The main objective of this study was to perform experimental and numerical investigation on human C5-C6 cervical spinal segment before and after discectomy using the Cloward operation technique and to evaluate compare the stiffness of cervical spines before and after the operation. For the purposes of experimental investigations the cervical spines of four cadavers underwent biomechanical testing. Consequently, in order to perform numerical analysis three-dimensional geometrical and mechanical finite element model of the C5-C6 cervical spinal segment has been constructed. The second step of the investigation was to perform an operation on harvested spines, which corresponded to construction of FEM model of vertebrae after discectomy Experimental and numerical investigations have been accordingly compared.
