X-ray and CT scan were performed at operated levels post-operatively to evaluate the accuracy of the pedicle screw insertion.
术后行植入螺钉节段的X线平片及CT扫描以确定螺钉植入情况。
They recommended that pedicle screw insertion at the cephalad level be performed percutaneously if one desires to minimize denervation of the multifidus complex at the cephalad adjacent level.
他们建议，如果术者希望将上位相邻节段的多裂肌束去神经化降至最低，应利用经皮技术在头侧节段置入椎弓根螺钉。
Objective: Cortex thicknesses of subaxial cervical pedicle entrys circumferential structures were measured on planar ct images to provide quantitative data for cervical pedicle screw insertion.
目的：对下颈椎椎弓根四壁及入口毗邻结构的皮质厚度行影像学测量，为临床椎弓根钉植入提供参考。
The rationale for minimally invasive pedicle screw insertion into the spine, which can be performed percutaneously or via a paramedian mini-open technique, is to preserve multifidus muscle function.
经皮或应用旁正中小切口技术完成的微创脊柱椎弓根螺钉内固定术的原理是保留多裂肌功能。
As a result, insertion of a pedicle screw through the mammillary process at one level can cause injury to the medial branch of the dorsal rami that supplies the adjacent cephalad level.
因此，在一个节段经乳突置入椎弓根螺钉可引起支配相邻关节突关节头侧水平结构的后内侧支损伤。
