Clavicle – Acromioclavicular Joint (CAJ)[R,L] ISB
Landmark CAJ
The acromial joint surface of the clavicle is relatively flat. Its upper edge is next to the superior face of the clavicle (see Figs 7.1 & 7.2).
The palpator stands next to the sitting subject.
The point to locate is found after rotating the finger pulp slightly towards the clavicle.
Observe the superior face of the clavicle (if possible together with the scapula). Locate the acromioclavicular joint. The point to select (in red) is the center of the superior edge of the clavicular component of the joint (facing SAJ, in blue; see p. 60).
