在O-arm导航辅助下植入椎弓根螺钉,术中O-arm导航3D重建半椎体畸形,明确半椎体切除范围,彻底切除半椎体畸形.术中经O-arm扫描,术后经CT扫描观察螺钉位置;分析手术前后Cobb角,评价脊柱侧凸,后凸矫正率.结果14例患者共置入椎弓根螺钉120枚,其中11例置入4对椎弓根螺钉,2例置入5对,1例置入6对;经术中O-arm扫描...
总结46例青少年特发性脊柱侧凸患者O-arm导航下行脊柱侧凸微小胸椎椎弓根手术护理配合难点.该手术配合难点应对包括:术前访视重点评估患者的体态,颈椎,肩关节功能,并根据患者体态情况设定体位方案;O-arm导航设备放置与维护,保持手术间空间及布局有序;由于本组患者均呈不同程度的后凸畸形,根据患者Cobb角与肩关节功能情况...
而采用术中O-Arm 3D图像加导航技术还没有颈椎神经血管损伤的报道[11],这也是本文采用此技术的原因。 2.3注意事项。由于病例的稀缺,本文仅报道1例术中O-Arm 3D成像和导航下颈椎前路椎弓根钉植入,其有效性和安全性需要更多病例验证。作者报道了采...
O-Arm和导航系统均是美国Medtronic公司产品,O-Arm可全方位旋转和3D成像,导航可实时影像指导。带有反射球的参考架安放固定在锁骨上,O-Arm在手术区扫描和成像,与导航数据匹配,指示针注册。在导航系统三维影像引导下,用指示针选择椎弓根最佳的进针点和方向(图2),安放1.2mm导针。 图2. (A)参考架安放固定在锁骨上。
416 screws (32 having surgery using O-arm-based navigation); postoperative CT studies confirmed the accuracy of screw placement, and no significant differences in the frequency of grade 2-3 perforations between the two groups. Nelson et al. analyzed the radiation exposure delivered to the ...
The O-armTMsystem is an intraoperative 2D/3D imaging system that is designed to meet the workflow demands of the surgical environment. It can be used in variety of procedures including spine, cranial, and orthopedics. INDICATIONS The O-arm™ O2 Imaging System is a mobile x-ray system desig...
This study evaluates and compares using the O-arm庐 system and radioscopy in the freehand technique in spine surgeries. For this, searches were conducted in PubMed and Embase for randomized and non-randomized studies using the O-arm庐 system and radioscopy in spine surgery. Twenty-four ...
