Anterior tibiofibular ligament
Located deep in the leg near the ankle is the anterior tibiofibular ligament. This ligament holds the tibia and fibula together. This is a very common place for people to injure themselves. When doctors study this ligament in a patient they often use a stress test to help to determine the health of the ligament. However, it can be difficult for doctors to get a true measurement in this way because people often stiffen their ankles during the stress test. There are several different types of tests that doctors perform to diagnose problems with this ligament. One of them is the inversion stress test. This is where the knee is held at a 90 degree angle and and the heel is pushed from below with one hand and another hand is needed to hold the lower leg. Another is the external rotation test where the doctor rotates the foot. There is also a squeeze test where a doctor squeezes the ankle bones firmly. The anterior tibiofibular ligament is located close to the ankle and hold together two very important leg bones. It can be injured easily and there are tests to check the health of the ligament.
