Disclosures

  • » A flexion supracondylar fracture of the humerus is an uncommon fracture in children and accounts for only 1% to 10% of all supracondylar fractures.
  • » The injury is caused by a direct fall on the point of the elbow, causing hyperflexion at the elbow, rather than by a fall on an outstretched hand, which is the mechanism in an extension-type fracture.
  • » The ulnar nerve is at higher risk of injury in this fracture by the spike of the proximal fragment or by entrapment in the callus.
  • » This fracture is inherently unstable, leading to difficulty in maintaining reduction intraoperatively and difficult Kirschner wiring in the extension position in which the reduction is achieved.
  • » Kirschner wiring can be done in a flexed position of the elbow by utilizing a push-pull method, a temporary transolecranon pin, or a Kirschner wire as a joystick in the distal fragment to achieve and maintain reduction before the insertion of the final pins.
