PathLoc-SI Sacroiliac Fixation and Fusion System allows for fusion and stabilization of the SI joint. It features two different types of screws - arch and locking. The design of the arch screw allows for ample bone graft packing to aid in fusion. Locking screws feature two different pitches on the proximal and distal ends to ensure strong fixation. If needed, surgeons may use washers with locking screws to help protect the patient’s bone.
