Contraindications to the repositioning of fractured or dislocated limbs in the fields.

Supracondylar fractures of the femor or humerus and fractures of the radius, ulna, tibia or fibula, plus crush injuries of the limbs, most likely should not be manipulated in the field because of the potential for traumatizing adjacent nerves, veins and arteries. An emergency splinting system that allows immobilization without repositioning has been developed. Furthermore, fractures in or about the elbow, wrist, knee, or ankle should not be subjected to reduction in the field, unless there are compelling reasons to justify the risk of producing significant additional trauma. Conservative immobilization without repositioning may yield a more positive prognosis for the patient.
