Partial Tear – Anterior Talo-Fibular Ligament
The lateral ligaments of the ankle consist of the anterior and posterior talo-fibular and the calcaneo-fibular ligaments. These can be torn on an inversion injury. The anterior talo-fibular ligament is weakest and is the first to tear. Shown below is a partial tear of this ligament due to an inversion injury sustained whilst playing badminton (attempting to return a backhand whilst off-balance). The calcaneo-fibular and posterior talo-fibular ligaments are intact.
