Fig. 4

The virtual trajectory was placed into the L4-5 (A-H) and L5-S1 (I-P) intervertebral foramina through a series of predefined angulations. For each angulation, AP and lateral virtual fluoroscopies of the lumbar spine and the virtual trajectory were taken. Lateral: A, B, C, D, I, J, K, and L; AP: E, F, G, H, M, N, O, and P; CA: A-H 10°, I-P 30°; CACAP: A, E, I, and M 0°; B, F, J, and N 15°; C, G, K, and O 30°; D, H, L, and P 45°
