Background

  • Via forceful internal rotation/adduction (sz, electric shock) or blow to ant shoulder
  • Neurovascular and rotator cuff tears are less common than in ant dislocations

Clinical Features

  • Prominence of posterior shoulder and ant flattening of normal shoulder contour
  • Pt unable to rotate or abduct affected arm

Diagnosis

  • Plain film X-ray
    • Scapular "Y" view shows humeral head in posterior position

Differential Diagnosis

Shoulder and Upper Arm Diagnoses

Traumatic/Acute:

Nontraumatic/Chronic:

Refered pain & non-orthopedic causes:

Management

  • Reduce
    • Traction applied to adducted arm in long axis of humerus
    • Assistant pushes humeral head anteriorly into glenoid fossa
  • Sling and swath

Disposition

  • Discharge after reduction
  • Ortho follow-up
