The cylinder was gradually thickened in the 3D reconstruction until it broke through the outer or inner wall of the superior articular process of the atlas (a, b), and this diameter of the cylinder was recorded. The implantation of the cylinder was simulated during the 3D reconstruction. The red portion is the length of the cylinder in the lateral mass of the axis, the yellow portion is the length of the cylinder in the atlantoaxial joint space, and the green portion is the length of the cylinder in the lateral mass of the atlas (c, d)
