肩胛上切迹Suprascapular notch)位于肩胛骨上缘,位于喙突英语coracoid process的内侧。

解剖构造

肩胛上切迹的上侧会被肩胛上横韧带英语superior transverse scapular ligament封住,形成一个孔洞英语foramen。让肩胛上神经英语suprascapular nerve通过(但肩胛上动脉英语suprascapular artery并没有通过,而是从韧带上方通过)。有时韧带会被骨化。[1]

根据Rengachary 等人 1979,肩胛上切迹分为六个基本型:[2]

  • 第一型(8%):无切迹。The superior border forms a wide depression from the medial angle to the coracoid process.
  • 第二型(31%):Notch is a blunted V-shape occupying the middle third of the superior border.
  • 第三型(48%):Notch is U-shaped with nearly parallel margins.
  • 第四型(3%):Notch is V-shaped and very small. A shallow groove is frequently formed for the suprascapular nerve adjacent to the notch.
  • 第五型(6%):Notch is minimal and U-shaped with a partially ossified ligament.
  • 第六型(4%):Notch is a foramen as the ligament is completely ossified.
