Figure 4

The calculated ROM at surgical L4-5 level in the INT, TLIFm, TLIFa, TLIFo models supplemented with: (A) Bilateral pedicle screw fixation or (B) Unilateral pedicle screw fixation. Translaminar facet screw was used in the model of TLIFo plus unilateral pedicle screw fixation (TLIFo + f). (Fl = Flexion; Ex = Extension; LLB = Left lateral bending; RLB = Right lateral bending; LAR = Left axial rotation; RAR = Right axial rotation).
