title: Imaging signs of posterior glenohumeral instability.
abstract: OBJECTIVE
  The purpose of this article is to review mechanisms of injury leading to posterior glenohumeral instability and the correlated imaging findings on CT and MRI.
  
  
  CONCLUSIONS
  In patients with suspected posterior glenohumeral instability, imaging of the affected shoulder can show abnormalities of the bone, labrum, and joint capsule. Accurate detection and characterization of these lesions aid in both diagnosis and management.
