Right anterior shoulder dislocation. No evidence of bony Bankart lesion or Hill-Sachs deformity. No acute fracture. Small effusion within the right glenoid fossa.
Incidental enchondroma in the left proximal humerus.
Shoulder dislocations are common, with ~95% of these being of the anterior dislocation type. They occur most commonly from falls at home (in the elderly) or during sporting activities (in younger age groups).
CT imaging of acute dislocations are uncommon as physical exam or plain film is usually enough to diagnose these, and the shoulder is usually reduced prior to any further imaging. CT can be useful in elucidating bony injuries post-reduction.
In this case we can see that the right humeral head has dislocated anteriorly, and now lies inferior and medial to the coracoid process. No gross bony injury, such as a bony Bankart lesion or Hill-Sachs deformity is present. The patient's shoulder was relocated without issue.
