Morphological and Morphometric study of suprascapular notch

Abstract

Variation in the morphology of suprascapular notch is associated with suprascapular nerve entrapment neuropathy. So, the knowledge about different shapes of suprascapular notch is important for clinicians in understanding the source of the entrapment syndrome. The Shapes of suprascapular notch are of five in types - Deep U Shaped, shallow U Shaped, J Shaped, V Shaped & indented shaped. Deep U shape is most common & Indented is least common type of suprascapular notch. Suprascapular notch is semicircular in shape, situated in the superior border of the scapula just below the base of the coracoid process. Suprascapular notch is converted to the foramen by the attachment of the suprascapular ligament. Suprascapular vessels passes above the ligament & Suprascapular nerve passes below the ligament. In present study morphological data were obtained and classify the suprascapular notch according to their shape. Present study was conducted on 70 dry human scapulae of both sides with unknown age & sex. This study was conducted in the Department of Anatomy, Hind Institute of Medical Sciences, Barabanki. In the Present study Anatomical variation were found in suprascapular notch which included shape, partial & complete ossification of superior transverse ligament.
