During bone repair, what is the first structure to form at the site of a fracture after the initial hematoma?
Show answer and explanation
Correct answer: Fibrocartilaginous soft callus
Following a hematoma, capillaries grow into the area and phagocytes clean the debris. Fibroblasts and chondroblasts then create a fibrocartilaginous callus that 'splints' the broken bone ends before it is later replaced by bone.
