Introduction: The anatomy of the acromion varies considerably from individual to individual, and certain acromial shapes have been associated with an impingement syndrome. Neer’s theory of impingement was further boosted by Nicholson who stated that a higher incidence of rotator cuff tears was present in patients with Bigliani Type III acromion (Hook Type). Objectives: (1) To study the morphometric features of acromion process of scapula (Type, Tength, Tidth and Thickness). (2) To compare the morphology of acromion process and morphology of scapula with those of previous studies. Materials and Methods: The study includes 60 dry scapulae out of them, 30 are of right and 30 are of left side. Only bones with clear and intact features were used for the study while damaged scapulae were excluded. The bone belongs to mature specimens, but the exact ages and gender of the specimens were not known. Descriptive statistics and correlation were calculated using SPSS 20 version. Results: The mean length, width, and thickness of acromion process of scapulae were 41.4 mm, 24 mm and 8.2 mm respectively. We found Type I and Type II acromion process were more in the Telangana region i.e., 46.66% and 38.34 % respectively. The Type III acromion process were 15%. Conclusion: In the present study we found Type I and Type II acromion processes were more in number in the Telangana Region with a very low incidence of Type III acromion process.
