External fixation of the tibia. Basic concepts and prospective evaluation

External fixation of fractures of the leg may give uneven results and a high rate of complications. We postulate that three basic principles can govern the optimal use of these devices. The external fixation frame should avoid damage to vital anatomical structures, it should allow access to the injured area and it should meet the mechanical demands of the patient and the injury. From 1978 to 1981 these principles were evaluated prospectively in 75 consecutive cases of complex tibial injury treated with an external frame. Most were open fractures. The study confirmed that the principles were safe and effective; they have general application and do not depend on the use of a particular frame or device. By following them we have eliminated the majority of complications seen after traditional methods of external fixation.
