我们提出一种新椎弓根通道分类描述当椎弓根导针植入遇到的骨性解剖结构。
We propose a novel pedicle channel classification describing the osseous anatomy encountered during pedicle probe insertion.
一种新椎弓根通道分类描述骨性解剖结构:有多少胸椎侧弯椎弓根有松质骨通道?
Title: a Novel Pedicle Channel Classification Describing Osseous Anatomy: How Many Thoracic Scoliotic Pedicles Have Cancellous Channels?
结论:我们提出一种椎弓根通道分类描述当椎弓根导针植入遇到的骨性解剖结构。
CONCLUSION. : We propose a classification for pedicle channels describing the osseous anatomy encountered during pedicle probe insertion.
研究目的:确定胸椎侧弯椎弓根有多少松质骨、皮质骨及缺如通道。
OBJECTIVE. : To determine how many thoracic scoliotic pedicles have cancellous versus cortical versus absent channels.
应用数字技术探讨中下预推椎弓根在头尾偏角不变而不同外偏角方向通道投影的变化规律。
To investigate the regularity changing of inferior cervical pedicle channel in different angles of transverse plane direction.
结果:超声图影像对人类尸体腰椎标本椎弓根钉骨通道的显示中99%的都是准确的。
Results. Ultrasonographic images of pedicle screw holes in postmortem human spine specimen were correctly interpreted in 99% of cases.
基于这个分类,令人意外的,我们发现当手术时90%胸椎椎弓根是松质骨通道,7%为皮质骨通道,仅有3%缺如通道。
Based on the classification, surprisingly, we found during surgery that 90% of thoracic pedicles had a cancellous channel, whereas 7% had a cortical channel and only 3% had an absent channel.
结论:对于在椎弓根螺钉放置前术中评估椎弓根螺钉进针骨通道而言,骨内超声检查一项很可靠的技术。
Conclusion. Intraosseous ultrasound is a highly reliable technique for the intraoperative assessment of pedicle screw holes before pedicle screw placement.
方法:在2具人类尸体腰椎标本的24个椎弓根设置椎弓根螺钉骨通道。
Methods. Pedicle screw holes were placed in 24 pedicles of 2 postmortem human lumbar spine specimens.
方法:在2具人类尸体腰椎标本的24个椎弓根设置椎弓根螺钉骨通道。
Methods. Pedicle screw holes were placed in 24 pedicles of 2 postmortem human lumbar spine specimens.
