A sprained ankle can sometimes result in a bone chip, called an avulsion fracture. This is not a common result of a sprain.
The tibia is a large shin bone (as oppossed to the fibula which is it's smaller partner) which starts from the knee and ends at the ankle. A chip most likely means that your bone has been damaged and a small particle has broken off.
You should go back to the dentist and have them check it out. Sometimes a piece of bone will break off in the process of removing the tooth and it will poke through the gums and can be sharp. It is an easy process of removing the bone chip.
I'm pretty sure if you have a chip fracture it means that a piece of the bone has been chipped off. A hairline fracture means the bone is broken. However the break is very minor and most likely isn't broken all the way through.
It may not, necessarily, be a bone chip. Only an x-ray ordered by a doctor could confirm that. It is also possible that you just bruised the bone, this can leave a bump and a painful spot that will last for quite some time. I've done it, before, myself.

It is chip
Yes a chip (processor, RAM, BIOS, etc. are all chips) is considered a piece of hardware.
Avulsion fracture.
"Chip" can be a noun or a verb. As a noun, it refers to a small, thin piece that has been removed from something larger. As a verb, it means to break off a small piece from something.
A bone chip occurs in horses when they either bang against something and a sliver of bone pops off the main bone or they are worked harder than their bodies can handle and a bone chip breaks off. The location of the bone chip and any type of surgical history will factor into whether the horse can be ridden or not. You should have the horse Radiographed (X-Rays) and checked by a equine Veterinarian to see if the horse is sound for any type of riding.
