Using external fixator in treatment of distal radial intraarticular fractures

Introduction: Fractures of distal radius are common in adulthood and treatment of these fractures especially displaced intraarticulars are controversial. External fixation is one of treatments for these fractures. This study was designed to evaluate the results of distal radial intraarticular fractures treatment with external fixator (transfixation). Materials and Methods: This is a study with no control in which 26 patients (30 fractures) with distal radial fractures (universal type IV) where selected by convenience method. Closed reduction and external fixator application for 6 weeks was performed in all patients. Patients were followed for one year. Results: There were 26 patients (4 bilateral cases) including 24 males and 2 females. Their average age was 28± 5 years. Average follow up time was 8 months (6 to 20 months). Clinical and radiographic union occurred in all patients. At the last follow up four patients had pain with vigorous activity (13%). Limitation of motion was severe in one patient (3%) and mild in two patients (6%). Average radial shortening was 4 millimeters and average volar tilt and unlar inclination were 5.4 ± 6.6° and 12.5 ± 4.5° respectively. Conclusion:Considering our clinical and radiological results it seems that external fixator is a good method for treatment of displaced intraarticular distal radial fractures.
