Figures & data

Figure 1 Luna 3D® (Benvenue Medical Inc., Santa Clara, CA, USA) lumbar interbody fusion cage.

Notes: Major steps of deployment include (from left to right): (A) initial deployment of top and bottom components in a curved trajectory from a cannula (top and bottom images), (B) completion of top and bottom component deployment in a circular configuration, (C) initial advancement of middle component between top and bottom components, (D) completion of Luna 3D cage deployment, and (E) bone graft injection into implant concavity.

At 3 months, the patient is doing well clinically and reported complete resolution of low back and lower extremity pain.
