本研究通过动脉灌注,对50侧不同年龄(4~87岁)尸体胫骨的血液供应进行了研究。胫骨的动脉主要来自胫前、后动脉和腓动脉的分支,附加的有膝下动脉、膝中动脉和膝降动脉髌下支。在胫骨非关节面区域的周围,组成一个连续的骨膜动脉网。节段性骨膜动脉弓发升、降支沿胫骨前缘、内侧缘和外侧缘下1/3,上、下连成纵链。骺-干骺区的血液供应丰富,由来自周围穿入的骺-干骺血管和滋养动脉分布。随骺板融合,骺血管和干骺-滋养血管间建立广泛的吻合。骨髓和皮质内2/3或3/4由滋养动脉供应。皮质外1/3或1/4由骨膜血管供应。皮质纵、横的毛细血管相互吻合丰富,并分别与骨膜和骨内膜的毛细血管网相连接,其血流方向可随生理状态而改变。本文对胫骨动脉分布的临床意义作了简要讨论。
In this study, arterial perfusion, 50 sides of different ages (4 to 87 years old) of the tibia of the blood supply were studied. The tibial arteries originate mainly from the anterior tibial and posterior arteries and the branches of the peroneal artery, with the addition of the inferior arteries, the middle of the knee, and the inferior descending knee of the knee. Around the non-articular area of the tibia, form a continuous network of periosteal arteries. Segment of the periosteal artery bow rise, descending branch along the anterior tibia, medial and lateral margin of the lower 1/3, up, down into the longitudinal chain. Epiphyseal - metaphyseal area of the blood supply is rich, from the penetration of the surrounding epiphyseal - metaphyseal vessels and nourish the artery distribution. With the epiphyseal plate fusion, epiphyseal blood vessels and metaphyseal - nourish the blood vessels to establish a wide range of anastomosis. Two-thirds or three-quarters of the marrow and cortex are supplied by the nourishing artery. 1/3 or 1/4 of the cortex is supplied by the periosteum. Cortical longitudinal and transverse capillary anastomosis plentiful, and were connected with the periosteum and endocervical capillary network, the blood flow direction can be changed with the physiological state. This article gives a brief discussion of the clinical significance of tibial artery distribution.
