Figure 9From: Biomechanical evaluation of immediate stability with rectangular versus cylindrical interbody cages in stabilization of the lumbar spineThe distribution of normalized range of motion (median, quartiles and range) following cage insertion. (The ROM of intact motion segment is = 1). There was no significant difference between the two cage groups in flexion-extension (FE) and rotation (ROT). Although there was a trend of better stability in lateral bending (LAT) with rectangular cages, the difference was not significant.Back to article page
