Final answer:
The most common complication of talus fx (fracture) is the rupture of the lateral ankle ligaments. Less common complications include eversion sprains of the ankle and Pott's fracture. Prompt medical attention is necessary for proper treatment.
Step-by-step explanation:
The most common complication of talus fx (fracture) is the rupture of the lateral ankle ligaments. Excess inversion or lateral movement of the talus bone can damage the anterior talofibular ligament and calcaneofibular ligament, which are the ligaments on the lateral side of the ankle. In severe cases, the forceful movement of the talus can also result in a fracture of the distal fibula.
On the other hand, less common complications include eversion sprains of the ankle, which involve stretching of the deltoid ligament on the medial side of the ankle. Eversion of the foot can lead to a Pott's fracture and dislocation of the ankle joint, causing the talus to move laterally and fracture the distal fibula.
It's important to seek medical attention for any suspected talus fracture to prevent further complications and ensure proper treatment.
