Which stage occurs around 5-10 days after a fracture?

The stage that occurs around 5-10 days after a fracture is callus formation. During this stage, the body begins the healing process by forming a soft callus made of collagen and cartilage at the fracture site. This occurs after the initial hematoma and inflammatory response, where a blood clot forms, and inflammatory cells clean up the area and prepare it for healing.

In the callus formation stage, osteoblasts (bone-forming cells) start to lay down new bone tissue, transforming the soft callus into a hard callus, which provides stability to the fracture site. This is a crucial step in the repair process, allowing for the subsequent formation of a more mature bone structure and ultimately leading to consolidation. The timeframe of 5-10 days aligns with the typical progression of healing, where soft tissue repairs begin to support the fractured bone, setting the stage for further healing and remodeling.
