解剖構造
肩胛上切跡的上側會被肩胛上橫韌帶封住，形成一個孔洞。讓肩胛上神經通過（但肩胛上動脈並沒有通過，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.
