Curative Effect Comparison Of Distal Radius Fractures Type C: Volar Locking Plate Versus External Fixation And Supplementary K-wires Fixation

Objective:Comparison curative effect of two kinds operation modes of distal radius fractures type C(complex joint fracture of AO/ASIF classification): volar lockingplate versus external fixation and supplementary K-wires fixation. Methods:Patients visit Shanxi Medical University Hospital Second Hospital because of distal radius fractures type C are selected, from 2012 January to 2014 July. Expect 3 patients lost to follow-up. Total of 54 patients, 37 cases were treated with volar locking plate, and others were treated with external fixation and supplementary K-wires fixation. All 54 patients were guided for regular function exercise with mean duration of 16 months(13~20months). Results:Comparison of X-ray performance: radial incline and inclination there were significant differences(P<0.05),radial height of two groups was no significant differences(P>0.05).Wrist flexion,extension,ulnar deviation, radial deviation,pronation,supination and Gartland-Werley score compared explain two groups had no significant differences(P>0.05). Four patients occurred postoperative complications in group locking plate:two cases of extensor tendon injury,one case of nerve injury and one case of CRPS; Two cases occurred postoperative complications in external fixation group, one case of sympathetic response of bone atrophy, a case of pin tract infection, two groups of patients had no significant differences in the complication rate(χ2=0.01,P=0.92). Conclusion:In the treatment of such fractures, two kinds operation modes both have their advantages and disadvantages, including adapting the special fracture type and postoperative complications, et al,from the statistical results, two kinds of operation mode postoperative imaging is slightly different, two kinds operation modes has no significant difference in the wrist joint function recovery. But from the long-term follow-up results, patients, satisfaction rate of locking plate is higher than the external fixation, because of its stable fixation, little postoperative pain, functional exercise convenient, often become the preferred treatment of such fractures. When surgeons planning the treatment prescription, must individual and specific, the type of fracture, bone and soft tissue situation, the willingness of patients even patients’ economic conditions should be considered.
