134 tibial shaft fractures managed with the Dynamic Axial Fixator

Abstract

We have reviewed the results of 134 tibial shaft fractures treated with the Dynamic Axial Fixator. In 86 closed fractures, the average union time was 4 months. 76 fractures had united by 5 months; delayed union occurred in 7 cases. 3 closed fractures failed to unite. In 48 open fractures, the union time was related to the severity of soft tissue trauma. The average union time was 5 months for grade II and 6 months for grade III open fractures. 33 open fractures had united by 5 months and delayed union occurred in 11 fractures. 4 open fractures failed to unite. The commonest complication was minor pin site infection, which was seen in 34 percent. These responded rapidly to treatment and external fixation continued. Major pin site infections were uncommon (5 percent) and none led to any serious sequelae. We have found the Dynamic Axial Fixator a safe and reliable device for treating fractures of the tibial shaft.
