摘要 背景:颈椎关节突关节又称椎间小关节,与全身各种大关节一样属于滑膜关节。近年来解剖学和生物力学研究表明,颈椎关节突关节损伤、退变是引起慢性颈痛的最常见原因之一,现有研究主要集中于青少年和成人。目的:测量儿童下颈椎关节突关节的相关形态参数,探讨其发育规律和形态特征,为临床经关节螺钉固定提供解剖学参数。方法:选择4-6 岁儿童32 例,行下颈椎螺旋CT 扫描后三维重建,要求无骨质破坏、肿瘤、畸形、骨折等,椎骨形态结构未发生改变,既往无脊柱相关手术,监护人对试验方案知情同意,且得到医院伦理委员会批准。进行C3-C7 关节突关节相关形态测量及统计分析。结果与结论:①儿童颈椎关节突关节面无论高度还是宽度,在相邻两椎骨之间总是下关节面较上关节面小,由此推断出关节面的大小总是上关节面大于下关节面,根据高宽比例得出4-6 岁儿童下颈椎上关节突关节面从C3-C7 皆接近椭圆形,下关节突关节面从C3-C7 皆接近圆形,还未形成从圆形到椭圆形的过渡改变;②关节突关节内高变化趋势从C2-C7 在C4 节段出现最低点,总体呈先降后升趋势;③关节突间距先升后降,上关节突间距与下关节突间距除在C5 节段之间差异无显著性意义且达最大值,在C3 和C4 节段上关节突间距均小于下关节突间距,在C6 和C7 节段上关节突间距明显大于下关节突间距,这可能与重力传递和颈椎活动有关。 BACKGROUND: Zygapophysial joints of cervical vertebra is also called intervertebral facet joint. It is a synovial joint like the large joints of the body. In recent years, anatomical and biomechanical studies have shown that zygapophysial joints injuries and degeneration is one of the most common causes of chronic neck pain. Existing studies on this joint have focused on adolescents and adults. OBJECTIVE: The morphological parameters of children's inferior cervical zygapophysial joints were measured to explore their developmental rules and morphological characteristics, and finally to provide anatomical parameters for clinical zygapophysial joint screw fixation. METHODS: Totally 32 cases of children aged 4-6 years old with no changes in vertebral bone structure such as bone destruction, tumor, deformity or fracture in the inferior cervical spine and no previous spine related surgery were selected for three-dimensional reconstruction after cervical spiral CT scanning. Guardian signed the informed consent. This study was approved by the Hospital Ethics Committee. Morphological measurement and statistical analysis of C3-C7 zygapophysial joints were conducted. RESULTS AND CONCLUSION:(1) For children cervical zygapophysial joint articular surfaces in both height and width, between the adjacent two vertebrae, the lower articular surface was smaller than the upper articular surface, so it can be inferred that the size of the upper articular surface was always larger than that of the lower articular surface. According to the height to width ratio, the articular surface of the superior facet of the lower cervical spine in children aged 4-6 years was nearly elliptic from C3-C7;the articular surface of the inferior facet from C3-C7 was nearly circular. The transition from circular to elliptic shape had not yet been formed.(2) The trend of high change in facet joint was from the lowest point of C2-C7 in the C4 segment, and the overall trend was first down and then up.(3) The zygapophysial joints first rose and then fell, and
