ABSTRACT
Suprascapular notch is the site where the suprascapular nerve traverses the upper border of the scapulae under the superior transverse scapular ligament (STSL). The anterior coracoscapular ligament runs in the suprascapular notch, below the STSL. Narrowed bony foramen by complete ossification of these ligaments may be one of the predisposing factors for suprascapular nerve compression. We report the two cases of the bony suprascapular foramen, scapula with complete suprascapular foramen and scapula with suprascapular foramen with the notch. The aim of our case report is to provide knowledge on the variations along the course of suprascapular nerve which is essential to understanding the source of the entrapment syndrome. A thorough knowledge of anatomical variations in the suprascapular region and ossification of suprascapular ligament is important for anatomists, orthopedicians, radiologists, and neurosurgeons to obtain a safe zone which would be useful to avoid iatrogenic nerve lesion and for better diagnosis and management of the nerve entrapment syndrome.
KEY WORDS
