HA Peek Drives Faster Fusion
Hydroxyapatite (HA) is a naturally occurring mineral and the main inorganic component of bone. It is well-known for its osteoconductive properties and enhancing bone apposition with a variety of implants.
Talos® (HA) and the PEEK-OPTIMA HA Enhanced Technology
Meditech Spine is the first company to offer a full line of HA Peek interbodies for both lumbar and cervical fusions through its Talos® family of IBF devices.
About the Peek-Optima® HA Enhanced Polymer
Hydroxyapatite (HA) is a naturally occurring mineral and the main inorganic component of bone. It is well-known for its osteoconductive properties and enhancing bone apposition with a variety of implants. Due to its well documented success for use in the cervical spine, PEEK-OPTIMA® Natural is currently the most common material used for interbody spinal devices. Surgeons are continually looking for ways to increase bone apposition with the existing armamentarium of spinal implants and one attempt has been to apply an exterior coating like Ti plasma or HA to IBF devices. This approach has yielded marginal improvement in bone fusion velocity and quality, the main draw-back being the limitation of coating only the exposed surfaces of the implant that contact the endplates of the vertebral body. However, by combining two clinically proven biomaterials (PEEK-OPTIMA® Natural and HA) together into one homogenous compounded polymer—Meditech Spine is able to offer a superior solution, the Talos® (HA) interbody system. With these combined materials, where all surfaces of the implants are infused with HA, Meditech now offers a bioactive implant that contributes to a more rapid healing process.
Does PEEK/HA Enhance Bone Formation Compared With PEEK in a Sheep Cervical Fusion Model?
Incorporating HA into PEEK provides a more favorable environment than PEEK alone for bone ongrowth. Cervical fusion was improved with PEEK-HA compared with PEEK alone as well as allograft bone interbody devices.
