Introduction: The suprascapular notch is the major site for suprascapular nerve compression. Objective: To study morphological variations of suprascapular notch in South Karnataka population and to determine posteriosuperior and posterior limits of safe zones for shoulder arthroscopic procedures from posterior approach. Materials and Methods: 100 dried adult human scapulae of unknown sex, obtained from Department of Anatomy, Kodagu Institute of Medical Sciences, Madikeri, Karnataka, India. Information regarding various forms of the suprascapular notch was noted. Results: Suprascapular notch was present in all Scapula. Based on Rengachary classification, most prevalent was Type III (33%) and least was type VI (1%). Superior Transverse Diameter (STD) =12.19±4.83, Mid Transverse Diameter (STD) =8.22±2.98 , Maximum Depth (MD) =8.46±3.35. The mean distance from SSN to Supraglenoid tubercle was 29.82±4.06 and the distance between the medial wall of the spinoglenoid notch and the posterior margin of the glenoid cavity was 15.19±2.64 respectively. Conclusions: Knowing about the morphological variations of suprascapular notch will assist the clinicians in order to understand the concepts of suprascapular nerve entrapment which will help the outcome of the treatment.
