Abstract：Objective To evaluate clinical effects of positioning guidance assisted instrument for percutaneous pedicle puncture during percutaneous vertebroplasty (PVP). Methods According to randomized prospective controlled design, 52 patients underwent PVP from July 2013 to March 2014 were divided randomly into two groups, instrument-assisted puncture group and free hand puncture group. X-ray fluoroscopy times and time of puncture in two groups were recorded and compared with each other. Visual analogue scale (VAS) scores of pain were evaluated to access the clinical effects, and the complications were also observed. Results X-ray fluoroscopy times and puncture time in instrument-assisted puncture group and free hand puncture group were 8.5 ± 1.8, 15.8 ± 2.1 and (18 ± 3) min, (31 ± 4) min respectively, the difference between two groups had statistical significance (P <0.05); Four weeks after the surgery, VAS scores were (2.1 ± 1.4) and (2.3 ± 1.6) respectively, there were no statistical differences between two groups (P >0.05). Spinal cord injury symptoms were not found during the operation, and no postoperative bleeding or wound infection had happened, wound healing rate was 100%. Conclusion Percutaneous pedicle puncture positioning guidance instrument is helpful for PVP procedure which could reduce X-ray fluoroscopy times, shorten the operation time, and obtain similar short-term effects as free hand puncture.
