Stress fractures occur when bone is subjected to loads exceeding its normal healing capacity, leading to micro-fractures that fail to heal with insufficient recovery time.

“a stress fracture is something that occurs slowly so a stress fracture at Baseline potentially normal bone with a substantial load to that bone that is in excess of what the normal healing capacity is of that bone that is bone constantly remodels every time we put stress on it the micro architecture is changing there's small tiny micro fractures that occur from normal weight bearing”
