Final answer:
For fractures of the distal fibula and tibia, a Posterior Ankle Splint is commonly used to stabilize the bones and ankle joint, although the exact treatment depends on the nature and severity of the fracture.
Step-by-step explanation:
The question concerns what splint is used for fractures of the distal fibula and tibia. Fractures in this area require a splint that can provide stability and support to the injured region, often including the ankle. The distal fibula and tibia form part of the ankle joint, with the distal fibula articulating at the fibular notch of the tibia and its expanded distal end forming the lateral malleolus which, along with the medial malleolus of the tibia, helps to stabilize the talus.
Considering the anatomy and the need for immobilization, a common choice for splinting these fractures is the Posterior Ankle Splint or sometimes a Sugar Tong Splint, depending on the nature and severity of the fracture. The goal is to immobilize the ankle joint and the distal portions of both the tibia and fibula to prevent further injury and to allow for healing.
It is also important to note that treatment may vary based on the specifics of the injury, and therefore, medical assessment by a health professional is vital for determining the appropriate splint or additional forms of stabilization, such as a cast or orthopedic boot, if necessary.
