Advanced Biomaterials for Spinal Fusion
Introducing PEEK OPTIMA™ HA Enhanced by CA Medical
How It Works
During spinal fusion surgery, the implant is positioned between vertebrae to stabilize the spine and encourage fusion.
Hydroxyapatite (HA), a naturally occurring component of bone, is embedded throughout the implant—not just coated on the surface—promoting consistent bone on-growth.
The radiolucent nature of PEEK allows for precise imaging during recovery, enabling surgeons to monitor healing and fusion over time.
Why It’s Advanced
Osteoconductive Throughout
Bone-Mimicking Stiffness
Clear Post-Op Imaging
FDA-Cleared and CE-Marked
Clinical & Preclinical Evidence
Human Case Series
Solid lumbar and cervical fusion seen at 6 months
Ongoing studies, including those evaluating the CA Medical Lumbar Interbody Fusion Device, continue to confirm the safety and efficacy of PEEK OPTIMA™ HA Enhanced in spinal procedures.
Key Features & Benefits
Hydroxyapatite Integration
Fully integrated HA (not surface coated) enhances bone apposition and early fusion on all implant surfaces.
Osteoconductive Surface
Promotes faster bone on-growth compared to traditional PEEK.
Reduced Subsidence Risk
Lower rates of implant sinking compared to metal cages in cervical fusion studies.
Bone-Like Mechanical Properties
Matches the elasticity of human bone to support natural bone remodeling.
Trusted by Leading Spine Surgeons
“I’m impressed by the solid arthrodesis around the PEEK OPTIMA™ HA Enhanced implant seen as early as 3 months.”
— Dr. Sigurd Berven, UCSF
“I’m routinely seeing evidence of bone bridging and fusion as early as 3 months. I’m fascinated by the cortical-appearing bone surrounding the cage.”
— Dr. Christoph Hofstetter, University of Washington
