The suprascapular notch (SSN) plays a crucial role in transmitting the suprascapular nerve, which is susceptible to compression along its course, particularly at the SSN and spinoglenoid notch. Understanding anatomical variations in the SSN is essential, as these variations may predispose individuals to suprascapular nerve entrapment, resulting in pain, muscle weakness, and functional disability. This study examined 90 dry human scapulae to evaluate morphological differences in the SSN and their potential role in nerve compression syndromes. Variations were documented through direct observation and photographic analysis, and categorized based on established morphological classifications. The majority of scapulae demonstrated a U-shaped notch, while other shapes, including V-shaped, J-shaped, and complete ossification of the superior transverse scapular ligament forming a foramen, were noted. Anatomical variations of the SSN are clinically significant, influencing diagnosis, imaging interpretation, and surgical planning. Awareness of these variations helps clinicians, radiologists, and orthopedic surgeons prevent iatrogenic injury and improve treatment outcomes in cases involving shoulder pain or nerve compression. Our findings highlight the necessity of recognizing diverse SSN configurations for accurate assessment of suprascapular neuropathies and for guiding safe surgical interventions.
