The fibula does not carry any significant load (weight) of the body. It extends past the lower end of the tibia and forms the outer part of the ankle providing stability to this joint. It has grooves(a depression) for certain ligaments which gives them leverage and multiplies the muscle force. It provides attachment points for the following ...
The fibularis brevis (bottom-most label) is a muscle of the lower leg and aids in plantar flexion and eversion of the foot. The fibularis brevis arises from the lower two-thirds of the lateral, or outward, surface of the fibula (inward in relation to the fibularis longus) and from the connective tissue between it and the muscles on the front and back of the leg.
The fibularis tertius arises from the lower third of the front surface of the fibula, the lower part of the interosseous membrane, and septum, or connective tissue, between it and the fibularis brevis. [1] The septum is sometimes called the intermuscular septum of Otto.

The fibularis muscles are highly variable. Several variants are occasionally present, including the peroneus digiti minimi and the peroneus quartus. [2] The quartus is more closely associated with the tendons of the extensor digitorum longus and may send a small tendon to the fifth (or little) toe.
In human anatomy, the fibularis longus (also known as peroneus longus) is a superficial muscle in the lateral compartment of the leg.It acts to tilt the sole of the foot away from the midline of the body and to extend the foot downward away from the body (plantar flexion) at the ankle.
Fibular hemimelia or longitudinal fibular deficiency is "the congenital absence of the fibula and it is the most common congenital absence of long bone of the extremities." [1] [2] It is the shortening of the fibula at birth, or the complete lack thereof. Fibular hemimelia often causes severe knee instability due to deficiencies of the ligaments.
