ARCH® Fixation System

Division: Spine
Category: Cervical

The ARCH ® Fixation System is a system of implants and instruments for open door laminoplasty procedures. It is designed for use in the lower cervical and upper thoracic spine to maintain an expanded spinal canal, secure spinal stability and preserve the protective function of the spine after a laminoplasty is performed.

ARCH Fixation System’s miniplates and screws are designed for use with the ARCH ODL spacer. Arch ODL spacers are designed by and available through DePuy Synthes Spine and are processed by the Musculoskelatal Transplant Foundation (MTF).

Indications for Use
