Which workouts causes microfractures, so you can stretch and help increase height?

None: It sounds like you are looking for some type of exercise that will result in microfractures which then lead to lengthening of the bones and increased height? To my knowledge this is not possible. There is something called the ilizarov technique in which an external fixator is utilized for limb lengthening or straightening, but this is used for abnormal limb pathology.
