中文摘要:

目的:设计一种椎弓根螺钉的植入方法,提高椎弓根螺钉的植入准确率。

方法:对20组胸腰段椎体标本的椎弓根的测量及其形态学的研究,选用坐标方式进行进针点标识,纵轴小关节面上顶点作垂直线为纵轴,横突纵轴为坐标横轴,用Φ2mm克氏针从进针点循椎弓根方向入针约15~20mm处,剪去骨外部针尾,留置定位用,并通过透视或拍摄前后位片,了解定位针头与椎弓根的关系,指导我们进行椎弓根螺钉的植入。

结果:应用本方法在20组胸腰段(T10~L5)椎体标本上进行椎弓根螺钉植入的研究表明:T10至L5的进针点呈节段性变化。本方法设计合理,准确率达100%,临床上应用于86例胸腰段骨折患者,其中爆裂型骨折42例,压缩性骨折34例,Chance骨折4例,骨折脱位6例,置钉的优良率达93.6%.

结论:本方法是椎弓根螺钉植入的一种实用有效方法,临床应用证明操作简便可靠,能有效提高植入的成功率

The study of implantation position of screw into thoraco lumbar pedicle of vertebral arch by using system of coordinates and its changes with different segments
ABSTRACT  

Objective:To design an implantation method of pediculus arcus vertebrae screw,so as to increase accuracy of implantation

Methods:The pedicle of vertebral arch of 20 thoraco lumbar vertebral specimens were measured and the morphological study was done in the experiment.All implantation positions were signed in frame of axes,of which vertical line from topmost of longitudinal small articular facet was used as vertical ordinate and transverse process longitudinal as horizontal coordinate.The Kirschner pin of 2mm was implanted into pedicle of vertebral arch of patients for about 15~20 mm from implantation positions which had been determined in experimental study and the outside part of the end of the pin was cut.Fluoroscopy examination was performed or A P position X ray photo was taken to observe the location relationship of the head of the pin with pedicle of vertebral arch,so as to introduce the implantation of pediculus arcus vertebrae screw.

Results:The implantation positions of T10 ~L5 showed segmental changes.The experimental study showed that this method is reasonably designed and the accurate ratio reached to 100%.86 patients of fracture of thorace lumbar vertebral were treated with this implantation method,in which 42 cases were of burst type,34 with compression fracture,4 with Chance fracture and 6 with fracture dislocation.The excellent and good rate of 93.6% was obtained.

Conclusion:This is a practical and effective method for implantation of pediculus arcus vertebrae screw.It can be carried out easily,fixed with stability and effective with successful ratio of implantation.
