The literature is deficient in studies aimed at quantifying the occurrence of a suprascapular artery traversing the suprascapular notch with the suprascapular nerve.
MATERIAL/METHODS: We have performed a cadaveric study using 60 adult specimens (120 sides). Thirty-eight specimens were male and twenty-two were female.
Our findings conclude that in this group, the suprascapular artery travels with the suprascapular nerve through the suprascapular notch in 2.5% of specimen sides. Both specimens in whom this occurred were male.
We hypothesize that this anatomic anomaly may also constitute a possible unrecognized mechanism in which shoulder pain is generated. Further studies focused at various races and the presence of this peculiarity are now needed to confirm our findings. In addition, unexplained chronic shoulder pain may be explored with vascular studies aimed at identifying the course of the suprascapular artery.
目前文献中缺乏旨在量化肩胛上动脉与肩胛上神经一同穿过肩胛上切迹发生率的研究。
材料/方法：我们使用60个成人标本（120侧）进行了尸体研究。其中38个标本为男性，22个为女性。
我们的研究结果表明，在该组中，2.5%的标本侧肩胛上动脉与肩胛上神经一同穿过肩胛上切迹。出现这种情况的两个标本均为男性。
我们推测这种解剖变异可能也是导致肩部疼痛的一种未被认识的潜在机制。现在需要针对不同种族以及这种特殊性的存在进行进一步研究以证实我们的发现。此外，对于不明原因的慢性肩部疼痛，可通过旨在确定肩胛上动脉走行的血管研究进行探索。
