[Retracted] Introducing V-Line as a New Strategy to Choose Surgical Corridor in Oblique Lumbar Interbody Fusion at the L5-S1 Segment

Figure 1

Illustration showing the simulated surgical corridor. The midline of surgical corridor is at the center of the L5-S1 disc and the dorsal margin of surgical corridor is close to left iliac crest. Distance is the diameter of the surgical corridor (18 mm). is the traction distance of the left iliac vein. is the traction distance of the psoas major. is the tilt angle of surgical corridor.
