Introduction: Suprascapular notch is a depression on the lateral one third of the superior border of the scapula. Suprascapular nerve passes through this notch. The shape of this suprascapular notch can vary among individuals. Various shapes and sizes of the notch and ossified superior transverse scapular ligament can compress the suprascapular nerve leading to entrapment syndromes. Hence the study of morphometry of the notch is important to diagnose and treat such entrapment syndromes.

Materials and Methods: 58 dried human scapulas were used for the study. The morphology of the suprascapular notch was studied. Presence and absence of the notch was observed. Type of notch was assessed based on the its shape according to Rengachery’s classification. The superior transverse diameter, middle transverse diameter, maximum depth of the notch, and the distance between the posterior glenoid rim and the notch was measured.

Results: Type II and type III notches are common in Indian population. Type II notch has larger diameters and greater depth, while type IV has the least diameters and depth. Type V and VI notches are more prone for suprascapular nerve entrapment due to ossification of superior transverse scapular ligament.

Conclusion: Knowledge of different types of notches and its measurements are very helpful in diagnosis and management of cases with shoulder pain due to suprascapular nerve entrapment and also while administering suprascapular nerve blocks for the surgeries involving the shoulder.

Key words:  Suprascapular Nerve, Suprascapular Notch, Superior Transverse Scapular Ligament, Suprascapular Nerve Entrapment Syndromes.
