Background: Suprascapular notch is present along the superior border of the scapula close to the lateral angle, which is converted into a Suprascapular foramen by the transverse Suprascapular ligament. Normally the Suprascapular nerve and vein pass through the foramen below the ligament, while the Suprascapular artery runs above the ligament. Suprascapular nerve entrapment is an interesting clinical condition which is widely involved in this area. Aim of the study: To find out the presence of Suprascapular artery passing along with the Suprascapular nerve and vein within the foramen and any pathology associated with it. Materials and Methods: The proposed study is carried out in the Department of Anatomy, Karpagam Faculty of Medical Sciences and Research, Coimbatore, where 51 well embalmed cadavers of both the sexes and various age groups was utilised. Results: Out of 51 cadavers dissected, we found Suprascapular artery was found passing along with the Suprascapular nerve and vein in 2 of the cadavers, of which one each is found in a male and a female cadaver with an incidence of 3.92%. Conclusion: Studies done earlier pointed out the importance of Suprascapular nerve entrapment, the various causes and predisposing factors responsible for it ,and a knowledge of safe zone around the shoulder region should be known well to the operating surgeon and the available imaging techniques should be utilised by the radiologists in order to avoid the complications while dealing with the Suprascapular nerve entrapment. KEY WORDS: Cadaver, Suprascapular foramen, Suprascapular artery, Nerve entrapment, Transverse Suprascapular ligament.
