Atlas - Model HiJAK AC -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.
