Table I.

Measurements for the anterior circumflex humeral artery (ACHA) and its branches in relation to the greater tuberosity (GT) as well as the PCHA ascending branch into the GT

Measurement (mm) Description
1. ACHA length Length of the ACHA from its origin till the most medial crest of the bicipital groove (Fig. 2)
2. ACHA length in the bicipital groove Length of the ACHA between the most medial and most lateral crests of the bicipital groove; the portion of the ACHA that lies deep to the long head tendon of biceps brachii (Fig. 2)
3. Ascending branch length Length of the ascending branch of the ACHA from its origin at the most lateral crest of the bicipital groove to the point where this vessel enters the medial aspect of the GT (Fig. 2)
4. Ascending branch penetration point to the lateral aspect of GT (lp-GT) Distance from the point where the ascending branches penetrate the medial aspect of the GT to the most lateral point of the GT (lp-GT) (Figs. 2 and 3)
5. PCHA ascending branch penetration point to the lateral aspect of GT (lp-GT) Distance from the PCHA's ascending branch (PCHA-b) penetration into the GT to the most superolateral point of the GT (lp-GT) (Fig. 3)
