Preterm Rupture of the Membranes

Abstract

bone structure is directly related to the stresses imposed on bone.1 Later he proposed that all changes in the function of bones are attended by definite alterations in their internal architecture.2 This became known as Wolff's law-a law which can be restated in more general terms as: "The law of use and disuse." Use leads to hypertrophy, and disuse leads to atrophy.Bone mass and bone metabolism are relatively easy to measure, and Wolff's law as applied to bone has been repeatedly verified. It has been shown that both the action of gravity and the
