Answer. It is also known as Wolffs law of bone transformation.

• In the year 1870, Julius Wolf explained the reason for the arrangement of trabecular pattern. He attributed the trabecular arrangement pattern to functional stresses.
• A change in the magnitude of force could produce a marked change in the internal architecture and external form of the bone. These changes are accomplished by means of selective resorption of existing bone and resorption of new bone.
• These remodeling changes can take place in the compact bone under periosteum or in trabecular pattern of cancellous bone or on the walls of marrow spaces.
• Increase in function leads to an increase in density of bony trabeculae, while lack of function leads to a decrease in trabecular density. This is called the “Wolffs law.
• Due to such transformation, not only the quantity of bone tissue is kept minimum that would be needed for functional requirements, but also its structure is such that it is best suited for the forces exerted on it.
