| 【Abstract】 Objectives: To observe the reliability of the self-design thread-tooth arc-track screw plate system(TASPS) in minimally invasive lumbar fusion. Methods: From February 2008 to February 2011, 132 cases with lumbar instability were treated by minimally invasive lumbar fusion. All cases were divided into observation group and control group. The observation group underwent self-designed TASPS, while the control group underwent pedicle screw fixation system. The data including operation time, instrumentation time, blood loss, VAS score, ODI and improvement rate were collected and investigated at 1 week, 3 months and 1 year postoperatively. The disc height at 3 months and 1 year and the fusion rate at 1 year were also reviewed. Results: All patients underwent minimally invasive operation, all skin incisions healed without any complication. The observation group had shorter operation and instrumentation time than control group, and less blood loss. The VAS scores of two groups at 1 week, 3 months and 1 year after operation were significantly lower than the preoperative ones. ODI score improved after 3 months, which showed significant difference than that before operation, and further improvement at 1 year after operation was noted, which showed significant difference compared with that at 3 months after operation. After 1 year, the improvement rate in observation group was (79.46±6.34)％, while (76.73±4.49)％ for control group, and the difference was significant(P<0.05). The postoperative disc heights got improved, but lost in two groups 1 year after operation, but still higher than the preoperative ones, which of observation group was higher than control group; 1 years after operation, the fusion rates in observation group was 98.48%; while 87.88% for control group, which showed significant difference between two groups(P<0.05). Conclusions: TASPS is simple reliable for minimal invasive lumbar fusion. |
