Q

A 10 year old boy jumped off the roof of their house, he was still able to walk, but felt pain everytime he put weight on his right heel, upon physical examination, the aspect of the heel inferior to the tibia was tender to pressure. Which bone was most likely fractured

A. Fibula
B. Calcaneus
C. Tibia
D. Cuboid
E. Navicular
A

B. Calcaneous

The calcaneus is the most frequently broken of the tarsal bones. The weight of the body is transmitted down the tibia and onto the talus, which acts as a wedge cracking the calcaneus inferiorly.
