Arch Fixation System for Laminoplasty

The Arch Fixation System is indicated for use in the lower cervical and upper thoracic spine (C3T3) after a laminoplasty has been performed. The Arch Fixation System holds or buttresses the allograft in place in order to prevent the allograft from expulsion or impinging on the spinal cord.

The Arch Fixation System supports the Open Door technique of laminoplasty surgery and comprises titanium implants, trail spacers for allografts, and instruments. The objectives of the system are to expand the spinal cord, secure spinal stability, and preserve the protective function of the spine.

The system uses pre-bent miniplates that are designed to follow the anatomy of the cervical spine. The miniplates are longer on the lamina and shorter on the lateral mass. A slot on the miniplate allows a screw to hold the graft in position and eliminates its migration towards the spinal cord.


The system features 2.0 mm self-drilling and self-tapping screws as well as 2.4 mm rescue screws.


Instruments designed specifically for the graft and miniplate reduce OR time.
