【摘要】：目的:探讨膝关节翼状韧带形态分型及其与后交叉韧带上止点的解剖关系。方法:解剖13个新鲜冷冻膝关节(左膝6个,右膝7个),观察记录翼状韧带的不同形态,并观察翼状韧带股骨止点与后交叉韧带上止点的解剖关系。并对后交叉韧带上止点-翼状韧带股骨止点做组织切片,HE染色观察。结果:通过解剖13个膝关节,发现膝关节存在一个从前至后的纵隔结构,其前方与脂肪垫相连,通过翼状韧带,前、后交叉韧带之间,向后方形成膝关节的后纵隔。13个膝关节中,翼状韧带均从后交叉韧带的外缘绕过,通过前、后交叉韧带之间连接后纵隔。通过解剖,发现翼状韧带从形态学上分为3型:完整型(膜型),2个,占15.4%;不完整型(分离型),10个,占76.9%;缺如型,1个,占7.7%。另外,还发现翼状韧带的股骨止点与后交叉韧带的股骨止点连接靠近,组织切片上密切连接。结论:膝关节翼状韧带从形态学上可以分为完整型(膜型)、不完整型(分离型)和缺如型三种类型,并且与后交叉韧带上止点的解剖关系密切。
[Abstract]:Objective: to study the morphological classification of the wingform ligament of the knee joint and its anatomic relationship with the insertion point of the posterior cruciate ligament. Methods: 13 fresh frozen knee joints (6 left knee and 7 right knee) were dissected to observe and record the different shape of the wingform ligament, and to observe the anatomical relationship between the femoral insertion point of the wingform ligament and the superior end point of the posterior cruciate ligament. The histopathological sections were stained with HE staining for the femoral insertion of the posterior cruciate ligament and the femur of the pterygoid ligament. Results: by dissecting 13 knee joints, we found that there is a mediastinal structure from front to back, the front of which is connected with fat pad, through the winglike ligament, between the anterior cruciate ligament, and between the anterior and posterior cruciate ligaments. The posterior mediastinum of the knee joint was formed to the rear. In 13 knee joints, the winglike ligament was circumvented from the outer edge of the posterior cruciate ligament and connected with the posterior mediastinum through the anterior and posterior cruciate ligaments. Anatomically, we found that the wingform ligament was divided into three types: intact type (membranous type, 2 types, accounting for 15.4%), incomplete type (separated type, 10 types, accounting for 76.9%), absent type, 1 type, accounting for 7.7%. In addition, it was found that the femoral insertion of the pterygoid ligament was close to that of the posterior cruciate ligament, and the tissue section was closely connected. Conclusion: the pterygoid ligament of the knee joint can be divided into three types: complete type (membrane type), incomplete type (separation type) and absence type, and it is closely related to the anatomical relationship between the apical point of the posterior cruciate ligament and the posterior cruciate ligament.
