Peroneus tertius (PT) and extensor digitorum longus (EDL), are muscles of the anterior compartment of the leg, important for the bipedal gait in humans. They are used as anatomical boundaries during arthroscopy of the ankle joint and widely used for soft tissue replacement surgeries. PT is implicated in the pathophysiology of Jones fracture of the fifth metatarsal bone. It was the objective of this project to study the characteristics of PT and EDL in cadaveric specimens. The PT and EDL muscles of the leg in 25 lower limb specimens were examined for features with regard to muscle length, tendon length, mid circumference, origin and insertion. A single muscle belly replacing PT and EDL was observed in 7 specimens giving rise to 5 tendons which had distal attachments to the lateral 4 digits
