Background

  • Usually due to FOOSH
  • 90% are posterolateral
  • Median and ulnar nerves may be injured
  • "Terrible Triad" injury describes unstable joint consisting of:

Clinical Features

  • Elbow held in 45 degree of flexion; olecranon is prominent posteriorly
  • Swelling may be severe

Differential Diagnosis

Elbow Diagnoses

Radiograph-Positive

Radiograph-Negative

Pediatric

Diagnosis

Lateral view
AP view
  • Imaging
    • Look for associated fractures (especially of coronoid and radial head)
    • Lateral: both ulna and radius are displaced posteriorly
    • AP: lateral or medial displacement with ulna/radius in their normal relationship

Treatment

  • Reduce via longitudinal traction on wrist/forearm w/ downward pressure on forearm
  • Immobilize in long arm posterior mold w/ elbow in slightly less than 90deg flexion

Disposition

  • Obtain emergent consult for irreducible dislocations, nerve or vascular compromise, associated fracture
  • Simple dislocation requires ortho follow up within 1 week
