Schematic procedure of ERAS TLIF. Initially, endoscopic discectomy (A) is done via an 8-mm channel (B). Subsequently, the vertebral endplate is prepared through a small working channel (C) with specialized instruments such as drill (D) and electric brush (E), etc. No soft tissue or muscular dissection is needed. An OptiMesh expandable cage (F, white arrow) is inserted and filled with allograft through a small tube. Finally, the cannulation of Jamshidi needles and guide wire are performed for the placement of percutaneous pedicle screws (G). ERAS, enhanced recovery after surgery; TLIF, transforaminal lumbar interbody fusion.
