ABSTRACT Introduction: Various studies have reported the relative association of morphology of acromion and rotator cuff diseases. There is a strong genetic control over the variability in shape of the acromion. Considering this variability and the clinical relevance, the present study was aimed to document the quantitative measurements in South Indian acromions. Study objectives were to estimate the qualitative and quantitative parameters of the acromion among South Indian adult scapulae. Material and Methods: An observational study was performed on acromion process of 130 scapulae. The acromion dimensions (maximum length, maximum width, maximum thickness, acromio-coracoid distance and acromio-glenoid distance) were measured using Vernier digital caliper. The prevalence of the type of acromion and the type of inferior surface of anterior third of acromion were also calculated. Results: The mean acromial length was 40.97 ± 5.25mm, mean acromial width was 29.98 ± 4.44 mm, mean acromial thickness was 7.42 ± 1.31 mm, acromio-coracoid distance was 29.83 ± 4.74 mm and acromio-glenoid distance was 26.18 ± 3.14 mm. There was found to be significant difference in width, acromio-coracoid distance and acromio-glenoid distance between right and left sides. The prevalence of type of acromion was found to be: type I- 9.23%, type II- 89.23% and type III- 1.54%. Conclusion: The morphometric data of acromion process and the types of acromion may be helpful for the orthopedicians during surgical repair around the shoulder joint.
