The Hueter-Volkmann law of epiphyseal pressures describes an inverse relationship between static compressive forces parallel to the axis of epiphyseal growth and the rate of growth of that cartilage. Studies of histological sections of the epiphyseal plate of the fourth metatarsals of (a) control, (b) bipedal and (c) bipedal rats with amputation of the fifth metatarsal show that dynamic compressive forces can stimulate epiphyseal cartilage growth. Within certain parameters, both the relief and increase of dynamic compression accelerate epiphyseal growth. It is the amount and kind of loading that are important factors to accelerate epiphyseal growth.
