Popis: Introduction: The scapulae of human bone bears suprascapular notch and the ligament in it undergoes ossification causing compression of the suprascapular nerve. The degree of ossification of transverse ligament of scapula helps to differentiate it from rotator cuff tear as to prevent muscle wasting and atrophy. Materials and Methods: A sample of 50 dry scapulae bone in the Anatomy department, Annapoorana Medical College & Hospitals, Salem was utilized. Based upon suprascapular notch shape, the scapulae were categorized into six varieties. The parameters such as Superior, Middle and Inferior transverse length, Notch depth was determined thrice by taking measurements with vernier caliper. The results were analysed by software SPSS (IBM) 25 version. Results: The findings revealed, the predominant type was Type III and Type I (24%) and least was Type VI (4%) with complete ossification of STSL. The mean MD in Type IV notch is 6.32±1.19mm where the depth was ultimately reduced compared to Type II, III, V notches. So, the depth of Type IV notch should be kept in mind to predict neuropathy as it may cause nerve compression. Conclusion: The current study helps clinicians be aware about variations in the morphometry of SSN while categorising the notch type causing neuropathy before performing any surgical intervention.
