Relationship of the dorsalis pedis artery to the tarsal navicular (original) (raw)

The Journal of foot and ankle surgery : official publication of the American College of Foot and Ankle Surgeons

When undertaking surgical maneuvers about the midfoot, caution must be used to avoid injury to the dorsalis pedis artery, which courses along the dorsum of the foot on the dorsolateral aspect of the tarsal navicular. In an effort to better understand the relationship of the course of the dorsalis pedis artery relative to the tarsal navicular, 128 embalmed feet (31 [48.4%] female and 33 [51.6%] male cadavers aged 15 to 91 years) were measured. The dorsalis pedis artery was dissected from its origin to its termination (i.e., the first dorsal metatarsal artery and the deep plantar perforating artery), and the distance from the medial cortex of the navicular tuberosity to the medial margin of the artery and the location of the artery as a percentage of the medial-to-lateral width of the navicular were measured. In the male cadaver specimens, the distance from the navicular tuberosity to the dorsalis pedis was 23.75 ± 3.1 mm, the width of the navicular was 37.41 ± 5.0 mm, and the locatio...
