Abstract: Objective: To explore the feasibility and efficacy of the external fixator for the treatment of type C fracture of distal radius. Methods: 22 cases of C type fracture of distal radius treated in our hospital from March 2012 to March in our hospital were treated with the method of -2014 assisted external fixator for the treatment of patients with distal radius fractures. And the patients were followed up for an average of 12 months. The patients were observed and recorded. Results: X-ray examination showed that 22 patients were cured, the time of removal of the fixed frame was 5-11 months, average 7.1 + 0.3 weeks. After measuring the volar tilt angle and ulnar deviation mean respectively (11.51 + 2.12) degree and (24.32 + 1.75) degree, in the longitudinal axis of the radial average height display (10.84 2.26 +) mm, compared to preoperative were significantly improved (P < 0.05). According to the method proposed by Aro et al. To evaluate the quality of fracture reduction, the results showed that 14 cases were excellent, 5 cases were good, 3 cases were available, the excellent and good rate was 86.3%. According to the criteria proposed by Dienst et al. To evaluate the therapeutic effect, the results showed that 13 cases were excellent, 4 cases were good, 3 cases were available, 2 cases were poor, the excellent and good rate was 90.9%. After 3 weeks of surgery, patients began functional exercises, in this process there are 2 patients with type C3 fractures of the fracture shift, mainly for the palm dip angle. After the implementation of the replacement of the patients with G's needle assisted fixation, after a period of rest after re examination showed all healed, but 1 of them in the Dienst score results show that the difference. Pinhole infection occurred in 1 patients, the dressing was strengthened after the symptoms quickly disappeared. In the course of operation and treatment, there were no iatrogenic injury of nerve and blood vessels in any patient. Conclusion: in the treatment of type C distal radius fractures, the limited Kirschner wire auxiliary fixation method, strengthened the role of can accelerate the cure rate of hoist complication rate of reduction of fracture, knee function recovered satisfactorily, is worthy of clinical application on the stability of fracture reduction.
