After the formation of a hematoma, the next step in the repair of a simple fracture is the formation of a fibrocartilaginous callus. This callus is made up of fibroblasts, chondroblasts, and osteogenic cells that produce collagen fibers, cartilage, and woven bone to create a "soft" callus that connects the broken ends of the bone. Eventually, the callus will be replaced with a bony callus through the process of endochondral ossification. Inflammation and bone remodeling occur later in the healing process.
