Case Discussion

Anatomic variations in the shape of suprascapular notch are divided into 5 types:

Type I (no notch): A wide depression of the superior border of the scapula.

Type II: A wide blunted V-shape notch.

Type III: A slightly deeper notch with almost parallel lateral margins "U-shape" notch

Type IV: A small notch ‘V’shaped.

Type V: The medial part of the ligament is partially ossified forming a notch with a small diameter along the superior border of the scapula.

Type VI: The ligament was completely ossified forming a bony foramen located inferomedial to the base of the coracoid process.

Suprascapular nerve entrapment may be due to the variable morphology of the suprascapular notch.
