【摘要】 胸腰椎椎弓根螺钉内固定技术的开展,有力地推动了脊柱外科的发展。该技术的关键是,螺钉的植入必须位于三维空间中唯一的一个正确通道上,即按照正确的矢状面角及水平面角,沿椎弓根的长轴穿过椎弓根这一狭小的骨性管道达椎体内。近年来,胸腰椎椎弓根螺钉植入技术的研究取得了很大发展,尤其是术中监测手段,已从传统的X线透视或摄片监测定位发展到计算机辅助技术进行可视化监测。本文结合国内外研究成果,对胸腰椎椎弓根螺钉植入技术的研究进展进行概述。更多还原

【Abstract】 Application of the techniques of pedicle screw fixation in t horacolumbar spine has forcefully promoted the development of spinal surgery. Th e key to the techniques is that the pedicle screw insertion must be located into the sole exact routeway of the three-dimensional-space, that is, into the inn er vertebral body through the pedicle according to the exact arrow plane angle a nd horizontal plane angle. Recently great development has been made in the resea rch on the techniques of pedicle screw insertion in thoracolumbar spine, especia lly in the supervising means during operation. The means have been developed fro m the traditional X-ray perspective or photograph apposition to the application of computer-assisted technique. This paper reviews and discusses the current d evelopment and prospects in the research on the techniques of pedicle screw inse rtion in thoracolumbar spine.更多还原
