Head of fibula
Other Terms: Head of fibula, Proximal end of fibula, Upper end of fibula, Caput fibulae
The head is the moderately expanded proximal end of the fibula. It serves as the attachment site for the extensor digitorum longus, peroneus longus, soleus, and biceps femoris muscles. The fibular collateral and tibiofibular capsular ligaments also attach here. This landmark is easily palpated.
Head, or its Latin equivalent caput, refers to a rounded extremity on bone.
