Abstract

Background: The Suprascapular Notch (SSN) is located at the superior edge of the scapula. The information of variations in shapes and classification can be obliging to surgeons to correlate the suprascapular nerve entrapment with a specific type of notch. The aim of this study is to document the occurrence of morphological variations in shape of suprascapular notch in dry scapulae which belongs to population of Gujarat & evaluate it with prevalence among various races of world to know its clinical significance. Methods: Total two hundred dry and intact adult human scapulae were studied of mixed sex of Indian origin derived from various medical colleges of Gujarat. All Measurements were taken by classical osteometry with the help of electronic calipers with the accuracy of 0.01mm in millimetres. Results and Interpretation: The most common type of SSN observed was Type 2, a notch that was longest in its transverse diameter. The least common type was Type 4. Type 5 SSN was absent. The most common shape was ‘J’ and least common was ‘V’. Partial and complete ossification was also noted. Conclusion: Knowledge of anatomical variations of suprascapular notch is better for understanding location and source of entrapment syndrome. Since, the present study is performed with a limited number of dry scapulae, so there is need of further clinical, radiological and cadaveric studies.
