Fig. 4From: Kinematic characteristics of lumbar spinous processes during axial rotation in patients with lumbar degenerative disc disease lateral lumbar interbody fusion and interventionLocal coordinate systems were established at the tip of the process to measure 6DOF flexion(+)/extension(-); left bending(+)/right bending(-); left rotation(+)/right rotation(-); left translation(+)/right translation(-); posterior translation(+)/anterior translation(-); proximal translation(+)/distal translation(-);a degree (°) for rotation; b mm for translationBack to article page
