Abstract:
[Objective]To study cervical hollow threaded autograft cortical bone fixator with morselized bone for cervical anterior interbody fusion.[Method] Eighteen sheep were underwent cervical anterior discectomy and fusion with a hollow threaded and fenestrated tibial cortical hone fixator filled with morselized bone(diameter of 300~500 um) for C5、6 or autogenous iliac crest bone cylinder or C3、4 respectively.Cervical spines were radiographed immediately after surgery and 1,2,3 months later,the specimens of C5~6 and C3~4 were taken for histology investigation and biomechanical test respectively.[Result] Interbody fusion was achieved 3 months after surgery in experimental gronp and all but one in control group,with statisticdly significant difference was found between two groups in biomechanical compression and torsion tests of ante or post-fatigue test(P
