解剖构造
肩胛上切迹的上侧会被肩胛上横韧带封住，形成一个孔洞。让肩胛上神经通过（但肩胛上动脉并没有通过，而是从韧带上方通过）。有时韧带会被骨化。[1]。
根据Rengachary et al. 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.
