Knowledge of the anatomical pattern of dorsalis pedis artery is important during evaluation of peripheral
circulation, peripheral vascular disease, microvascular flap, ankle and foot surgery. Reports from other
populations on the pattern show wide disparity suggesting ethnic and geographical differences. Data
from black African populations is scanty. This study therefore examined the anatomical pattern of dorsalis
pedis artery among adult black Kenyans. The cadaveric dissection study on 30 formalin fixed specimens
evaluated the origin, position, course and branching pattern of the dorsalis pedis artery. The data were
analysed using SPSS for means, frequency and standard deviation. Student t – test was used to determine
side differences at 95% confidence interval where P – Value of <5% was taken as statistically significant.
The artery was consistently present, as a continuation of the anterior tibial artery. It ran 4.6 mm ± 2.1
mm from the medial malleolus, and about 2.5 ± 0.3mm from the medial border of the base of the first
metatarsal bone. The mean was 4.76 mm on the right, and 4.56 mm on the left. The difference was
statistically significant (P<0.05). Three branching patterns were observed. The conventional pattern was
observed in only 47% of cases. The extensor hallucis longus tendon most frequently crossed the artery
above the ankle joint. There were no cases of crossing below the ankle. These observations reveal that
the dorsalis pedis artery is consistently present, high, relatively medialised, and displays an atypical
branching pattern. Due care should be taken during surgery. Preoperative ultrasound evaluation is
