Objective: To explore the clinical effect of modified dual plating in the treatment of Schazker IV, V, VI type of complex tibial plateau fractures. Methods: From April 2012 to December 2013, a total of 42 cases with complex tibial plateau fractures were treated using a modified dual plating method in our hospital, they (modified group) were followed up for 1 year, and were compared with 33 cases of complex tibial plateau fractures patients who admitted to our hospital from 2009 to 2011 (ordinary group, used conventional double plates therapy surgery). Results: Improved operation time of modified group was 176.3±23.4 min, blood loss was 225.4±81.3 mL, which were higher than ordinary group (P<0.05). Improved load time of modified group was 19.8±5.8 months, fractures healing time was 3.6±0.8 months, which were significantly shorter than the ordinary group (P<0.05). TPA and PA angle of two groups were compared in 3 d, 3 months after surgery and at the end of the follow-up, the difference of two groups was not statistically significant (P>0.05). Patients' improved flexion, extension in modified group are better than ordinary groups in 3 and 6 months after surgery and last follow-up, the difference was statistically significant (P<0.05). Excellent knee function improved rate of patients in modified group was 95.24%, wihch was higher than that of ordinary group (75.76%) (P<0.05). Conclusion: Although, compared with single plate fixation of tibial plateau fractures, the prolonged operation time and intraoperative bleeding volume increased in dual plating for Schazker IV, V, VI type complex patients. The reduction effect was better and fracture healing time, weight-bearing time were shortened. Patients can do functional exercise earlier, which is conducive to promoting recovery knee joint function of patients.
