The tibiofibular ligament is a connective tissue structure that connects the tibia and fibula, two bones in the lower leg. This ligament plays a crucial role in stabilizing the ankle joint and maintaining the alignment of these bones during movement. It is essential for activities such as walking, running, and jumping. There are two main types of tibiofibular ligaments: the anterior tibiofibular ligament and the posterior tibiofibular ligament. Both ligaments help to prevent excessive movement between the tibia and fibula, which can lead to injuries or conditions like syndesmosis. Proper function of these ligaments is vital for overall lower leg stability.
