates and provide rigid fixation. The implants utilize circumferential ribs to provide sufficient retention. Compared to the existing 1.5mm resorbable screws, the tacks provide comparable strength in pull-out and shear over time. The driver grasps the tacks around the head to provide retention during use. During insertion, an intemal shaft automatically disengages the tacks from the instruments and drives the tack head into the countersunk holes of the resorbable plates. Thus, surgical operative time is reduced because the holes are drilled, not tapped, and the tacks are pressed into bone holes rather than threaded in, as the resorbable screws are.
