What is the syndesmosis?
A movable articulation formed at the distal tibiofibular articulation
What is the Mechanism of injury for the syndesmosis?

What is a deltoid ligament sprain?
Done with excessive eversion and takes longer to heal there’s pain over medial aespect of ankle
What test is done to test medial ligament sprain?
The eversion stress test
