The aim of this study is to compare the identification of the sacral cornua using palpation and ultrasound, and to evaluate the sacrococcygeal area via ultrasound across different age groups of children.
This study included 348 children aged 1 to 84 months, who were divided into three age groups: 1-24 months, 25-48 months, and 49-84 months. Sacral cornua were assessed using both palpation and ultrasound imaging. Palpation findings were categorized as "good", "difficult", or "non-palpable". Ultrasound imaging of the sacral cornua was classified as "clear", "unclear", or "invisible". Measurements taken included the inter-cornual distance, the anteroposterior diameter of the sacral canal, the distance from the skin to the sacral canal, and the distance from the dural sac to the cornua level.
Palpation of the sacral cornua was rated as "good" in 75.9% of patients, "difficult" in 22.4%, and "non-palpable" in 1.7%. All patients with "good" cornua palpation were also classified as "clear" on ultrasound imaging. Among the cases with "difficult" palpation, 76% showed a "clear" ultrasound image, while 24% were "unclear". Only one patient had "invisible" cornua on ultrasound. The mean distance from the dural sac to the cornua level was 3.72±1.64 cm, and this distance increased significantly with age ( < 0.01).
Ultrasound is a valuable tool for identifying the sacral cornua, especially when palpation is difficult, and offers reliable, detailed information on sacral anatomy.
本研究旨在比较通过触诊和超声识别骶角的情况，并通过超声评估不同年龄组儿童的骶尾区域。
本研究纳入了348名年龄在1至84个月的儿童，他们被分为三个年龄组：1至24个月、25至48个月和49至84个月。使用触诊和超声成像对骶角进行评估。触诊结果分为“良好”、“困难”或“无法触及”。骶角的超声成像分为“清晰”、“不清晰”或“不可见”。测量指标包括角间距离、骶管前后径、皮肤至骶管的距离以及硬脊膜囊至骶角水平的距离。
75.9%的患者骶角触诊评为“良好”，22.4%评为“困难”，1.7%评为“无法触及”。所有骶角触诊“良好”的患者在超声成像上也被分类为“清晰”。在触诊“困难”的病例中，76%的超声图像显示“清晰”，24%“不清晰”。只有一名患者的骶角在超声上“不可见”。硬脊膜囊至骶角水平的平均距离为3.72±1.64 cm，且该距离随年龄显著增加（<0.01）。
超声是识别骶角的重要工具，尤其是在触诊困难时，并且能提供关于骶骨解剖结构的可靠、详细信息。
