Bones regenerate through a highly coordinated repair process after injury.

When a fracture occurs, blood vessels rupture and form a clot,

creating a temporary matrix.

Within days, specialized cells called osteoblasts begin producing new bone tissue,

while cartilage forms a soft callus to stabilize the area.

Over the next few weeks, this callus hardens into woven bone,

restoring structural integrity.

Remodeling then begins, where osteoclasts break down excess material

and reshape the bone into its original form.

This entire process takes six to eight weeks for initial healing,

with full-strength recovery continuing for months or even years.
