[The dynamization of external fixation for treatment of open tibia and fibula fractures].

Objective: To evaluate the effects of dynamization of external fixation on open tibia and fibula fracture union. Methods: >0.05). The removal time of external fixator in group B was evaluated by fracture healing time, X-ray film, and doctor's experience. In group A, the growth of callus was examined based on X-ray film at 12 weeks after operation; the axial mechanical load ratio was tested, and dynamic loading was carried out when the axial mechanical load ratio was 5%-10%. The using time of external fixator, fracture healing time, and incidence of complications were compared between 2 groups. Results: =1.000). Conclusion: Dynamization of external fixation can promote union of open tibia and fibula fractures with a high security.
