In the field of osteosynthesis, biomechanical research now decisively tends towards elastic and very versatile fixation systems. Consequently, a progressive abandonment of the concept of rigidity as an essential presupposition to obtain the reduction of fractures has occurred. Furthermore, from the analysis of recent studies, an exaltation of the biological potentiality of the bone tissue emerges as well as the repairing capacity of this tissue if it is properly treated. Particularly in hand surgery, an absolute respect of the bone tissue and of the other anatomic structures is a prerequisite for a functional renewal.
