Objective: To determine the effectiveness and the safety of the Taylor spatial frame in treatment of intermediate or distal tibiofibula fractures. Methods: The clinical data of 74 patients with intermediate or distal tibiofibular fractures treated between January 2015 and January 2017 were retrospectively analyzed. According to fixation methods, they were divided into internal fixation group (26 cases) and external fixation group (48 cases). There was no significant difference in the age, gender, cause of injury, type of fracture, time from injury to operation between 2 groups ( P>0.05). The intraoperative blood loss, fracture healing time, fixator removal time, and complications were recorded and compared. The final function evaluation criteria of Johner-Wruhs humeral shaft fracture were used to evaluate the function of the affected limb. The lower limb force line recovery after operation was evaluated according to the standard evaluation of LUO Congfeng et al. Results: Both groups were followed up 6-22 months (median, 14 months). All patients obtained the fracture healing. The intraoperative blood loss, fracture healing time, and fixator removal time were significantly higher in the internal fixation group than those in the external fixation group ( P<0.05). There were 1 case of plate exposure, 1 case of delayed fracture healing, and 1 case of plate fracture in the internal fixation group; and there were 2 cases of delayed fracture healing and 4 cases of soft tissue defect in the external fixation group; no significant difference was found in the incidence of complications between 2 groups ( χ2=0.015, P=0.904). The function of the affected limb was evaluated by Johner-Wruhs standard at 10 months after operation, the results was excellent in 19 cases, good in 5 cases, and fair in 2 cases in the internal fixation group, with an excellent and good rate of 92.3%; the results was excellent in 42 cases, good in 3 cases, and fair in 2 cases in the external fixation group, with an excellent and good rate of 95.7%; showing no significant difference between 2 groups ( χ2=0.392, P=0.531). The lower limb force line recovery after operation was evaluated according to the standard evaluation of LUO Congfeng et al.at 4 months after operation, the results was excellent in 24 cases, fair in 1 case, poor in 1 case in the internal fixation group, with an excellent and good rate of 92.3%; the results was excellent in 46 cases, fair in 1 case, poor in 1 case in the external fixation group, with an excellent and good rate of 95.8%; showing no significant difference between 2 groups ( χ2=0.520, P=0.471). Conclusion: The use of Taylor spatial frame in the treatment of the intermediate or distal tibiofibular fractures can obviously reduce the healing time and complications than the internal fixation of the plate. It can reduce the fracture treatment cycle and is beneficial to the fracture healing and limb function recovery, which is relatively safe and reliable.
