Healing a broken bone is a lengthy and awkward process. The current, most effective way to repair bone tissue is to ensure correct positioning of the bone during healing, usually by use of a plaster cast or splint. With the average time to repair bone fractures being around six weeks this is a slow process and one that can often be uncomfortable for the patient.
