Illustration of the method used to define the acromial axes. Using the undersurface acromion viewing plane, a plane is inserted that bisects the acromial box longitudinally (the ‘longitudinal lateral acromial plane’[LLAP]). A second plane is inserted that bisected the acromial box transversely (the ‘transverse lateral acromial plane’[TLAP]). The junction of these planes with the bone along the inferior border of the acromion at their intersection, the most anterior, posterior and lateral points are marked with pivots. These pivots are connected to create the LLAP and TLAP
