Total 3D Airo® Navigation for Minimally Invasive Transforaminal Lumbar Interbody Fusion

Figure 2

A 63-year-old female with two-level stenosis and instability. Pre-op MRI showed foraminal stenosis of left side in L4/5 (a) and right side in L3/4 (b). From navigation screen, foraminal heights were measured preoperatively and postoperatively. L3/4 and L4/5 of left side increased from 19.6 mm and 11.7 mm to 21.3 mm and 17.4 mm, respectively (c). L3/4 of right side increased from 17.7 mm to 20.1 mm (d). L4/5 of right side increased from 18.5 mm to 20.8 mm (e). The disc height of L3/4 and L4/5 increased postoperatively (f). The local lordosis improved postoperatively (g).
