Question

when assessing the posture from the lateral view, plumb line should be anterior to all of the following except?
a) lateral malleolus
b) acromioclavicular joint
c) head of fibula
d) greater trochanter

Explanation:

To solve this, we recall the normal postural alignment from the lateral view using a plumb line. The plumb line (vertical reference) in normal posture is anterior to the lateral malleolus, head of fibula, and greater trochanter. The acromioclavicular joint (AC joint) is part of the shoulder girdle; the plumb line is posterior or at the AC joint (not anterior to it in normal lateral postural assessment). So the exception is the acromioclavicular joint.

Answer:

b) Acromioclavicular joint
