One stage internal fixation with posterior transarticular screws and anterior plating for treatment of lower cervical spine fractures and dislocations

Abstract

Objective To evaluate the effects of one stage internal fixation with posterior transartitular screws and anterior plating for the treatment of lower cervical spine fractures and dislocations.Methods From October 2005 to May 2007, 12 patients with fractures and dislocations of lower cervical spine were treated by one stage anterior-posterior internal fixation. Posterior transarticular screw fixation combined with anterior decompression and bone graft and anterior plating were applied for only dislocations.Anterior decompression and bone graft and anterior plating combined with posterior transarticular screw fixation were applied for the fractures and dislocations. The zygapophysial joints were fused. Results All patients were followed up for 6 to 21 (average, 14. 8) months. No loosening of the transarticular screw or nerve-vessel complication was found. Intervertebral and zygapophysial joints all got bony healing. Conclusion One stage internal fixation with posterior transarticular screws and anterior plating is an ideal method of treating lower cervical fractures and dislocations, having the advantages of simple and safe procedures, reliable fixation and a high rate of bone fusion.
