The use of external fixation in the emergency department: applications, common errors, complications and their treatment.

The use of an external fixator (EF) in the emergency department (ED) or the emergency theatre in the ED is reserved for critically ill patients in a life-saving attempt. Hence, usually only fixation/stabilization of the pelvis, tibia, femur and humerus are performed. All other external fixation methods are not indicated in an ED and thus should be performed in the operating room with a sterile environment.Anterior EF is used in unstable pelvic lesions due to anterior-posterior compression, and in stable pelvic fractures in haemodynamically unstable patients.Patients with multiple trauma should be stabilized quickly with EF.The C-clamp has been designed to be used in the ED to stabilize fractures of the sacrum or alterations of the sacroiliac joint in patients with circulatory instability.Choose a modular EF that allows for the free placement of the pins, is radiolucent and is compatible with magnetic resonance imaging (MRI).Planning the type of framework to be used is crucial.Avoid mistakes in the placement of EF.
