Why does bone density adaptation (Wolff's Law) following femur fracture repair prioritize new bone deposition along stress lines, rather than uniform callus distribution?

💡 Explanation

Bone remodeling favors stress lines because the mechanotransduction process during remodeling stimulates osteoblast activity preferentially in regions experiencing higher mechanical load; therefore, directed deposition optimizes structural integrity rather than spreading resources diffusely because uniform distribution would neglect efficient load transfer pathways.
