Abstract Objective To explore the preliminary result of cervical uncovertebral joint fusion cage in an animal model of goat.Methods Anterior cervical discectomy and fusion using the uncovertebral joint fusion cage at C_3~4level were performed in 12 goats.Postoperative X-rays，CT scan and Micro-CT scan were performed for evaluation.Results No incision infection，nerve injury，vertebral artery injury，and implant failure were observed.The fusion rate is 75.0％ three months after operation and 83.3％ six months after operation demonstrated by CT scan.Micro-CT scan showed obvious trabecular bone in the lateral uncovertebral joint region and in part of goats obvious trabecular bone were observed around the cage.Conclusion Goat can be a good animal model for uncovertebral joint fusion cage.The uncovertebral joint fusion cage is a safe and feasible cage but future studies are needed.

Key words： goat animal model uncovertebral joint fusion cage cervical spine fusion Luschka joint
