摘要

背景:在颈椎轴下准确放置椎弓根螺钉需要对椎骨解剖有精确的了解。乌干达人对颈椎轴下椎弓根的形态特征知之甚少。本研究旨在确定乌干达成年人颈椎轴下椎弓根的形态尺寸:我们于 2019 年 3 月至 11 月在坎帕拉 Nsambya 医院对颈椎 CT 扫描正常的乌干达成年人进行了横断面研究。研究连续招募了符合条件的参与者。研究人员通过结构化问卷收集 CT 扫描结果中有关基线特征和椎弓根尺寸的数据。数据使用 Stata 13.0 进行分析。以平均值和标准差总结不同水平颈椎椎弓根的尺寸,并用曼-惠特尼检验比较左右两侧女性和男性不同椎体水平的椎弓根尺寸,显著性水平设定为0.05:共研究了来自 49 名男性和 21 名女性参与者的 700 个轴下颈椎椎弓根(C3-C7)。椎弓根宽度直径从C3的1.65(0.63)毫米逐渐增加到C7的3.46(0.75)毫米。椎弓根高度也显示出向尾部增加的趋势,女性椎弓根直径在C3最小(1.98(0.76)毫米),在C5最大(3.67(6.42)毫米),男性在C7最大(3.83(0.76)毫米)。所有级别的椎弓根高度都比椎弓根宽度宽。雌雄的椎弓根弦长向尾部逐渐增加,从C3的29.08(1.35)毫米到C7的32.53(3.19)毫米。轴向角度朝向内侧,在50°和53°之间没有一致的趋势。矢状角随着C3到C7的移动而减小。女性的尺寸明显小于男性:结论:各级椎弓根骨膜宽度均小于椎弓根高度。椎弓根脊髓长度向尾部增加。除角度外,女性的椎弓根尺寸均小于男性。

Pedicle Morphometry of Subaxial Cervical Spine Using Computed Tomography Scans among Adult Ugandan Subpopulation.

Background: Accurate placement of pedicle screws in the subaxial cervical spine requires precise understanding of vertebra anatomy. Little is known about the morphometric characteristics of the subaxial cervical pedicle in the Ugandan population. The objective of the study was to determine the morphometric dimensions of pedicles in the subaxial cervical spine among the adult Ugandan population.

Methods: We conducted a cross-sectional study from March to November 2019 among adult Ugandans with a normal cervical CT scan at Nsambya hospital in Kampala. Eligible participants were consecutively recruited into the study. Data on baseline characteristics and pedicle dimensions from the CT scan finding was collected using a structured questionnaire. Data was analysed using Stata 13.0. Pedicle dimensions for the different levels of subaxial cervical vertebrae were summarised as means and standard deviations, the Mann-Whitney test was used to compare pedicle dimensions for the different vertebra levels among females and males on both right and left sides, and the level of significance was set at 0.05.

Results: A total of 700 subaxial cervical pedicles (C3-C7) from 49 males and 21 female participants were studied. Pedicle width diameter showed cephalocaudal gradual increment from C3 1.65(0.63) mm to 3.46(0.75) mm at C7. Pedicle height also showed an increase caudally with smallest diameter at C3 (1.98(0.76) mm) and largest at C5 in females (3.67(6.42) mm) and at C7 in males (3.83(0.76) mm). The pedicle height was wider than the pedicle width at all levels. The pedicle chord length gradually increased caudally in both sexes ranging from 29.08(1.35) mm at C3 to 32.53(3.19) mm at C7. The axial angles were oriented medially and showed no consistent trend ranging between 50° and 53°. The sagittal angles decreased as one moved from C3 to C7. The dimensions of females were significantly smaller than in males.

Conclusion: Pedicle endosteal width was smaller than pedicle height dimensions at all levels. Pedicle cord length increased caudally. The pedicle dimensions, except angulations, were smaller in females than in males.
