Background

  • Very stable joint making a dislocation rare; majority of injuries are simple sprains
  • Dislocations usually require severe force (MVC, sports injuries)
  • Anterior dislocations are much more common than posterior
  • Due to both force and anatomic location, damage to the brachial plexus, subclavian, trachea, and esophagus may occur[1]

Clinical Features

Sprain

  • Pain and swelling are localized to the joint

Dislocation

  • Severe pain that is exacerbated by arm motion and lying supine
  • Shoulder appears shortened and rolled forward
  • Anterior dislocation: prominent medial clavicle end is visible/palpable ant to sternum
  • Posterior dislocation: Medial end is less visible and often not palpable

Diagnosis

  • CT
    • Study of choice (plain films may not be diagnostic)
    • Consider IV contrast if concern for injury to mediastinal structures
  • Serendipity view Xray
    • Xray taken at a 40 degree cephalic tilt may be useful if CT unavailable.[2]

Management

  • Symptoms of stridor or shortness of breath, or dysphagia indicate aerodigestive tract injury and require immediate reduction

Sprain

  • Rice, sling, analgesics

Anterior Dislocation

  • May discharged without attempted reduction (no impact on function)
  • Clavicular splinting, ice, analgesics
  • Ortho referral

Posterior Dislocation

  • May be associated with life-threatening injuries:
    • Pneumothorax, compression/laceration of surrounding great vessels, trachea, or esophagus
  • Consult ortho for closed reduction (ideally performed in the OR or under Procedural Sedation)
  • A towel clip could be used to grasp the medial clavicle, pulling anteriorly until reduction is complete
  • May be observed afterwards due to severity of trauma and risk for vascular injury[3]
