Multiplanar Analysis of Acromion Morphology

摘要: To more completely describe acromion morphology and its relationship to impingement syndrome, we performed three-dimensional magnetic resonance imaging (N 111) or computed tomography 27) on 132 symptomatic shoulders. The mean patient age was 46.2 years (range, 14 86). Four parameters were evaluated: the angle of anterior slope in midsagittal lateral-sagittal planes, lateral acromial angulation coronal plane, presence absence medial encroachment acromioclavicular joint. Twenty-five asymptomatic, age-matched shoulders used as controls. All data combined because no significant differences existed between two techniques. 19.4° plane 20° plane. In 97 (73%) acromions neutral 35 (27%) downward sloping. Medial present 31 (24%) Age distribution from 2nd 8th decade demonstrated a consi...
