Abstract

Ankle fractures are the most common type of foot and ankle fracture injury. Several types of fractures occur in the ankle structures (medial malleolus, lateral malleolus, posterior malleolus, and Chaput’s tubercle) with various mechanisms and extent of fracture force. Moreover, fractures can be accompanied by other injuries, such as distal tibiofibular syndesmotic injury, medial deltoid ligament rupture, and lateral ligament complex rupture. Ankle dislocation can be accompanied when an injury is caused by a greater fracture force. Non-surgical treatments or combined surgeries may be performed depending on the mechanism and fracture type. Generally, a stable fracture maintaining anatomical reduction is treated conservatively, but surgical treatment is performed when this is not the case. Furthermore, surgeries for stable fractures can be offered when the patients demand early weight bearing due to their occupation, age, and performance state. Restoring the ankle mortise in its anatomical shape before the injury and starting early rehabilitation for functional recovery simultaneously until a union is achieved is important. Traumatic arthritis can occur if the treatment focuses only on fractures and neglects ligament injuries, such as distal tibiofibular syndesmotic injury and medial deltoid ligament rupture. Shortening, angular deformation, and rotational deformation of the fibular promote the progression of traumatic ankle arthritis in the long term, which may further cause chronic ankle pain. An overlooked displaced posterior malleolus fracture also causes traumatic arthritis through anteroposterior instability of the ankle joint.
