Pediatric Anterior Shoulder Dislocation

  • Etiology: Often related to sports activity
  • Imaging:
    — Document dislocation
    — Hill-Sachs deformity is impaction injury of anteroinferior glenoid on posterolateral humeral head which affects top 2 centimeters of humeral head
    — Bankart lesion is impaction injury of anterior and inferior glenoid
  • DDX:
  • Complications:
    — Hill Sachs deformity is common complication, Bankart lesion is less common complication
  • Treatment: Reduction
  • Clinical: Anterior shoulder dislocation seen 95% of time

Radiology Cases of Anterior Shoulder Dislocation

Radiograph of anterior shoulder dislocation
AP (above) and axillary (below) radiographs of the right shoulder show the right humeral head to be displaced anteriorly and medially in relation to the glenoid fossa.

Radiology Cases of Anterior Shoulder Dislocation With Hills-Sachs Deformity

Radiograph of anterior shoulder dislocation with Hills-Sachs lesion
AP (upper left) and axillary (above right) radiographs of the left shoulder show the left humeral head to be displaced anteriorly and medially in relation to the glenoid fossa. Post-reduction AP radiograph of the left shoulder (below) shows a defect in the posterolateral aspect of the humeral head.
