title: CT and MRI manifestations of luxatio erecta humeri and a review of the literature.
abstract: OBJECTIVE
  We aimed to study luxatio erecta humeri using advanced imaging modalities.
  
  
  METHODS
  Patients with luxatio erecta humeri and a subsequent magnetic resonance imaging (MRI) and/or computed tomography (CT) scan were included in this study.
  
  
  RESULTS
  Among 10 identified cases, we detected 2 rotator cuff, 4 labral, and 2 inferior glenohumeral ligament tears as well as 2 glenohumeral cartilage defects. We observed six comminuted displaced greater tuberosity fractures, four anterior inferior glenoid fractures, and four impaction fractures of humeral head.
  
  
  CONCLUSIONS
  This study provides detailed radiologic findings associated with luxatio erecta humeri using MRI and CT.
