Suprascapular notch
The suprascapular notch is a notch in the superior border of the scapula, just medial to the base of the coracoid process.
This notch is converted into a foramen by the superior transverse scapular ligament, and serves for the passage of the suprascapular nerve ; sometimes the ligament is ossified. The suprascapular artery travels superiorly to the superior transverse ligament.
According to, there are six basic types of scapular notch:
- Type I : Notch is absent. The superior border forms a wide depression from the medial angle to the coracoid process.
- Type II : Notch is a blunted V-shape occupying the middle third of the superior border.
- Type III : Notch is U-shaped with nearly parallel margins.
- Type IV : Notch is V-shaped and very small. A shallow groove is frequently formed for the suprascapular nerve adjacent to the notch.
- Type V : Notch is minimal and U-shaped with a partially ossified ligament.
- Type VI : Notch is a foramen as the ligament is completely ossified.
