Final answer:
Fracture of the tibia and fibula are often associated with vascular injury as a result of the distorted positions of the limb following injury.
Step-by-step explanation:
Fracture of the tibia and fibula are often associated with A. vascular injury as a result of the distorted positions of the limb following injury.
Above the ankle, the distal ends of the tibia and fibula are united by a strong syndesmosis formed by the interosseous membrane and ligaments at the distal tibiofibular joint. These connections prevent separation between the distal ends of the tibia and fibula and maintain the talus locked into position between the medial malleolus and lateral malleolus. Injuries that produce a lateral twisting of the leg on top of the planted foot can result in stretching or tearing of the tibiofibular ligaments, producing a syndesmotic ankle sprain or "high ankle sprain."
