Abstract
For some years, external fixators, in which screws or pins project from the fixator (which, as its name suggests, is outside the limb) into parts of a fractured bone to hold them firmly together, have been used successfully to hold fractures in long bones of the arms and legs, and also fractures of the pelvis and jaw [1]. In many instances, this method has advantages compared with Plaster-of-Paris or internal fixation with metal plates or rods.
