What is the primary function of the fibula?

The primary function of the fibula is to stabilize the ankle joint. The fibula is a long and slender bone located on the lateral side of the lower leg, parallel to the tibia. While it does not bear significant weight compared to the tibia, it plays a crucial role in providing lateral support to the ankle. This stabilization is important for maintaining balance and preventing excessive movement that could lead to injuries.

The fibula also serves as an attachment point for several muscles, which can assist with movements of the foot and ankle. However, its main function centers around the stability of the ankle joint, as it helps to maintain the integrity of the joint during various activities such as standing, walking, and running. Understanding the role of the fibula in stabilizing the ankle is vital for those studying orthopedic technology as it relates to injury prevention and rehabilitation.
