Abstract: The supra scapular notch is situated in the lateral part of the superior border of the scapula, adjacent to the base of the coracoid process. The notch is converted into a foramen by the transverse scapular ligament and it serves as a passage for the suprascapular nerve. Suprascapular nerve entrapment is an acquired neuropathy which is secondary to the compression of the nerve, in the bony suprascapular notch. The suprascapular notch is an important landmark of the suprascapular nerve during arthroscopic shoulder operations. The present study was planned as the literature revealed that only very little data was available on the morphology of the suprascapular notch, particularly in the north Indian population & compare it with incidence among various races of world to know its clinical significance. The present study was planned in Department of Anatomy, Anugrah Narayan Magadh Medical College, Gaya, Bihar, India from Jan 2016 July 2016. Total 50 human dried scapulae received in the department were evaluated in the present study. Each scapula is observed carefully for different shapes of suprascapular notches on superior border of scapula. Approval of the institutional ethical committee was taken prior to conduct of this study. A study on the morphology of the suprascapular notch is useful, as the notch is the common site of nerve compression. The type of notch may be the cause of a nerve entrapment. One of the site of compression of suprascapular nerve is the suprascapular notch. Since the suprascapular notch is the common site of nerve entrapment, the knowledge about morphometric variation of suprascapular notch is essential for clinician in making a proper diagnosis and for planning the most suitable surgical intervention.
