Fractures, Stress

Medical Definition:	Fractures due to the strain caused by repetitive exercise. They are thought to arise from a combination of muscle fatigue and bone failure, and occur in situations where bone remodeling predominates over repair. The classical stress fracture is the march fracture of military personnel, in which the metatarsal undergoes repeated stress during marching. The most common sites of stress fractures are the metatarsus, fibula, tibia, and femoral neck.
Guide Notes:	fract caused by repetitive strain; X ref FATIGUE FRACTURES refers to bone fractures: do not use for metal fatigue as in fatigue fract of amalgams, nails, screw plates, etc (index under STRESS, MECHANICAL); coord IM with specific organ /inj or organ/fract
