Abstract:
After the arteries were injected with gelatin and ink, the arterial distribution and the vascular architecture of the elbow joint were observed in 20 fetal and 8 adult arms macroscopically and microscopically. The arteries of the elbow anastomose to form networks around the joint, from which many twigs supply the capusle and the intra-articular structures. In the capusle, the vessels make up a ladder-like mesh among the fibrous bundles. At the margin of the capusle, the vessels ramify to form a complex network, the circulus articuli vasculosus, between the fibrous and the synovial layers. The vessels from the circulus articuli vasculosus supply the synovial membrane, the synovial fold or the fat pad and the epiphysis or the epiphyseal cartilage. There are 2 to 4 layers of mesh in the synovial membrane of capusle, a glomerulus-like network in the synovial fold or the fat pad, many series of bow-shaped net in the synovial membrane on the surface of the neck of elbow bone. There is a central artery and a cage-like capillary network in the cartilage canal. The secondary center of ossification appears in the vascularized area of the cartilage. No intra-osseous intercommunications of the epiphyseal artery and nutritive artery exist in the epiphysis until the ossification of the epiphyseal plate.
