The fibula is a bone found in the human body, specifically in the lower leg. It is one of two bones that make up the lower leg, the other being the tibia. The fibula is located on the outer side of the leg, running parallel to the tibia, but it is considerably slimmer and smaller in size compared to its counterpart.
Anatomically, the fibula extends from the knee joint to the ankle joint, providing support and stability to the leg when walking, running, or engaging in various physical activities. It is non-weight bearing, which means it doesn't bear as much load as the tibia. However, it plays crucial roles in muscle attachment and helping to maintain the shape and structure of the leg.
The fibula has distinct features including a head, neck, body, and lateral malleolus. The head of the fibula articulates with the tibia, forming the syndesmosis joint. The neck connects the head to the body, which runs along the length of the leg. At the ankle, the fibula expands into a bony prominence called the lateral malleolus, which helps to stabilize the joint.
Injuries to the fibula can occur, such as fractures or sprains, which can lead to pain, swelling, and difficulty walking. Treatment usually involves immobilization, rest, and potentially surgical intervention depending on the severity of the injury.
Overall, the fibula is an important bone in the lower leg, contributing to overall structural support and functioning of the leg during movement.
