Surgical correction consists of two methods: (i) fusion of two or more vertebrae levels using anterior cervical fixation plates commonly called anterior cervical decompression and fusion (ACDF) surgery and (ii) the total replacement of the diseased disc commonly called total disc replacement (TDR) surgery. ACDF is aimed at inhibiting the motion of the diseased segment; whereas, TDR uses a ball and socket device to restore the motion of the segment. The purpose of this study is to investigate the effect of bone condition on the two types of surgical techniques (TDR and ACDF or fusion) in cervical spine. An accurate 3D model of the cervical spine along with part of skull and first thoracic vertebra (C0-T1) is developed and subsequently used for finite element analysis of two different reconstructs. Compressive load along with various rotational moments simulating different spine motions were applied. Finite element analysis (FEA) has shown that variation of bone quality had the least effect in the stress profile, but it had a decreasing trend in the case of strain. Because of greater stresses on the bone, fusion surgery should not be a convenient method of surgical intervention for weak bone. For weak bone, TDR surgery is the most preferred option. %8 2019-08-27
