Abstract:Abstract: [Objective] To investigate the accuracy and feasibility of digital technology assisted percutaneous pedicle puncture in the treatment of thoracolumbar fracture. [Methods] A prospective controlled case analysis was conducted to analyze 73 patients who underwent percutaneous vertebroplasty for single-segment osteoporotic vertebral compression fractures in our hospital from January 2019 to August 2020. The patients were divided into two groups by random number method: 37 patients in the traditional group underwent vertebroplasty via traditional unilateral pedicle approach,while the remaining 36 patients in the digital group were performed vertebroplasty via unilateral pedicle approach with the guide of preoperative 3D digital models and data measurement. The operative time, puncture time, intraoperative total fluoroscopy times, injection volume of bone cement and complication rate, anterior vertebral height, Cobb’s angle, visual analogue scale (VAS) , Oswestry disability index (ODI) and JOA scores at different period (preoperatively, 3 days and 6 months postoperatively) were compared between the two groups. [Results] The operative time showed that digital group 0.05). VAS, ODI scores and JOA scores in both groups were significantly improved postoperatively (P<0.05), The VAS score showed that didital group(3.52±0.94) was less than the conventional group (4.19±0.81) and the ODI showed that didital group(34.56±4.06)% was less than the conventional group (37.12±5.78)% while the JOA scores show that digital group(25.31±1.24) was higher than the counterpart(24.54±1.35) 3 days postoperatively(P<0.05). There was no significant difference in the amount of bone cement injection and the leakage rate between the two groups (P>0.05). [Conclusion] Digital technology assisted percutaneous pedicle puncture can improve the accuracy of thoracolumbar percutaneous pedicle puncture, which helps to reduce the times of fluoroscopy and operation time and has better postoperative effect, can be used for thoracolumbar percutaneous pedicle puncture surgery.
