Document Summary

This is because the bone is naturally plastic (but this is difficult to explain to juries) The plasticity of younger bones is greater than that of adults. Following a fracture, blood from the broken vessels in the periosteum and marrow infiltrate the fracture site forming a blood clot. The blood clot is invaded by fibroblasts, connective tissue cells from the periosteum; the fibroblasts produce and secrete collagen fibers to form a mass of cells and fibers (callus) that bridges the broken ends. The callus is then invaded by osteoblasts from the periosteium and convert the callus into bone which brings the ends together. Gradually the bone matures from the woven state to organized trabecular bone and it could approach its original state depending on the severity of the break and age of the person. There is typically a bump formed in the area that the fracture occurred.
