Background and Aim: The Suprascapular notch is present at the anterolateral end of the superior border of scapula medial to the root of the coracoid process. The notch is bridged by the superior transverse scapular ligament which is attached laterally to the root of the coracoid process and converts the notch into the foramen. This

foramen transmits the suprascapular nerve (SSNr) to the fossa. This study was focused on different types of the suprascapular notch (SSN) and its combination of the anomalous superior transverse scapular ligament (STSL) was considered as a risk factor for Suprascapular nerve entrapment. Materials and Methods: This study was done

in 100 human dry scapulae. The shapes of the SSN, partially or completely ossified STSL were noted and the maximum depth, superior and middle transverse diameters of suprascapular notches was measured. The data analysis of the notches was recorded and correlated with previous studies. Results: The shape of the SSN was observed and classified into six types. The most common type of notches ”U” shaped and less common type was small “V” shaped. The partially or completely ossified STSL was also observed in this study. Conclusion: The anatomical knowledge of various types of SSN and the prevalence of ossified STSL is important for clinicians for giving suprascapular nerve block. The Knowledge of anatomical variations of SSN helps the orthopedic surgeon to diagnose the cause for painful syndromes of shoulder and the early management which helpsforgood functional recovery.
