Which of the following describes the lumbar spine facet joint arthrokinematic motion during (L)lateral flexion in the neutral position?
A) Ipsilateral facet moves caudal and anterior; contralateral facet moves caudal and lateral.
B) Ipsilateral facet moves cephalic and posterior; contralateral facet moves caudal and posterior.
C) Ipsilateral facet moves caudal and anterior; contralateral facet moves cephalic and posterior.
D) Ipsilateral facet moves cephalic and medial; contralateral facet moves cephalic and medial.

Question

Quizplus · Accepted Answer

During lateral flexion in the neutral position, the ipsilateral facet of the lumbar spine moves caudal and anteriorly while the contralateral facet moves cephalic and posteriorly. This is due to the orientation of the facet joints and the movement of the vertebral bodies during lateral flexion. Option A and B are incorrect because they do not accurately describe the arthrokinematic motion during lateral flexion. Option D is incorrect because it describes a motion that does not typically occur in the lumbar spine during lateral flexion.
