Objective To evaluate the therapeutic effect of modified dual plating and less invasive stabilization system(LISS) in the complex fractures of tibial plateau.Methods One hundred and sixty-eight patients with complex fractures of tibial plateau were divided into two groups by the therapeutic methods,89 patients were in modified dual plating group while 79 patients were in LISS group.The advantages and curative effect of two groups were retrospectively analyzed.Results The excellent and good rate in modified dual plating group was slightly higher than that in LISS group [89.9％ (80/89) vs.86.1％ (68/79)],and there was no significant difference (P ＞ 0.05).No patient occurred deep site infection,severe nerve damage,phlebothrombosis in two groups.In modified dual plating group,the operation time and bleeding volume was (89.2 ± 13.6) min and (188.4 ± 45.6) ml,the hospital stay and healing time was (16.5 ± 1.8) d and (13.3 ±2.1) months.In LISS group,the operation time and bleeding volume was (74.3 ± 12.5) min and (236.5 ±65.5) ml,the hospital stay and healing time was (16.7 ± 2.1) d and (11.4 ± 1.5) months.There was no significant difference (P ＞ 0.05).Conclusion The therapeutic effect of modified dual plating and LISS have no significant difference for complex tibial plateau fractures.
