Abstract:
Objective:To compare the accuracy and safety between percutaneous kyphoplasty (PKP) positioning device and traditional positioning device which posit entry point of pedicle of vertebral arch by using the C-arm X-ray.Methods: 117 patients with spinal centrum compression fractures were divided into positioning device group (57 cases) and Kirschner wire group (60 cases) depended on the entry point marked by the preoperative C arm X-ray irradiation. To compare the excellence rate, operation time and exposure times between PKP positioning device and traditional device.Results: The positioning times of the PKP positioning device group and Kirschner wire group were (2.3±0.9)min and (6.8±1.3)min, respectively. The exposure times of the two group were 1.6 times and 4.7 times, respectively. And both of the two differences were statistical significant (t=21.062,t=18.521;P<0.05). The puncture success rates of the two group were 100%. And the excellence rates of them were 93% and 87%, respectively, and the difference also was statistical significant (x2=2.761,P>0.05).Conclusion: There are series of advantages in developed PKP positioning device, such as portable, easy and simple control, higher accuracy and safety, less positioning time and exposure times of C arm X-ray.
