Question

The diagnosis was that the extreme eversion and plantar flexion that occurred during the fall resulted in a severe dislocation of the ankle joint proper (talocrural joint) and spraining of the ankle at the calcaneofibular ligament. The surgeon stated that she would perform a reduction of the dislocation and then attempt to repair the injured ligament using arthroscopy. Which bones would have been dislocated?

a. Calcaneus, talus, and tibia
b. Talus, tibia and fibula
c. Talus and fibula
d. Calcaneus and fibula
e. Calcaneus and talus

Answer 1

b. Talus, tibia and fibula

Step-by-step explanation:

In this scenario, the diagnosis was that the extreme eversion and plantar flexion that occurred during the fall resulted in a severe dislocation of the ankle joint proper (talocrural joint) and spraining of the ankle at the calcaneofibular ligament. The surgeon stated that she would perform a reduction of the dislocation and then attempt to repair the injured ligament using arthroscopy. Thus, the bones which would have been dislocated are talus, tibia and fibula.

Generally, when the anterior cruciate ligament which is one of the key ligaments that stabilizes the knee joint is damaged, a surgeon would have to perform a reconstruction. The tibia bone is a shinbone and it is connected by the anterior cruciate ligament with the femur (thighbone).

Basically, the ankle joint is made up of three (3) main bones and these are the tibia, talus and fibula, thus, they would all need to be repaired by the surgeon through arthroscopy.
