The Suprascapular Notch: Its Morphology Morphometry And Clinical Significance

ABSTRACT

Introduction: The Scapula is a large, flat, triangular bone which lies on the posterolateral aspect of the chestwall. The Suprascapular notch is a depression on the superior border of the scapula which gives passage toSuprascapular nerve. Anatomical variations of the shape and size of notch is useful as it is the common site ofSuprascapular nerve entrapment syndrome.Materials and Methods: The present study was carried out on 60 adult dry human Scapulae. Different shapes ofSuprascapular 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 measuredas 6.43mm and 9.81mm respectively. The study of morphology and morphometry of Suprascapular notch helpsto correlate Suprascapular nerve entrapment with specific type of notch.
