Abstract:
Objective: To design a portable real-time monitoring tool for spine surgery and to preliminarily evaluate its application,so as to reduce the iatrogenic injury during the treatment of battle field spinal cord injury. Methods: A portable spine guiding device for spinal fixation was designed and prepared. The spinal specimens were randomly divided into control group (n = 10) and experimental group (n = 10). In the control group the way was cleared for the pedicle according to the doctor's experience; in the experimental group the way was cleared using our self-designed guiding device. The operation time was recorded in the two groups. After manipulation the specimens were opened along the pedicle level; the location and the depth of the needle were compared. Results;The manipulation time of a single vertebral body was (0. 5 + 0. 2) min in the control group and (0. 6 + 0. 1) min in the experimental group (P>0. 05). The edge of the puncture to the pedicle wall in the control group was significantly shorter than that in the experimental group ([1. 1 + 0. 3] vs [1. 8 + 0. 2] mm,P = 0. 037). Conclusion:The designed portable guiding device for spinal fixation is easy to carry, simple to operate; and initial in vitro application is satisfactory and can provide reliable reference for early operation.
