Introduction: the suprascapular notch (SSN) lies on the superior border of scapula, close to the root of coracoid process. The suprascapular nerve passes through the notch, below superior transverse scapular ligament. The objective of the present study was to analyze the main morphological aspects of SSN in scapulae of Northeast Brazil. Material and Methods: a total of 97 adult unpaired scapulae of unknown age and sex were randomly selected. The shape of SSN was determined by direct inspection and the vertical and transverse diameters of the SSN were measured. The type of SSN was determined by using the classification of Natsis et al. (2007) and Iqbal et al. (2010). The results were recorded and statistically analyzed. Results: in the studied scapulae, the SSN was revealed in 70.10%, absent in 29.90% and none of scapulae has bony foramen. Considering Natsis et al., type II SSN was the most common finding on 62.88% scapulae, followed by type I SSN with 29.90% and type III with 7.22%. Types IV and V were not found. According Iqbal et al., only 68 scapulae were macroscopically analyzed, 58.82% were J-shaped and 41.18% were U-shaped. There was not any V-shaped scapula found. The SSN had a longest transverse diameter (type II) in 62.88% and had a longest vertical diameter (type III) in 7.22%. Conclusion: knowledge of the anatomical variations of the SSN is useful for anatomists, orthopedic surgeons, radiologists and neurosurgeons for a better diagnosis and management of the entrapment syndrome.
