Fibular

Fibular refers to the smaller of the two bones in the lower leg, the larger one being the tibia. The fibula is located on the outside of the leg and is generally thinner than the tibia. It plays a crucial role in stabilizing the ankle and supporting the muscles of the lower leg.

Anatomy of the Fibula

The fibula is a long, slender bone that runs parallel to the tibia. It has a slight curve and is roughly the same length as the tibia. The fibula is divided into three parts: the head, the body (or shaft), and the lateral malleolus.

Head of the Fibula

The head of the fibula is the topmost part of the bone. It is rounded and connects to the tibia below the knee joint. The head of the fibula does not bear any weight.

Body of the Fibula

The body or shaft of the fibula is long and thin. It is slightly curved and has a rough surface, which provides attachment points for muscles and ligaments.

Lateral Malleolus

The lateral malleolus is the lower end of the fibula. It forms the outer part of the ankle joint and provides stability to the ankle.

Function of the Fibula

The fibula serves several important functions in the body. It provides support and stability to the tibia, helps to bear the body's weight, and provides attachment points for muscles and ligaments. The fibula also plays a role in the formation of the ankle joint.

Related Conditions

Several medical conditions can affect the fibula, including fractures, stress fractures, and shin splints. Treatment for these conditions can vary depending on the severity of the injury and the patient's overall health.
