ABSTRACT:

Background: Due to its many variations, scapula became one of the most interesting bones of human skeleton. The acromion process projects forwards almost perpendicularly from the lateral end of spine of scapula. The acromion process is associated with a variety of ailments in the shoulder joint. As morphometry of the Acromion process of the scapula is an important factor implicated in impingement syndrome of the shoulder joint, the purpose of present study is to record the morphometric values of the acromion process and its morphological features in South Indian population.

Methodology: One hundred and sixty-four dry adult scapulae of unknown age and sex belonging to South Indian population were studied. The acromial length, acromial width, acromio-coracoid distance and acromio-glenoid distance were measured using Vernier caliper and recorded in millimeters (mm). Different types of acromion process are also noted.

Results: The mean acromial length was 42.47 ± 4.68 mm, the mean acromial width was 26.57 ± 3.28 mm. The mean acromio-coracoid distance was 34.05 ± 4.94 mm. The average acromio-glenoid distance was 30.05 ± 4.08 mm. The three types of acromion were observed as type – I flat was seen in 37.1%, type II curved in 47.5% and type III hooked in 15.2%.

Conclusion: Knowledge of the morphometric data of acromion process may not only help the surgeons during surgical repair around the shoulder joint but also may be of interest to the anthropologists while studying the evolution of bipedal gait.

Key words: Acromion, Morphometry, Shoulder, Scapula.
