Results from an efficacy study of ReVivo Medical's spinal fusion technology demonstrated that loadsharing through elastic micro-motion accelerates bone formation and interbody fusion.
In the study, 14 goats underwent anterior cervical discectomy and fusion receiving either a translationally dynamic or elastically deformable plate. At 18 weeks, subjects were evaluated by x-ray, computed tomography scan and undecalcified histology to evaluate bone formation and interbody fusion. The results indicated more than 46% improvement in bone growth vs. dynamic plates, with a superior rate and quality of fusion.
ReVivo Medical is developing elastic micro-motion implantable spinal devices, and expects first commercial sales within one year. Its cervical plate design and surgical methods are covered by four issued patents. Further, fourteen U.S. and ex-U.S. patents are pending, addressing a range of devices and instrumentation.
