Use of the Ilizarov apparatus to improve alignment in proximal humeral fractures treated initially by a unilateral external fixator

One of the recommended methods for the management of displaced unstable proximal humeral fractures is the unilateral external fixator. In polytrauma cases this method may be especially useful for the stabilisation of these fractures. However, problems may arise if the fracture is fixed in a malaligned or distracted position. Conversion of the treatment concept to other modalities is difficult because of the problem of pin tract infection. The Ilizarov apparatus provides an useful method in such situations, as it allows distraction, translation and compression without the need for further anaesthesia and additional fixation.
