Cotton Test | Syndesmosis Injury | Ankle Assessment<\/h2>\nThe syndesmosis is the interosseous membrane that connects the tibia to the fibula. A syndesmosis rupture can result from both inversion trauma and, more importantly, from trauma to the ankle joint in external rotation and dorsiflexion. According to the guideline on ankle injuries of the Dutch Association of Physical Therapists, KNGF, the incidence of syndesmosis injury among all ankle injuries is approximately 1%.\nThe Cotton test is designed to test for syndesmosis instability caused by the separation of the tibia and fibula, which are held together by four different ligaments.
