Shoulder pain is the common cause for the compromised quality of life of the individuals and is due to shoulder impingement syndrome (SIS). A variant acromial morphology and consequent subacromial space reduction is deliberated as the chief basis of subacromial impingement. There are four types of acromion process. Type 1 - flat shaped acromion process, Type 2 – curve shaped acromion process, Type 3 – hook shaped acromion process, Type 4 - convex or upturned acromion process. Type 2 – curved acromion process is most common. Rotator cuff diseases are associated with anatomical variations in the morphology of the acromion process. The aim of the study was to understand the variations of the acromion process, and note its clinical importance so as to help clinicians dealing with rotator cuff diseases.
