摘要:
目的探讨三维CT导航在胸椎椎弓根螺钉植入手术中的应用价值。方法24例行CT导航下椎弓根螺钉固定术，其中胸椎骨折14例，胸椎肿瘤6例，脊柱侧弯4例。向导航系统输入CT资料，选择配准方式为点匹配法，配准成功后，用导航棒预先设置螺钉的最佳位置、直径和长度，按导航计划立体、动态地植入螺钉，术后进行CT扫描，按Rampersaud分类法评估螺钉的位置。结果导航下成功对24例共植入144枚椎弓根螺钉。按Rampersaud分类法：A级136枚(944%)，B级6枚，C级1枚，D级1枚。术后无神经、脊髓损伤。22例平均随访8个月（6~14个月），复查X线片和CT，无螺钉松动和断裂钉，无迟发性脊髓损伤。结论三维CT导航系统可以准确引导胸椎椎弓根螺钉的植入。
Abstract:
ObjectiveTo evaluate the accuracy of 3DCT navigation in guiding pedicle screw fixation in the thoracic spine.MethodsThoracic pedicle screw placement guided by 3DCT navigation was performed on 24 cases, including 14 patients with thoracic spine fractures, 6 thoracic tumors, and 4 scoliosis. CT data was input into the navigation system, and pointmatching test was chosen. The optimal position, diameter, and length of the screw were set up using navigation stick after trueup. Then, the screw was placed dynamically in a stereo way according to navigation plan. After the operation, the position of the pedicle screw was assessed with CT using the Rampersaud grading system.ResultsUnder the guidance of 3DCT navigation, a total of 144 screws were successfully fixed into the 24 patients. According to the Rampersaud grading system, 136 of the screws were at grade A (94.4%), 6 at grade B, 1 grade C, and 1 grade D. No postoperative injury of the nerve or spinal cord was observed. Of the patients, 22 were followed up for a mean of 8 months (range，6-14 months). During the followup, no loose or breakage of the screw was detected by Xray and CT. No delayed spinal cord injury was found. ConclusionsThe thoracic pedicle screw placement can be accurately guided by 3DCT navigation.
