Figure 3From: Biomechanical comparison of unilateral and bilateral pedicle screws fixation for transforaminal lumbar interbody fusion after decompressive surgery -- a finite element analysis Comparison of ROM calculated for the five levels of intact lumbar spine (INT) with previous studies: (A) loading of 3.75 N-m and 7.5 N-m pure moments in the INT models; (B) loading of 10 N-m moments with 150 N preload in the INT models.
