人膝关节交叉韧带血供的显微解剖学研究

Microanatomy on blood supply system in human knee cruciate ligament

目的探讨人类膝关节交叉韧带血供系统的具体形态。方法对12侧交叉韧带健康成人尸体膝关节进行肉眼和手术显微镜下解剖、组织学断层切片观察。结果交叉韧带全段均可见血管纵行交错分布,血管口径呈节段性变化,血管口径(0.03±0.01)～(0.09±0.02)mm。交叉韧带间束中存在大量的血管及脂肪组织,其表面血管口径最大为(0.18±0.04)mm。结论交叉韧带本身拥有足够充分的血供来源,存在自我修复的可能。

Objective To investigate the configuration of the blood supply system in human knee cruciate ligament.Methods Twelve cruciate ligaments derived from the knee joints of 6 healthy adult cadavers were observed under naked eyes,and then dissected and observed under a microscope.Three groups of anterior cruciate ligaments and posterior cruciate ligaments,randomly selected from the twelve cruciate ligaments,were observed through histotomy and HE staining.Results Blood vessels were found throughout the human knee cruciate ligaments,and the calibers of the blood vessels varied between 0.03±0.01 mm and 0.09±0.02 mm in different segments.Blood vessels and adipose tissues were abundantly found in the bands between the anterior cruciate ligaments and posterior cruciate ligaments,and the surface blood vessel calibers were not larger than 0.18±0.04 mm.Conclusion The human knee cruciate ligaments possess enough blood vessels to show promise in self repair.
