title: Open tibial fractures treated with the Ex-fi-re external fixation system.
abstract: Fifty open tibial fractures were treated with the Ex-fi-re external fixation system from 1987 to 1994. According to the Gustilo and Anderson classification, there were 12 Grade I, 14 Grade II, 10 Grade IIIA, 13 Grade IIIB, and 1 Grade IIIC injuries. Eight fractures were segmental. The average patient patient age was 39 years (range, 16-85 years). With the reduction unit of the system, displaced tibial fractures could be reduced by the functions of the device in contrast to the manual reductions needed with other unilateral devices. Compression could be applied even to oblique fractures. The reductions were performed by this unit in all cases and were classified as exact in 28 of 41 cases. Exact reduction was defined as a reduction in which there was no more than 2 mm of translational displacement. The 8 segmental fractures were not classified according to reduction. Forty-three fractures healed with no secondary procedure. Three secondary bone graftings, 4 fibulotomies, and 3 renamed intramedullary fixations were performed in 6 patients. Thirty-two skin grafts were performed. There was 1 fracture site infection, and 1 curettage and 1 sequestrectomy were performed after union. At 1 year followup there were no signs of infection. Median time to union was 20 weeks, and median time to full unprotected weightbearing was 22 weeks. Fractures with an exact reduction had a median time of union of 19 weeks, compared with a median of 31 weeks in reductions with greater than 2 mm translational displacement. The exact reduction and translational compression applied in oblique fractures appeared to contribute to early consolidation.
