What you’ll learn

Break, bleed, and first respondersDescribe hematoma, inflammation, and why immobilization matters.Fractures bleed and clot; inflammation clears and signals. Stability protects the soft repair that comes next.
Soft callus to hard callusSequence soft then hard callus and the role of blood supply.A soft bridge restores continuity; mineralization stiffens it. Blood flow and biology set the pace.
Remodeling and getting strong againExplain remodeling under load, age differences, and fixation.Months of remodeling refine strength. Kids often correct more. Hardware holds geometry while cells heal.

Questions this course answers

Order the early fracture response

Break and bleed, clot, inflammatory clean-up, then transition toward soft callus builders.

Match each healing stage to what it mainly does

Soft tissue bridges first, then mineral hardens it; blood flow and stability make both possible.

Fill the remodeling idea

Remodeling replaces woven callus with more organized bone shaped by mechanical use.
