[Observation of the metatarsal nutrient artery]
OBJECTIVE: To observe the origin, course and diameter of the metatarsal nutrient artery. METHODS: The metatarsaL nutrient in 90 feet, ranging in age from newborn to 87 years, were studied by perfusion method. The origin, course and diameter of these arteries were observed and measured. RESULTS: The diameter of the metatarsal nutrient artery was 0.24 approximate, equals 0.30 mm. The nutrient arteries of the first metatarsal bone originated from the deep plantar branch and the first metatarsal plantar artery in 59.6% of specimens, while the nutrient arteries of the other metatarsal bones mainly originate from the plantar metatarsal arteries, the plantar arch and its perfora-ting branches. The diaphysial nutrient foramina were situated in the middle third of the shaft over 90% of specimens. CONCLUSION: The metatarsal nutrient artery showes practical significance in clinic.
