Biological Bone Healing Phases
Phase 1: Inflammatory Hematoma (Days 1–7)
Vascular disruption, cytokine signaling, initial fibrin clot formation.
Phase 2: Fibrocartilaginous Soft Callus (Weeks 2–3)
Chondrocyte collagen production, bridging fracture gap with soft tissue.
Phase 3: Bony Hard Callus (Weeks 4–8)
Endochondral ossification converts soft callus to woven trabecular bone.
Phase 4: Osteoclastic Remodeling (Months 3–12)
Wolff's Law realignment, lamellar cortical bone reconstruction.
Orthopedic Protocol: Cast immobilization (6-8 wks), non-weight bearing, radiographic alignment check.
