Fractures are broken bones. Most fractures occur from: * Sudden accelleration or decelleration -- car collisions, falls * Torsion -- sharp twists -- side car collisions etc. * Penetration trauma -- bullet wounds * Crushing or compression -- car acciddents, something falling on you * Repetitive Impact (jumping up and down for a few hours on a very hard surface can cause shin splints -- small, linear stress fractures).
They don't really occur in an exact spot it is always different. Sourcs: Science Teacher

Stress fractures
avulsed fragment occurs when bone fragments are pulled from their normal position by forceful muscle contractions or resistance from ligaments. Segmental fragmented positioning occurs if fractures in two adjacent areas occur
Compound fractures (now commonly called "open") break the skin, exposing bone and causing additional soft tissue injury and possible infection
The glass fractures outward from the point of impact. The particles that make up the glass break apart and move upward.

Compression fractures can be caused by osteoporosis, trauma inflicted on the back, and tumors that have started in the bone. Tumors that occur in the spine also cause compression fractures.
