Abstract
This paper describes the outcome of type III pilon fractures of the distal tibia treated primarily with an Ilizarov ring fixator.
Only patients with an intra-articular fracture of the tibial plafond on plainradiographs that corresponded to type III pattern with the system of Rfiedi andAllgower were included.
There were thirteen patients with a mean age of 45 (range 29–65), twelve males and one female. The mechanism of injury in all the patients was high-speed road traffic accident.
Operative fixation consisted of fracture reduction and stabilisation using the llizarov circular frame external fixator and olive tipped wires. Further insult to the already damaged soft tissues was avoided.
Bony union was achieved in all cases. Treatment in the frame lasted between 3 and 10 months (average 6. 3 months). Neither deep infection nor soft tissue complications occurred.
Outcome measurements included the Olerud ankle score, modified Ovadia and Beals radiological criteria, and the SF-36 Health Questionnaire.
Wound and deep infections were successfully avoided and bony union was achieved in all our patients. This compares well with other fixation techniques. The use of the llizarov circular frame external fixator without any additional internal reduction or fixation procedures is a definite option for the treatment of these high-energy injuries.
