MANAGEMENT OF UNSTABLE TIBIAL DIAPHYSEAL FRACTURES BY EXTERNAL FIXATION

A group of 30 patients of unstable tibial diaphyseal fractures were managed using unilateral tubular external fixator. The fixator assembly comprised a double stainless steel hollow rod with universal joints and schanz screws as principal implant. Reduction and controlled distraction or compression were achieved by means of distracter/compressor device. Early dynamization was resorted to. The union rate was 100% with average healing time between 20 weeks for closed unstable fractures and 27 weeks for open Gustilo grade-II fractures. Minor pin tract infections accounted for majority of the complications. The unilateral fixator assembly permits early ambulation in unstable tibial diaphyseal fractures without sacrificing a sound anatomical result.
