The three dimentional stabitity provided by Alıcı spinal system has been studied in an in vitro biomechanical model usı'ng fresh calf thoracoiumber spine specimens. An injury was created at L1 vertebra, totally excising ante-rior longitidunal ligament and corpus, ieaving posterior elements intact. Maximum loading has been applied to this destabilized specimen and load-deformation curves were obtained. After mounting Alıcı spinal system to this in-stable specimen, it was observed that stability increased more than tvvice.
