The circumflex scapular artery (CSA) has been described in detail in the literature, but the groove, i.e., the circumflex sulcus (CFS), formed by the artery on the lateral pillar of the scapula has been completely neglected. The aim of the present study was to describe the variability and anatomy of the CFS.
The study was based on the examination of 103 pairs of dry bone specimens of adult scapulae, i.e., 206 specimens, including 92 (46 pairs) male and 114 (57 pairs) female specimens. In the first step, quantitative criteria were defined for assessment of the CFS presence and type. Subsequently, statistical analysis of the obtained data was performed.
The study revealed considerable variability of the arterial groove, which was well developed in 33% (type A), shallow in 40% (type B), and absent in 27% (type C) of cases. The mean distance between CFS and the infraglenoid tubercle was 3.3 cm CI (3.1-3.3), which corresponds to the proximal third of the lateral border of the scapula.
The study has confirmed variability of the arterial groove (CFS) and its localization in relation to the inferior glenoid rim. The findings are clinically important, particularly in relation to the Judet approach to scapular fractures (localization of the CSA course).
旋肩胛动脉（CSA）在文献中有详细描述，但动脉在肩胛外侧柱上形成的槽，即旋肩胛沟（CFS），却完全被忽视了。本研究旨在描述 CFS 的变异性和解剖结构。
本研究基于对 103 对成人肩胛骨干骨标本的检查，即 206 个标本，包括 92 个（46 对）男性和 114 个（57 对）女性标本。在第一步中，定义了评估 CFS 存在和类型的定量标准。随后，对获得的数据进行了统计学分析。
研究显示动脉沟具有相当大的变异性，在 33%（A型）的情况下发育良好，在 40%（B 型）的情况下较浅，在 27%（C 型）的情况下不存在。CFS 与肩胛下结节之间的平均距离为 3.3cm CI（3.1-3.3），相当于肩胛外侧缘的近端三分之一。
本研究证实了动脉沟（CFS）及其在与肩胛下窝缘的关系中的变异性。这些发现具有临床重要性，特别是在涉及肩胛骨折的 Judet 入路（CSA 路线的定位）时。
