A report of the first 20 cases using a simple external fixator

The results of treatment using a locally-designed external fixator in 20 patients are presented. Open fractures were the main indications for external fixation. Pin tract infection occurred in 8 patients. Only 2 patients had unstable fixation which required removal of the device. One third of patients developed malunion exceeding 15 degrees and two thirds had joint stiffness after conversion to plaster cast. This external fixator is adequate in the treatment of most open fractures of the tibia. However, improved techniques of pin insertion and cast application upon removal of the external fixator may help to reduce the incidence of pin tract infections and malunion.
