GROSS ANATOMY

Detailed explanation-1: -The fibular notch of the tibia is an indentation at the inferior portion of the tibia where it articulates with the fibula to form the inferior tibiofibular articulation.

Detailed explanation-2: -The fibula acts as an proximal attachment for the following muscles: Extensor digitorum longus: Superior 3/4 of medial border. Extensor hallucis longus: Middle of anterior surface. Fibularis tertius: Inferior 1/3 of anterior surface.

Detailed explanation-3: -Like other long bones, the fibula has a proximal end (with a head and neck), a shaft, and a distal end. The fibula and tibia run parallel to each other in the leg and are similar in length but the fibula is much thinner than the tibia. This is indicative of the weight-bearing contributions of each bone.

Detailed explanation-4: -English. The posterior ligament of the head of the fibula is a single thick and broad band, which passes obliquely upward from the back of the head of the fibula to the back of the lateral condyle of the tibia. It is covered by the tendon of the Popliteus.
