Wolff's law

Dr Balint Botz et al.

Wolff's law summarizes the dynamic nature of the 3D microarchitecture of bone. Mechanical forces (or the lack of them) dynamically alter the thickness of cortical bone and the thickness and orientation of trabeculae. 

Lack of sufficient mechanical loading (e.g. bed rest) results in resorption and thinning of trabeculae while increased mechanical stress (e.g. physical exercise) facilitates bone formation along the lines of stress. This adaptive mechanism is a safeguard against overuse injuries such as stress fractures. This trabecular bone formation along lines of stress is best seen on imaging in the femoral shaft and calcaneus 1

History and etymology

It is named after Julius Wolff (1836-1902), a German anatomist and surgeon 2.
