Shoulder Case 3 Additional Images

This is a post reduction xray after an anterior shoulder dislocation demonstrating a Hill-Sachs deformity, which is a compression fracture at the posterolateral head of the humerus due to impingement against anterior rim of glenoid fossa when the humeral head dislocates.

This is another patient with a glenohumeral dislocation demonstrating a Hill-Sachs deformity (blue arrow) and a Bankart lesion (red arrow). A Bankart lesion is an avulsion of anteroinferior glenoid labrum where the inferior glenohumeral ligament attaches. Both lesions indicate shoulder instability and a higher risk for recurrent dislocation.

This patient presented after falling on his fully abducted shoulder and is in intense pain with the arm locked in abduction. The patient has an inferior glenohumeral dislocation, or Luxatio Erecta, resulting from a hyperabduction injury. Classically the patient presents with the arm locked overhead and rested on top of their head with the shoulder in 110-160 degrees of abduction. Reduction should be performed quickly via traction/counter traction.
