Abstract

The angle between the base of the sacrum and its pelvic surface (SA), and the lumbosacral curve (LSC) defined as the anteroposterior distance between the L1 vertebra and the sacrum were studied in 105 fresh cadavers aged 15–32 years at death. The sample is comprised of 27 black males, 20 black females, 37 white males and 21 white females. Measurements of the SA were made with an adjustable protractor with an accuracy of ±1°. A new method using a specially designed instrument was developed for taking LSC measurements. A sliding scale that could be moved in the cranialcaudal direction was fitted with a measurement stick which measured the depth of the lumbar and sacral vertebral bodies (ventral to dorsal). The measuring device was placed on the autopsy table above the supine cadaver to measure these depths from the ventral side. The LSC was calculated as the mean difference between lumbar and sacral depths. The SA is smaller in black than in white men (43.6 ± 3.4 vs. 61.7 ± 2.1°, p <0.001). Similarly, black women have a smaller SA than white women (36.0 ± 2.2 vs. 50.2 ± 1.9°, p <0.001). The LSC is also larger in black than white men (9.4 ± 1.1 vs. 5.1 ± 0.3 cm, p <0.001), and black women also have significantly larger LSC compared to white women (13.2 ± 0.5 vs. 9.2 ± 0.6 cm, p <0.001). These data are so far the largest empirical evidence of differences in the SA and the LSC in young black and white cadaver specimens.
黑人和白人青年男女的骶骨角度和腰骶曲度的差异。
本文研究了105具年龄在15-32岁的新鲜尸体的骶骨底与骨盆表面之间的夹角(SA)和腰骶曲线(LSC), LSC定义为L1椎体与骶骨之间的前后距离。样本由27名黑人男性,20名黑人女性,37名白人男性和21名白人女性组成。SA的测量是用一个精度为+/-1度的可调量角器进行的。开发了一种利用特殊设计的仪器进行LSC测量的新方法。可在颅尾方向移动的滑动刻度配有测量棒,测量腰椎和骶椎体的深度(从腹侧到背侧)。测量装置放置在仰卧尸体上方的解剖台上,从腹侧测量这些深度。LSC计算为腰椎和骶骨深度的平均差值。黑人的SA小于白人(43.6 +/- 3.4度vs. 61.7 +/- 2.1度,p
