Morphometry Of Acromion Process Of Human Scapulae

ABSTRACT

Background: The acromion process plays an important role in formation of the shoulder joint and providesstability to the shoulder joint. Acromion process resection is done in case of shoulder impingement syndrome.Materials and Methods: About 100 dry human scapulae were measured for parameters such as length, breadthof acromion process of scapula. The acromio coracoids distance and acromio glenoid distance was measuredusing vernier callipers.Observation It was observed that the curved type of acromion process was the commonest type. Flat type is leastcommon type. The mean length of acromion process on right side is longer significantly than the left side. Thelength of acromion process on right side is significantly longer than the left side. All the other parameters(Breadth of acromion process, Acromio glenoid distance, acromio clavicular distance on right and left side wasnot significant.Conclusion: The present study provides useful data of dimensions of acromion which may help the orthopaediciansduring surgical repair around the shoulder joint. It will of interest to anthropologists when studying about theevolution of the bipedal gate
