文题释义:
骶髂关节:由骶骨与髂骨的耳状面相对而构成。关节囊紧张,并由坚强的韧带进一步加强其稳固性,运动范围极小,主要是支持体质量和缓冲从下肢或骨盆传来的冲击和震动。在结构上属于滑膜关节,从运动方式上可看做屈戌关节或滑车关节。其大小个体差异较大,即使在同一个人两侧也不尽相同。
椎弓根定位:椎弓根是椎弓的一部分,起于椎体后上部,短而厚,与椎体方向垂直向后方突起,其外形呈弧形,与椎体、关节突和椎板融合在一起,椎弓根是组成椎间孔的组成部分,其上方有一较浅的切迹构成椎间孔的下壁,椎弓根下方有一较深的椎弓根下切迹构成椎间孔上壁,由于椎弓根解剖关系稳定,使其可以作为解剖标志。
 
摘要
背景:经椎弓根定位骶髂关节导向器较传统手术治疗骨盆后环骨折不仅缩短手术时间和术中透视量,而且提高了手术的安全性。
目的:评价经椎弓根定位骶髂关节螺钉导向器应用于人体标本的临床可行性,为应用于临床提供基础数据。
方法:5例人尸体骨盆(10例骶髂关节)中,在自创设计的经椎弓根定位骶髂关节导向器引导下将10枚经皮骶髂关节螺钉安全通过骶髂关节并置入S1椎体内,并通过透视确认骶髂关节螺钉位置是否安全。
结果与结论:①经影像学验证,所有骶髂螺钉置入位置准确,均未出现突破前方骨皮质或进入椎管情况;②使用椎弓根定位骶髂关节导向器引导,置入骶髂关节螺钉固定,效果明确;③提示经椎弓根定位骶髂关节螺钉治疗骨盆后环骨折准确性高,固定效果较好,同时显著降低手术操作风险,大幅度减少术中透视,而且对操作者要求降低,学习曲线减短,可以更广泛的应用于临床实践操作中。

Abstract:

BACKGROUND: Transpedicular positioning of the sacroiliac joint guider is more effective than traditional operation in the treatment of posterior pelvic annulus fracture. It not only shortens the operation time and intraoperative fluoroscopy, but also improves the surgical safety.

OBJECTIVE: To evaluate the clinical feasibility of the transpedicular positioning of the sacroiliac screw guider,  and to provide basic data for clinical application.
METHODS: In five cases of human cadaver pelvis (10 sacroiliac joints), 10 sacroiliac screws were implanted into S1 through sacroiliac joint under the guidance of the self-designed sacroiliac screw guider. The safety of placement was confirmed by fluoroscopy.
RESULTS AND CONCLUSION: (1) All the sacroiliac screws were implanted accurately, and none of them broke through the anterior cortical bone or entered the spinal canal. (2) The pedicle screws were used to guide the sacroiliac joint guidance with stable screw placement, and satisfactory efficacy. (3) These results indicate that transpedicular localization of sacroiliac screws in the treatment of posterior pelvic ring fractures shows high accuracy, good fixation effect, and can decrease operation risk, significantly reduce intraoperative fluoroscopy, reduce the requirements for the operator, and shorten the learning curve, which can be widely used in clinical practice.
