ABSTRACT

Introduction: The Scapula is a large, flat, triangular bone which lies on the posterolateral aspect of the chest wall. The Suprascapular notch is a depression on the superior border of the scapula which gives passage to Suprascapular nerve. Anatomical variations of the shape and size of notch is useful as it is the common site of Suprascapular nerve entrapment syndrome. Materials and Methods: The present study was carried out on 60 adult dry human Scapulae. Different shapes of Suprascapular notch was observed, then vertical and transverse dimensions of the notch were measured.

Results and Conclusion : Based on Rengachary classification, type III notch was found to be most common. Suprascapular foramen was observed in 5 Scapulae. The mean vertical and transverse diameters were measured as 6.43mm and 9.81mm respectively. The study of morphology and morphometry of Suprascapular notch helps to correlate Suprascapular nerve entrapment with specific type of notch.

Key words: Suprascapular notch, Suprascapular foramen, Suprascapular nerve entrapment.
