Acute Injuries of the Leg, Ankle, and Foot T2 Pediatric Practice: Sports Medicine YR 2009 FD 2009 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-149677-3 LK accesspediatrics.mhmedical.com/content.aspx?aid=6980338 RD 2024/04/19 AB Tibia and fibula are connected by proximal and distal tibiofibular articulations and by an interosseous membrane between the bones through the entire length. The relevant anatomy of the leg is depicted in Figures 28-1, 28-2, 28-3, and 28-4. One head of gastrocnemius muscle arises from the medial and the other from the lateral condyle of the femur. Distally gastrocnemius inserts into the tendon of the Achilles. Achilles tendon is a common tendon formed by the gastrocnemius and soleus muscles which inserts into the posterior calcaneus. Peroneus longus arises from the lateral surface of the fibula and is inserted into the base of the first metatarsal and medial cuneiform. The peroneus brevis originates from the lower two-thirds of the lateral surface of the fibula and is inserted into the base of the fifth metatarsal.
