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

To evaluate the effects of dynamization of external fixation on open tibia and fibula fracture union. The clinical data of 26 cases of open tibia and fibula fractures treated by external fixation were retrospectively analysed. According to different postoperative treatment methods, the patients were divided into elastic dynamic group (group A, =13) and constant elastic fixation group (group B, =13). There was no significant difference in gender, age, and fracture type between 2 groups ( >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. All patients were followed up 4-13 months, with an av
