Prevention guide →How Bones Heal: Four Phases of Repair
Every fracture follows a predictable biological sequence. Understanding where you are in this process helps set realistic expectations for your recovery.
Inflammatory
Days 1 to 5Blood clot forms at the fracture site (hematoma). Inflammatory cells clean up damaged tissue. Swelling and pain peak during this window. Your body is laying the groundwork for repair.
Soft Callus
Weeks 1 to 3New blood vessels grow into the fracture gap. Cartilage-like tissue bridges the broken ends (soft callus). The bone starts to stabilize but is still fragile. No weight-bearing on most fractures during this phase.
Hard Callus
Weeks 3 to 12Soft callus converts to woven bone through mineralization. The fracture site becomes rigid. X-rays start showing visible healing. Gradual return to partial weight-bearing may begin under medical guidance.
Remodeling
Months 3 to 24Woven bone is replaced by stronger lamellar bone. The bone gradually returns to its original shape and strength. Full recovery can take 6 to 24 months depending on fracture type and location.
