摘要
Abstract
BACKGROUND:Pedicle screw fixation has been used in children with thoracic injury. Conventional method is screw implantation by hand. This method can meet the needs of surgery, but its accuracy was low, and incidence of complications was high. The application of digital image navigation aid module is possible. OBJECTIVE:To study accuracy and safety of digital image navigation aid module in thoracic pedicle screw placement. METHODS:Eight thoracic vertebral bodies were equal y and randomly assigned to the manual insertion group and the digital image navigation aid module group. Manual insertion group received manual screw insertion. In the digital image navigation aid module group, navigation aid module was made according to CT scan results combined with principle of reverse engineering and rapid prototyping. Pedicle screw was placed using the digital image navigation aid module. RESULTS AND CONCLUSION:(1) Success rate of once screw set was significantly higher in the digital imaging navigation aid module group than in the manual insertion group (P<0.05). (2) Twenty-eight screws were implanted in the digital image navigation aid module group and manual insertion group separately. The excellent and good rate of screw placement was 96%in the digital image navigation aid module group and 75%in the manual insertion group (P<0.05). (3) These findings suggested that digital image navigation aid module can effectively improve the success rate of pedicle screw insertion. Moreover, this method is simple, easy to operate, and can make a personalized nail placement program for each child.关键词
