为跖骨头缺血性坏死显微外科修复提供解剖学依据。方法４０侧经动脉内灌注红乳胶成尸下肢标本，观测内侧楔骨、骰骨背侧骨膜血管的来源、走行、分支及吻合。结果内侧楔骨血供来自跗内侧动脉、内踝前动脉、足底内侧动脉分支。动脉终支以不同出现率，沿第一跖骨内侧至其中段穿入并与跖底动脉相吻合。跗外侧动脉分出骰骨骨膜血管，并分出第２～４跖背动脉，在跖骨颈处分出穿支与跖底动脉相吻合。结论以上述血管为蒂设计的内侧楔骨、骰骨骨膜瓣或骨膜软骨瓣，选择其中供区逆行修复跖骨头缺血性坏死。
Provide anatomical basis for microsurgical repair of metatarsal head ischemic necrosis. [Methods] 40 cases were injected with red latex into corpse lower limbs via intra-arterial injection. The origin, course, branch and anastomosis of medial cuneus and dorsal periosteal blood vessels were observed. Results The medial cuneus was derived from the medial malleolus, the anterior malleolus and the medial plantar artery. End arteries at different rates occur along the medial side of the first metatarsal to its midline and match the plantar plantar artery.跗 lateral arteries divide the cuboid periosteal blood vessels, and the first 2 to 4 dorsal metacarpophalangeal artery, metatarsal neck at the branch and the plantar artery coincide. Conclusions The medial wedge, cuboid periosteal flap or periosteal cartilage flap pedicled with the above vascular design were selected for retrograde repair of metatarsal head avascular necrosis.
