Closed tibial pilon fractures treated with external fixationFracture fermée du pilon tibial traitée par fixateur externe

Fractures of tibial pilon are due to a high energy trauma. Associated skin complications are frequent as those of surgery of this pattern. Thus we performed external fixation as treatment for these fractures. Authors report a retrospective study of 17 closed fracture of tibial pilon, type C of Ruedi and Heim classification, treated by osteotaxis using external fixation of Hoffman with osteosynthesis of fibula by screwed plate. Our patients are of a mean age of 34 years with 11 men and 6 women. The right side was most frequently involved (12 patients). Skin injuries as phlyctena were seen in 6 patients. Delay of treatment did not exceed 72 h. We performed a closed reduction of the fracture of tibial pilon after internal fixation of fibula by screwed plate. Results were assessed after 24 months of study. Track pins infection was noted in three cases. Reduction was usually good, despite one case of recurvatum, one case of valgus, one case of Sudeck’s atrophy, three cases of arthritis have been noticed. Mobility decreased at about 30%. External fixation is a real alternative solution for treatment of these fractures for which osteosynthesis is not suitable. It allows us to avoid skin complications despite mobility decreasing.
