ACADIA™ – Facet Replacement System (currently in FDA study)

ACADIA_final_constr219D92B-300x296.jpgACADIA Facet Replacement System for treating lumbar spinal stenosis

The ACADIA™ facet replacement system is a chrome cobalt pedicle screw-based replacement for the facet joints in the lumbar spine. The device is designed to allow complete decompression of the spinal cord and nerve roots while potentially allowing the spine to return to normal physiologic motion. A potential advantage to replacing the facet joints with the ACADIA™ device is avoiding a fusion procedure, which may cause a permanent loss of motion in the spine.

ACADIA™ is quite unique; no other implant reproduces the anatomic design of the normal facet joints. The ACADIA™  facet replacement comes in numerous sizes, which allows the spine surgeon to customize the implant to mimic the normal facet joint in the patient. It is attached to the bone through pedicle screws, which have been used extensively in hundreds of thousands of patients since the mid-1980s.

NOW ENROLLING: Cervical: M6-C Overview

The M6 artificial cervical disc offers an innovative option for artificial cervical disc replacement because of its unique design which is based on a natural disc’s qualities. Engineered to replicate your own disc, the M6 is the only artificial disc that incorporates an artificial nucleus (made from polycarbonate urethane) and a woven fiber annulus (made from polyethylene). The M6 artificial nucleus and annulus are designed to provide the same motion characteristics of a natural disc. Together, the M6’s artificial nucleus and annulus provide compressive capabilities along with a controlled range of natural motion in all 6 degrees of freedom along each vertebra. This “natural” motion is designed to provide the freedom to move your neck naturally. The M6 has two titanium outer plates with keels for anchoring the disc into the bone of the vertebral body. These outer plates are coated with a titanium plasma spray that promotes bone growth into the metal plates, providing long term fixation and stability of the disc in the bone.

Artificial Disc Components

Artificial Nucleus

•Viscoelastic polymer designed to simulate native nucleus

•Allows physiologic axial compression

•Retained between endplates & fiber annulus matrix

•Designed to enable physiologic Center Of Rotation

Artificial Annulus

•Ultra High Molecular Polyethylene (UHWMPE) fiber material

•Intended to simulate native annulus & its performance

•Designed to provide controlled physiologic motion in all planes and axes

•Robust fiber matrix with multiple layers similar to native annulus


•Designed to minimize tissue in-growth & debris migration

•Allows for full range of motion


•Titanium endplates with tri-keel design

•Titanium Plasma Spray (TPS) coated endplate

•Low profile keel height (2mm)
