Updates to Article Attributes
Body
was changed:
Thesuprascapular 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 from the anterior coracoid process.
Relations and/or boundaries
The suprascapular nerve nerve passes through the notch on its course over the scapula to 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
notchnotch, and it is located inthethe middle third of the superior border - type III: there is a 'U' shape
toto the suprascapularnotchnotch - type IV: similar to type II, but very small; the
suprascapularsuprascapular nerve often passes through agroove next togroove 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
isis completely ossified
