HiJAK AC
The HiJAK AC Spacer System, the FIRST expandable cervical interbody with ADJUSTABLE HEIGHT and LORDOSIS, was designed for the surgeon who recognizes the importance of lordotic restoration and sagittal balance of the cervical spine.
Clinical studies have shown significant short and long term benefits to restoring sagittal balance to the cervical spine. Adjacent level disc disease and other co-morbidities have been attributed to a lack of proper sagittal balance postoperatively.

With Hyper-Lordotic options up to 20 degrees, HiJAK AC's expandable capability allows surgeons the opportunity to:
-
Adjust its lordotic angle to each patients' specific needs.
-
Incrementally adjust each level to "dial in" overall global balance.
-
Require less cortical endplate removal for implant fit.
-
Reduce the impaction force required to seat the cage.
-
Rely less on distraction pins for implantation of higher lordotic angles.
