Abstract
BACKGROUND: The insertion of peroneus longus is traditionally described to the plantar surface of the 1st cuneiform and 1st metatarsal. It is thought to be the main contributor to the plantarflexed first ray seen in cavus feet. METHODS: We studied the insertion of peroneus longus in 26 feet from 14 adult cadavers. The insertional points, presence of sesamoid bone and variations in insertion were noted. RESULTS: The main insertion was to the base of the 1st metatarsal and the medial cuneiform in the majority of feet but variations were observed. A sesamoid bone was present within the tendon under the cuboid in 16 feet, 12 of which had additional lateral insertion bands. CONCLUSIONS: Variations in the insertion of peroneus longus were found and we have described two new lateral bands.
