用胎儿、新生儿20侧和成人尸体8侧上肢,动脉注射明胶墨汁后,用大体解剖法、透明法、显微解剖法,观察肘关节的动脉供应和血管构筑。动脉在关节周围和关节囊表面吻合成网,并发出分支进入关节囊纤维层,形成梯形血管网;在关节囊附着部纤维层与滑膜层间吻合,形成关节血管环,由血管环发出分支供应滑膜、滑膜皱襞和脂肪垫、骺或骺部的软骨,其分布形态因结构不同而异。关节囊滑膜内有2～4层平行的血管网;滑膜皱襞和脂肪垫内血管吻合成团;复盖骨表面的滑膜内有多级弓状环形血管网。血管网末端发出毛细血管襻伸到滑膜关节腔面下。在胎儿、新生儿,肘关节骺部软骨内有大量软骨管,管内有中央动脉及笼状毛细血管网,次级骨化中心出现在软骨管密集、血液供应丰富的部位。骺板骨化前,干骺端动脉和滋养动脉在骺板骨干侧吻合成襻,与骺内血管无吻合交通。
With the fetus, 20 newborns and adult body 8 sides of the upper extremities, arterial injection of gelatin ink, with general anatomy, the method of transparency, microscopic anatomy, the elbow arteries and vascular architecture. Arteries in the joints and the surface of the articular capsule coincide with the network, and issued a branch into the capsule capsule fiber layer, the formation of trapezoidal vascular network; in the joint capsule fibrous layer and synovial layer between the anastomosis, the formation of joint vascular ring, the branch issued by the vascular ring Supply of synovial membrane, synovial folds and fat pads, epiphyseal or epiphyseal cartilage, the distribution of morphological differences due to different structures. Synovial membrane within the joint 2 to 4 parallel vascular network; synovial folds and fat pad vascular anastomosis; covering the surface of the synovial surface of the multi-level arcuate annular vascular network. End of the vascular network issued capillaries 襻 extended to the synovial cavity surface. In the fetus, newborn, elbow epiphyseal cartilage within a large number of cartilage, the tube has a central artery and cage capillary network, the secondary ossification center in cartilage dense, rich blood supply sites. Epiphyseal ossification before, metaphyseal artery and nourishing artery in the epiphyseal side of the backbone of the anastomosis 襻, and intrahepatic blood vessels without traffic.
