目的：弄清第１跖趾关节和趾趾间关节的血供。方法：正常动脉灌注红色乳胶成人足２４只，观测第１跖趾关节和趾趾间关节的结构，各关节血管及神经的分布情况。结果：第１跖趾关节的动脉关节支来源于第１跖背动脉、第１跖底动脉以及它们的分支趾趾背动脉、趾底动脉和横动脉。它有背胫侧、背腓侧、跖胫侧、跖腓侧、关节前和关节后６部分关节支。趾趾间关节的动脉关节支来源于趾趾背动脉、趾底动脉和横动脉。它有背胫侧、背腓侧、跖胫侧、跖腓侧和关节后５部分关节支。结论：第１跖趾关节和趾趾间关节的血供丰富，但跖侧多于背侧，腓侧多于胫侧，故这些部位手术时，切口尽可能在背胫侧，以减少对关节血供的影响。
Objective: To clarify the first metatarsophalangeal joint and toe interphalangeal joint blood supply. Methods: Twenty-four adults with normal arterial infusions of red latex were observed. The structures of the first metatarsophalangeal joint and toe-toe-toe joint and the distribution of blood vessels and nerves in each joint were observed. RESULTS: Arterial branch of the first metatarsophalangeal joint originated from the first dorsal metatarsal artery, the first plantar and inferior petrosal artery, and their branches toe dorsal artery, toe artery and transverse artery. It has dorsal, dorsiflexion, tarsal metatarsal, plantar fibular, anterior and posterior joint of 6 parts of the articular branch. Arterial branches of the interdigital toe joint originate from the toe toe dorsal artery, the toe-toe artery and the popliteal transverse artery. It has a dorsal tibial, dorsal and peroneal, tarsal metatarsal, tarsal metatarsal and 5 joints after the articular branch. Conclusion: The first metatarsophalangeal joint and toe-toe interphalangeal joint blood supply, but the plantar side more than the dorsal side, the fibular side more than the tibia, so these parts of the surgery, incision as possible in the dorsovera to reduce the right Effect of joint blood supply.
