Background and Aim: Superior border is shortest border of scapula which is marked by suprascapular notch bridged by transverse suprascapular ligament. Beneath this ligament passes the suprascapular nerve. Narrow notch and Type-VI suprascapular notch are one of the risk factors for suprascapular neuropathy. This study is done to study morphological variation of suprascapular notch. Knowledge of various types of suprascapular notch will help the clinician in early diagnosis and surgical treatment. Materials and Methods: A total of 525 human scapulae were taken to study morphology of suprascapular notch at the Anatomy Department, GMERS Medical College, Vadnagar and at B. J. Medical College, Ahmedabad. Age and sex of scapulae were not established. Digital camera is used to take photos of different suprascapular notch and classified as per Rengachary classification. Results: As per Rengachary classification in our study, of 525 scapulae most common suprascapular notch type is Type-III 47.1%, least common is Type-V 1.9%, and incidence of Type-VI is 8.9%. Conclusion: A study of different types of suprascapular notch can help the physician in screening high risk patient as well as diagnosis and treatment of suprascapular neuropathy disorder.
