Final answer:
Wolff's Law concerns the relationship between bone form and function, stating that bones adapt to the stresses they encounter. During fracture repair, bone remodeling is a stage where Wolff's Law is exemplified, as the bone adapts to the stress environment it is subjected to.
Step-by-step explanation:
Wolff's Law describes the relationship between form and function in bone, specifically how bones adapt to the stresses placed upon them. According to Wolff's Law, bone in a healthy person or animal will adapt to the loads under which it is placed. If loading on a particular bone increases, the bone will remodel over time to become stronger to resist that sort of stress. The principle is observed in the way athletes' bones become denser with training, or conversely, how bed-ridden patients may experience bone loss due to lack of stress on their bones.
During bone repair, which is a natural process following a fracture, stages include the formation of a fracture hematoma, the formation of internal and external calli, the replacement of cartilage by trabecular bone, and finally, bone remodeling. This remodeling stage is directly related to Wolff's Law as it involves adapting to the stresses or lack thereof. Nutrition, exercise, hormones, and age can all affect the process of bone remodeling and repair.
