解剖構造

肩胛上切跡的上側會被肩胛上橫韌帶英语superior transverse scapular ligament封住,形成一個孔洞英语foramen。讓肩胛上神經英语suprascapular nerve通過(但肩胛上動脈英语suprascapular artery並沒有通過,而是從韌帶上方通過)。有時韌帶會被骨化[1]

根據Rengachary et al. 1979,肩胛上切跡分為六個基本型:[2]

  • 第一型(8%):無切跡。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.
