Minimally Invasive Transforaminal Lumbar Interbody Fusion at L5-S1 through a Unilateral Approach: Technical Feasibility and Outcomes

Figure 7

Because of the orientation of the L5-S1 disc space, the tubular retractor when placed in line with the disc space can often be slanted. Resultant unnatural posture of the surgeon can cause fatigue to the surgeon. To avoid this, we tilt the operating table caudally so the tubular retractor is almost perpendicular to the floor.
