Bone healing

Fracture healing coordinates blood supply, inflammation, tissue formation and remodeling. Mechanical stability and biological environment influence whether bone restores continuity.

Original schematic relationship map for this topic; relationships are organized for study, not intended as an anatomical depiction or a diagnostic algorithm.

Concept 01

Inflammatory phase

A fracture disrupts local vessels and creates a hematoma; inflammatory cells and signaling molecules recruit repair cells.

Concept 02

Soft and hard callus

In many secondary-healing settings, fibrocartilaginous callus is gradually replaced by woven bone as repair progresses.

Concept 03

Remodeling

Woven bone is progressively remodeled into stronger organized bone according to mechanical demands.

Concept 04

Healing modifiers

Severe tissue damage, poor perfusion, infection, smoking and some systemic disorders may impair healing; fixation changes local mechanical conditions.

Education / safety note: Primary bone healing under rigid fixation differs from the classic callus sequence. Clinical management requires imaging and orthopedic supervision.
