The aim of this study was to accurately identify the distribution of sensory nerve branches running to bursa with mesoscopic dissection and boundaries following the injection of gelatin into the bursa. Eighteen shoulders of 11 Korean soft cadavers (average age, 65 years; age range, 43 - 88 years) were dissected. The most prominent point of greater tubercle of the humerus (GT) was used as a reference point. The horizontal line passing through GT was used as the x-axis while the vertical line passing through the GT was used as the y-axis. Average distances of the anterior, posterior, superior, and inferior from the GT were 1.9±0.6, 2.4±1.3, 2.1±0.7, and 3.2±1.5 cm, respectively. In 15 cases of 18 shoulders, the anterior branch of the axillary nerve was distributed to the subdeltoid bursa that was running posteriorly. The muscular branch of the anterior and middle parts of the deltoid was distributed to the branch of nerve that was running into the subdeltoid bursa. A branch of the posterior cord of brachial plexus was distributed to the subdeltoid bursa that was running anteriorly in three cases. Most of the branches of the axillary nerve were distributed into the posterolateral area. The branches of the posterior cord of brachial plexus were distributed in the anterolateral area. These results might be useful for preventing residual pain on the anterior shoulder region following an injection for the relief of shoulder pain.
本研究旨在通过胶原材料对肩峰下滑囊的注射，结合中观解剖，精确识别向滑囊分布的感觉神经分支的位置及其边界。18 个韩国成人尸体（平均年龄 65 岁；年龄范围 43-88 岁）的 11 个肩部被进行了解剖。我们以肱骨头大结节（GT）的最突出点作为参考点。穿过 GT 的水平线被用作 x 轴，穿过 GT 的垂直线被用作 y 轴。从 GT 到前方、后方、上方和下方的平均距离分别为 1.9±0.6cm、2.4±1.3cm、2.1±0.7cm 和 3.2±1.5cm。在 18 个肩部中的 15 个中，腋神经的前支分布到向后运行的肩峰下滑囊。三角肌前、中部的肌支分布到进入肩峰下滑囊的神经分支。在三个病例中，臂丛后束的分支分布到向前运行的肩峰下滑囊。腋神经的大部分分支分布到后外侧区。臂丛后束的分支分布在前外侧区。这些结果可能有助于预防肩部疼痛注射治疗后前肩部区域的残留疼痛。
