The purpose of this study was to determine the location of the anterior humeral circumflex artery and axillary nerve based on bony landmarks, and to provide anatomical information that enables a safe approach when treating a proximal humeral fractures.
Thirty cadavers were included. The distances of both the anterior humeral circumflex artery and the axillary nerve from body landmarks were measured using Vernier calipers.
The mean distance between the inferior border of the medial acromion and the superior border of the anterior humeral circumflex artery was 5.1 ± 0.2 cm (range, 4.6-5.5 cm); the mean distance between the prominence of the lesser tuberosity and the superior border of the anterior humeral circumflex artery was 2.5 ± 0.2 cm (range, 2.0-3.0 cm); the mean distance between the anterior-inferior border of the acromion and the superior border of the axillary nerve was 6.3 ± 0.5 cm (range, 5.2-7.0 cm).
The artery is located approximately 5.1 cm below the inferior border of the medial acromion and 2.5 cm below the prominence of the lesser tuberosity, and the nerve was located approximately 6.3 cm below the anterio-inferior border of the acromion and 3.5 cm below the prominence of the greater tuberosity. The reduction manoeuvres should be conducted with extreme care in this region.
本研究旨在根据骨性标志确定肱骨头旋肱前动脉和腋神经的位置，并提供解剖学信息，以便在治疗肱骨近端骨折时安全进针。
共纳入 30 具尸体。使用游标卡尺测量肱骨头旋肱前动脉和腋神经与体部标志的距离。
肩峰内下缘与肱骨头旋肱前动脉上缘之间的平均距离为 5.1 ± 0.2 cm（范围，4.6-5.5 cm）；小结节隆突与肱骨头旋肱前动脉上缘之间的平均距离为 2.5 ± 0.2 cm（范围，2.0-3.0 cm）；肩峰前下缘与腋神经上缘之间的平均距离为 6.3 ± 0.5 cm（范围，5.2-7.0 cm）。
动脉位于肩峰内下缘下方约 5.1 cm，小结节隆突下方约 2.5 cm，神经位于肩峰前下缘下方约 6.3 cm，大结节隆突下方约 3.5 cm。在这个区域进行复位操作时应格外小心。
