Suprascapular notch
Updates to Article Attributes
The suprascapular notch is located on the superior aspect of the scapula, at the scapula's anterolateral aspect.
Gross anatomy
The suprascapular notch separates the superior border of the scapula from the anterior coracoid process.
Relations and/or boundaries
The suprascapular nerve passes through the notch on its course over the scapula to the supraspinous fossa in the dorsal shoulder.
The superior transverse scapular ligament passes over the notch and attaches to the base of the coracoid process. The suprascapular artery passes over the ligament.
Variant anatomy
One classification system attempts to categorise variant suprascapular notch anatomy 2:
type I: no suprascapular notch
type II: there is a 'V' shape to the suprascapular notch, and it is located in the middle third of the superior border
type III: there is a 'U' shape to the suprascapular notch
type IV: similar to type II, but very small; the suprascapular nerve often passes through a groove next to the notch
type V: similar to type III, but very small, with a partially ossified ligament
type VI (4%): the transverse scapular ligament is completely ossified
