Abstract:Objective To compare the therapeutic effect and safety of limited internal fixation combined with external fixation and bilateral inside-fixed steel for complex tibial plateau fractures. Methods Sixty-eight patients with complex tibial plateau fractures, who had surgery in our hospital from August 2013 to August 2016, were selected and randomly divided into experimental group (36 cases) and control group (32 cases). The patients in the experimental group were treated with limited internal fixation combined with external fixation and those in the control group were given internal fixation with bilateral steel plates. The operative situation, fracture healing time, complications and knee functional scores were observed. Results There were statistical differences in the operation time, intraoperative blood loss, fracture healing time and knee functional scores between the two groups (P < 0.05).However, as to postoperative complications only infective of operation incision was significantly different between the two groups (P > 0.05). Conclusions Compared with the bilateral inside-fixed steel, limited internal fixation combined with external fixation is safe and effective in the treatment of complex tibial plateau fractures, and there are fewer complications.
