Fig. 1From: Kinematic characteristics of lumbar spinous processes during axial rotation in patients with lumbar degenerative disc disease lateral lumbar interbody fusion and intervention a MR image of human lumbar spine of DDD patients. b 3D anatomical vertebral model from L2 to L5 constructed using the MR images. Local coordinate systems at the tip of spinous process were used to calculate the relative 6DOF kinematics of the proximal spinous process with respect to distal spinous processBack to article page
