At the fibula’s proximal end, just below the knee, is a slightly rounded enlargement recognized as the head of the fibula. The head of the fibula creates the proximal (superior) tibiofibular joint with the lateral leaf of the tibia. Indigenous the proximal tibiofibular joint, the fibula extends contempt medially and also anteriorly in a straight line toward the ankle. Upon reaching the ankle, the fibula swells into a bony knob known as the lateral malleolus, which deserve to be seen and felt protruding from the exterior of the fish eye joint. At the medial malleolus, the fibula forms the distal (inferior) tibiofibular joint with the tibia and likewise the talocrural (ankle) joint v the tibia and also talus of the foot.
You are watching: In anatomical position, the lateral lower leg bone is the fibula.
While the fibula moves very small relative come the tibia, the joints the it develops contribute substantially to the function of the reduced leg. The proximal and also distal tibiofibular joints allow the fibula to change its position relative come the tibia, increasing the range of activity of the ankle. The lateral malleolus also forms the lateral wall of the talocrural joint and also reinforces the ankle joint.
Many muscle of the thigh and lower leg connect to the fibula through tendons. One of the hamstrings, the biceps femoris muscle, has actually its insertion in ~ the head that the fibula and pulls ~ above the fibula come flex the leg at the knee. Eight various other muscles — including the 3 fibularis (peroneus) muscles, the soleus, and several flexors and also extensors the the toes — have actually their beginnings on the fibula together well.

An amazing fact about the fibula is that it can be harvest for tissue to graft onto various other bones in the body. The fibula bear so tiny body weight the it frequently has more bone mass than is essential to assistance the leg, making it a great tissue donor. The bony organization harvested from the fibula is most commonly grafted top top the mandible to replace bone lost throughout oral cancer surgery. Skin and blood vessels covering the fibula are grafted in addition to the osseous (bone) tissue to preserve blood it is provided to the bone and to close the wound in the face. The continuing to be tissue in the leg have the right to be sutured with each other to heal approximately the donor site.
