The 'hooked' acromion revisited.
Examination was made of 750 scapular dry bone specimens from museum collections and 80 cadaver shoulders. Hooking of the acromion was not found in subjects under the age of 30 years. The hooked configuration developed at later ages in an increasing proportion of subjects as a result of calcification of the acromial attachment of the coracoacromial ligament.
