Atlas - Model HiJAK AC - Cervical Spine Spacer System
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.
Height & Lordotic range
Small 4.5mm starting height
2.5mm of continuous anterior expansion
and
1.25 mm of posterior expansion allowing for indirect decompression
Anatomic contour on cephalad endplate
Up to 20 degrees of lordotic correction
Footprint & Graft
Small and large footprint options
Unobstructed graft chamber
Post expansion graft-packing capability
Proprietary Subtractive Surface
Nano and mirco surface technology utilizing a proprietary subtractive process with decades of proven clinical history.

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.
