Pathological craniocervical junction with an abnormal clivo-axial angle in flexion. Upon full flexion of the craniocervical junction, mathematical analysis demonstrates that the increase in the tangent arc creates a deformative strain approaching ε = 0.2. In vivo and in vitro models demonstrate loss of function with strains of 0.2
