N2  - Although the triangular deltoid muscle has three distinct portions originating from the scapula and acromion, the underlying coraco-acromial ligament presents as the stabilizing factor for the anterior deltoid, thus bridging the interval within the coraco-acromial arch. As the deltoid muscle integrity is vulnerable during the resection of the coraco-acromial ligament from the acromion, the purpose of this study was to quantify the height of the del-toid muscle over the region of the coraco-acromial ligament.The superior shoulder region in seventeen nor-mal female individuals (n = 34) were bilaterally examined through an ultrasonographic system (Medelec Synergy: Acertys T2 EDX, 2012). In ad-dition to the length of the coraco-acromial liga-ment, the height of the deltoid muscle was meas-ured at three selected areas between the posterior aspect of the coracoid process and the anterior acromial tip, just superior to the coraco-acromial ligament.The mean coraco-acromial length was found to be 24.8±7.6mm. The mean deltoid height at re-gions 1, 2 and 3 were 8.4±2.7mm, 9.1±2.1mm and8.4±3.0mm, respectively.The height of the deltoid muscle was recorded to be constant across all three regions related to the coraco-acromial ligament. Moreover, the specific height of the deltoid muscle in the region of the coraco-acromial ligament was not reported in the literature reviewed. In addition, this study was done to complement the introduction of the delto-fulcral triangle model by Naidoo et al. (2017). The provision of data regarding the specific deltoid height may assist to preserve the deltoid muscle and the accompanying coraco-acromial ligament during operative procedures.
