The formation of the bony callus in fracture repair is followed by remodeling. During remodeling, the bony callus is gradually replaced by mature bone tissue, restoring the shape and strength of the fractured bone. This process can take several weeks to months to complete.
The order of stages of bone fracture healing is formation of a hematoma, formation of a fibrocartilaginous callus, formation of a bony callus, and, finally, bone remodeling.
When a bone heals from a fracture, the body initiates a complex healing process that typically occurs in three stages: inflammation, repair, and remodeling. Initially, a hematoma forms at the fracture site, followed by the formation of a soft callus made of cartilage and connective tissue. This is then replaced by a hard callus of new bone tissue, which eventually undergoes remodeling to restore the bone's original shape and strength. Throughout this process, various cells, including osteoblasts and osteoclasts, play crucial roles in bone formation and resorption.
The first stage in healing a bone fracture is the inflammatory stage which can last for a few hours or a few days. The second stage is the repair stage and the third stage is the late remodeling stage. The final stage is rehabilitation.
The healing process typically begins as soon as the fracture occurs. The body responds by forming a blood clot or callus at the site of the fracture to stabilize the bone and initiate the repair process. Depending on the severity of the fracture, visible signs of healing, such as bone remodeling and callus formation, may start to occur within a few weeks.
Reparitive phase - 2nd phase of bone healing

Fracture repair involves several key steps: First, a hematoma forms at the fracture site, providing a scaffold for new tissue. Next, inflammatory cells clear debris, and a soft callus made of cartilage begins to form, stabilizing the fracture. This is followed by the conversion of the soft callus into a hard callus through ossification, where bone replaces cartilage. Finally, the bone undergoes remodeling, where excess material is removed, and the bone regains its original shape and strength.
Following the formation of the bony callus in fracture repair, the next phase involves the remodeling of the callus into a stronger, more organized bone structure. This process can take several months to years, during which the callus is gradually replaced by compact bone, and the bone returns to its original shape and strength. Additionally, the surrounding muscles and tissues may also adapt to support the healed bone. Overall, the remodeling phase is crucial for restoring the functionality and integrity of the bone.
Infection can interfere with bone repair. This risk is greater in the case of a compound fracture (a bone fracture causing an open wound) where ideal conditions are present for severe streptococcal and staphylococcal infections
When a bone breaks, the body initiates a process called bone remodeling. Osteoclasts are cells that break down and remove the damaged bone tissue, while osteoblasts come in to build new bone tissue to repair the fracture. This process helps to remodel and strengthen the bone at the site of the break.
