【摘要】：背景:经后路椎弓根螺钉钉棒系统内固定是各种腰椎手术的主要术式,其成功的关键是椎弓根螺钉的准确置入,但棘突是位置表浅的解剖标志,在术中有较大的参考价值。目的:分析东北地区成人腰椎棘突倾斜情况,并进行解剖分级,同时讨论其作为椎弓根螺钉内固定手术局部解剖学定位标志参考的可行性。方法:对97例东北地区成人腰椎棘突倾斜角度进行测量,并根据倾斜角度进行分型;对各研究对象进行模拟手术,确定椎弓根螺钉的最佳置钉角度,测量椎弓根螺钉与棘突、标准矢状面夹角,对二者进行差异性比较。结果与结论:(1)腰椎各型分布如下:型占75.1%,Ⅱ型占20.9%,Ⅲ型占2.3%,Ⅳ型占1.7%,经比较椎弓根螺钉与棘突、标准矢状面夹角无明显差异;(2)结果说明,腰椎棘突倾斜角度存在不同程度变异,腰椎手术前应通过相关检查明确变异情况,棘突可做为椎弓根螺钉置钉时倾斜角度的参考。
[Abstract]:Background: posterior pedicle screw system internal fixation is the main method of lumbar spine surgery. The key to its success is the accurate placement of pedicle screw, but the spinous process is the anatomic sign of superficial position and has great reference value during operation. Objective: to analyze the obliquity of spinous process of adult lumbar vertebrae in Northeast China, and to discuss the feasibility of using it as a reference for local anatomical localization of pedicle screw fixation. Methods: the inclination angle of lumbar spine process of 97 adults in Northeast China was measured and classified according to the angle of inclination, the optimal angle of pedicle screw was determined by simulated operation, and the pedicle screw and spinous process were measured. The standard sagittal angle was compared. Results and conclusions: (1) the distribution of lumbar vertebrae was as follows: type 鈪，
