Question

Explain the process of bone remodelling using examples of a tennis player and an archer. In
your answer, refer to Wolff’s law

Answer 1

Dear student,

Wolff's law was suggested by Julius Wolff.

This law states that the bones in a healthy person adapt to the loads under which it has been placed i.e., if load on a particular bone increases, it remodels itself and becomes stronger.

The trabeculae of the bone undergoes adaptive changes followed by changes in the external cortical portion of the bone.

Example :

*In case of tennis players , one arm is used more often than the other arm. So, the racquet holding arm becomes much stronger as they are placed under higher stress than the other arm. (High stress occurs during external shoulder rotation and this can result in twisted bone profile.

*Similarly, the same effects are seen in archer, in whom one hand is stressed more than the other hand.
