Anatomical variations of acromions in brazilian adult's scapulas

Introduction: According to morphology, acromion can be classified into three types: I (flat), II (curved),and III (hooked) and its characteristics are related to age and rotator cuff pathology. Here we haveanalyzed acromion s morphology in scapulas of Brazilian human skeleton and tried to establish possiblemorphofunctional correlations to literature data.Materials and Methods:Fifty-seven scapulas from HumanAnatomy laboratories of Universidade Federal de Minas Gerais were selected and divided in groups accordingto acromion s tip morphology and angle.Results:We observed that distribution of acromial morphologywas 5,2% type I (flat), 57,9% type II (curved), 36,9% type III (hooked).Conclusion:Our data is importantto compare Brazilian scapula bones to those from various other regions or races and could contribute todemographic studies of shoulder disease probability in Brazilian population.
