Distal humerus fractures - supracondylar fracture

  • The most common humerus fracture. 60% of pediatric elbow injuries are supracondylar fractures.
  • Results from hyperextension secondary to a fall on an outstretched extremity.
  • Classically the distal fragment is posteriorly angulated.
  • These are usually easy to recognize, especially on lateral and oblique radiographic views. Hairline, greenstick or torus fractures can be more difficult to see.
  • Fat pads are almost always elevated, however they may be obliterated due to edema in the surrounding tissues. This fracture should be strongly suspected in the setting of abnormal fat pads.
