Objectives:To determine the initial stability of a novel construct in one-level cadaveric cervical spine model by comparing it with a conventional method.Methods:Twelve fresh human cadaveric cervical spines (C3~C7) were randomly divided into two groups:the test group:one-level corpectomy of C5 and three cortical iliac step-cut grafting with absorbable screw fixation; the control:one-level corpectomy of C5 and three cortical iliac strut grafting with anterior plate fixation.Two tests were performed:flexibility test and graft push of strength test.The two tests were proceeded before and after grafting and fixation.The range of motion(ROM),neutral zone(NZ) and graft push out strength(POS) were obtained.
