文题释义:
横断面椎弓根宽度:横断面椎弓根内外侧皮质外缘之间的最短距离。
椎弓根螺钉置入深度:椎弓根螺钉进钉深度与内固定系统的稳定性呈正相关性,随着进钉深度增加,内固定系统的稳定性呈增高趋势。并且只有进钉深度足够,才能保证从椎弓根传递到脊柱的力量通过椎体的力学核心,抵抗了前柱损伤造成的轴向剪切力,有效提高了骨折后脊柱的稳定性。提示脊柱外科内固定手术中,在确认椎弓根螺钉不穿透椎体前缘皮质的前提下,应尽可能地增加进钉深度,以增加内固定的生物力学稳定性。
 
摘要
背景:胸腰段(T11-L2)由于其特殊的解剖结构与生物力学特征而容易发生损伤,因此术前充分的了解椎弓根形态及术中寻找有形的、恒定的、且顺应椎弓根轴线的进钉点标志对安全置入椎弓根钉极为重要。
目的:CT扫描并测量汉族与维吾尔族男性胸腰段椎弓根应用解剖的相关参数,为临床应用椎弓根螺钉内固定提供应用解剖学资料。
方法:用CT对120例成年男性受检者(汉族60例,维吾尔族60例)的胸腰段(T10-L3)椎体进行扫描,扫描后的图像行三维重建,在骨窗窗位下使用浏览器中角度及长度测量工具测量并记录横断面椎弓根宽度(TPW),椎弓根轴线长度(PAL),椎弓根横断面角(TPA)和椎弓根矢状面角(SPA)。同时记录受检者的年龄、身高。以上数据运用SPSS 13.0软件进行统计学处理。
结果与结论:①汉族组在T12和L1节段的横断面椎弓根宽度均值大于维吾尔族;②汉族组在T12和L2节段的椎弓根横断面角均值大于维吾尔族;③汉族组在T11和L1节段的椎弓根轴线长度和椎弓根矢状面角均值大于维吾尔族,差异有显著性意义(P < 0.05)。④实验所测量汉族与维吾尔族男性胸腰段弓根各径线的数据部分有差异,任何椎弓根形态测量所得的均数值只能为安全置入椎弓根螺钉提供一个参考。在椎弓根螺钉置入术前行CT测量相关参数,并制定个体化置钉方案,能有效降低因误置而导致的不必要的术后并发症发生率。

Abstract:

BACKGROUND: Thoracolumbar segments (T11-L2) prone to damage due to its special anatomical and biomechanical characteristics. Therefore, fully understanding the shape of pedicle of vertebral arch and finding the visible, constant, and the point of insertion of the pedicle axis is very important to the safety of pedicle screw placement.

OBJECTIVE: To measure the surgically relevant parameters of thoracolumbar pedicles between Han and Uygur males using computed tomography (CT) scan to provide some anatomic reference data for pedicle screw fixation.
METHODS: The vertebral bodies and pedicles of adult males were scanned (60 cases of Han people and 60 cases of Uygur people) from T10-L3 with CT. The parameters were processed by three-dimensional reconstruction. Transverse pedicle width, pedicle axis length, transverse pedicle angle, and sagittal pedicle angle were measured by using length and angle measurement tool of browser in bone-window CT images. The age and stature information were recorded. All the data above were processed by SPSS 13.0 software.
RESULTS AND CONCLUSION: (1) The mean transverse pedicle width of T12 and L1 in Han was bigger than that in the Uygur. (2) The mean transverse pedicle angle of T12 and L2 in Han was bigger than that in the Uygur. (3) The mean pedicle axis length and sagittal pedicle angle of T11 and L1 in Han were bigger than that in the Uygur (P < 0.05). (4) There were some differences among some parameters of the thoracolumbar pedicles between the Han and Uygur people. Data from any study only can be used as a guide for pedicle screw fixation. Preoperative CT evaluation may provide an individualized strategy to reduce the incidence of postoperative complications caused by misplacement.
