Objectives This biomechanical study was designed to establish the Goat Cervical Ligament Complex Injury Model and to investigate the stability and motion preservation of a novel posterior fixation using bio-derived freeze-dried tendon.Methods The experiments of the current study were conducted in vitro and in vivo.Fifteen fresh-frozen goat spines (C 1-C7) were used in vitro and randomly divided into three groups: Intact (n=5);injury model group (n=5): bilateral facet joint fixation group (n=5).In vivo part, fifteen health adult goat were divided into three experimental groups and tested: (a) group: Intact (n=5);(b) injury model group: destabilized by means of complete resection of the cervical spine ligament complex of C3-4 (n=5);(c) bilateral facet joint fixation group: stabilization with bio-derived freeze-dried tendon, which were cross-fixed with "8" shaped in the 3-4 cervical bilateral facet joints(n=5).
