A stress fracture is one type of incomplete fracture in bones. It is caused by "unusual or repeated stress" and also heavy continuous weight on the ankle or leg. This is in contrast to other types of fractures, which are usually characterized by a solitary, severe impact.
It could be described as a very small sliver or crack in the bone; this is why it is sometimes dubbed "hairline fracture". It typically occurs in weight-bearing bones, such as the tibia (bone of the lower leg), metatarsals (bones of the foot), and less commonly, the femur.
It is a common sports injury, and most cases are associated with athletics.

Famous quotes containing the word stress:
“While ... we cannot and must not hide our concern for grave world dangers, and while, at the same time, we cannot build walls around ourselves and hide our heads in the sand, we must go forward with all our strength to stress and to strive for international peace. In this effort America must and will protect herself.”
—Franklin D. Roosevelt (1882–1945)
