Abstract:

Objective To compare advantage and disadvantage of two different methods for placing the translamina facet screw. Methods The study reviewed 47 patients of low lumbar vertebra diseases underwent the surgery. 21 cases were placed screw by opening procedure, the others were placed screw by the percutanous gunsight guiding. There was no difference among the gender, age, history time, diseased type, diseased region and severity in two groups. Results All cases underwent the surgery successfully, with no complication occurred intraoperatively and postoperatively. There was significant differences among the times of intraoperative guide pin puncture, length of incision, operative time, intraoperative bleeding, postoperative incisal draining and postoperative screws location in two sets. All cases were followed-up for 12 to 36 months, averagely 19 months. 44 cases got bony fusion, only 3 suffered from poor bony fusion. Improving rate of the JOA grades was insignificant different in two sets. Conclusions Compared to that of opening fixation, the screw placing through percutanous gunsight guiding is more prevalent, such as the small surgery trauma, simple operation, high intraoperational safety, and short manipulation time. Therefore, gunsight is a good choice for translamina facet screw fixation.
