Illustration of Ilizarov-type compression apparatus in IVD of mouse. (a). Schematic image of an Ilizarov-type coccygeal IVD compression apparatus. (b). General images of an Ilizarov-type compression apparatus produced 400 g axial stress for Co7-8 in the tail of mouse. The force between each springs and the ring was fixed at the same level in turn with sensors. (c). Lateral X-ray evaluation after installation of apparatus.
