Most anatomy textbooks state that peroneus tertius arises from the distal third of the fibula and is inserted into the fifth metatarsal. In a study of one limb from each of 40 cadavers, peroneus tertius was absent in 2 limbs, and in 35 it arose from the lower middle quarter of the fibula. The origin was continuous with that of extensor digitorum longus in 33 limbs, and the length of the origin was correlated with the width of the tendon (r = 0.67). The tendon was single in 37 limbs and double in 1. Intertendinous connections between peroneus tertius and extensor digitorum longus were found in 6 limbs. The trapezoidal insertion of peroneus tertius into the fifth metatarsal was bifurcate in two cases and trifurcate in one. Our study suggested that the standard textbook descriptions of peroneus tertius need to be revised. © 1993 Wiley‐Liss, Inc.
