Abstract
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 have analyzed acromion´s morphology in scapulas of Brazilian human skeleton and tried to establish possible morphofunctional correlations to literature data. Materials and Methods: Fifty-seven scapulas from Human Anatomy laboratories of Universidade Federal de Minas Gerais were selected and divided in groups according to acromion´s tip morphology and angle. Results: We observed that distribution of acromial morphology was 5,2% type I (flat), 57,9% type II (curved), 36,9% type III (hooked). Conclusion: Our data is important to compare Brazilian scapula bones to those from various other regions or races and could contribute to demographic studies of shoulder disease probability in Brazilian population.
