A cutaneous branch of the suprascapular nerve was observed in 6 arms from 5 (4 male and 1 female) out of 61 Japanese cadavers. The suprascapular nerves with a cutaneous branch arose from essentially normal brachial plexuses. Every suprascapular nerve with a cutaneous branch had a normal course, and gave rise to the cutaneous branch either from the upper of its two muscular branches to the supraspinatus or from its stem under the superior transverse scapular ligament. After passing between the coracoclavicular and coracoacromial ligaments the cutaneous branch pierced the deltoid muscle close to the tip of the acromion. In one case, the peripheral distribution was very carefully dissected, the nerve supplied the proximal third of the lateral aspect of the arm within the territory of the axillary nerve. A cutaneous branch of the suprascapular nerve is obviously not uncommon, at least in Japanese.
在61具日本尸体中，有5具（4男1女）的6条手臂观察到肩胛上神经的皮支。带有皮支的肩胛上神经起源于基本正常的臂丛神经。每条带有皮支的肩胛上神经走行正常，其皮支要么发自其至冈上肌的两个肌支中上方的那个肌支，要么发自肩胛上横韧带下方的主干。皮支在喙锁韧带和喙肩韧带之间穿过，在靠近肩峰尖处穿入三角肌。在1例中，非常仔细地解剖了其外周分布，该神经在腋神经支配区域内为臂外侧近端三分之一提供神经支配。肩胛上神经的皮支显然并不少见，至少在日本人中是这样。
