Bone Augmentation Material
Orthovita, Inc. introduces CORTOSS Bone Augmentation Material for treatment of vertebral compression fractures. According to the company, the material is an injectable, bioactive composite that mimics the physiological properties of human cortical bone and is the first alternative to polymethylmethacrlyate (PMMA) cement that has been evaluated in a clinical study and cleared in the U.S. The material exhibits:
- A blend of cross-linking resins and reinforcing fillers, which include a proprietary bioactive glass found in Orthovita's VITOSS™ Bioactive FOAM products.
- No methylmethacrylate monomer.
- A constant, paste-like consistency when being injected and the ability to set quickly to create a load bearing implant with the mechanical properties of human cortical bone.
- The ability to flow and fill into the existing intra-vertebral anatomy rather than displacing, as shown in a study, which may reduce the volume of material required for clinical success.
- A bioactive response that occurs at the implant's surface which promotes the deposition of calcium phosphate,strengthening the implant-bone interface, according to studies.
- Unique flow characteristics that allow low-pressure, manual delivery through Orthovita's ALIQUOT™ Delivery System.
- Mix-on-demand preparation allowing clinicians to stop material injection for an indeterminate amount of time and providing a high degree of procedural flexibility.
