What is a shoulder notch?
The notch is formed lateral to the point which the spine extrudes from the scapula, with the spinoglenoid ligament (also known as the inferior transverse scapular ligament) forming a foramen by passing from the lateral aspect of the scapular spine to the posterior part of the glenoid.
