You can spin a disc, or burn a disc, but when you blow a disc in your back the fun stops, and Amedica steps in. The company develops, manufactures, and commercializes joint and spine implants made of silicon nitride ceramic, a material thought to be more durable, resistant, and patient-compatible than traditional implant materials. Amedica's lead product candidates are its Valeo spinal implants which are intended to restore and maintain vertebrae alignment in the neck and lower back. Valeo spinal spacer implants have received FDA and EU approval for use as vertebra replacements. The company's other candidates include ceramic hip and knee implants with material that mimic the porous structure of natural bone.
