Suksathien R Background: The tibial shaft is one of the most common sites of open fracture. External fixators emerged as the treatment ofchoice for high energy open tibial fractures because they were easy to apply, allow sufficient access for wound care andprovide sufficient mechanical fixation for patient mobilization and bone healing. Based on the advantages of dynamization inincreased union rate and the simplicity of monolateral frame, a new design dynamic external fixator system was developed fordefinite treatment in open tibial fracture.
Objective: To evaluate the clinical results of open tibial fractures treated with a new design dynamic external fixator systemuntil healing.
Material and Method: The case series of 60 patients with open tibial fracture treated with the new design dynamic externalfixator system for acute and definitive-treatment frame between 2005 and 2009. According to the system of Gustilo andAnderson, 14 fractures were classified as type II, 43 as type IIIA, and three as type IIIB. Partial weight bearing with crutcheswas instructed when tolerable for dynamization. When there were evidences of fracture healing in both clinical and radiographic,external fixator was removed.
Results: All fractures united. The median union time was 12 weeks (range, 10-15) in type II, 16 weeks (range, 10-24) in typeIIIA, and 20 weeks (range, 20-21) in type IIIB. Iliac bone grafting was performed in six cases at a mean time of 3.8 weeks toenhance bone union. Seven cases (12%) developed pintract infections. No deep infection was found in the present study.Ninety-five percent of fractures united with less than 10 degrees angulation in any plane. No instrument failure was found. Theexternal fixator frame could be reused.
Conclusion: The new design dynamic external fixator system successfully treated open tibial fractures with a good result andlow complication rate. It is simple, safe, and easy to use.
