[Bi-bone fractures of the leg. Indications and treatment]

After recalling some anatomical aspects (with particular reference to the diaphysary vascularization), the authors determine the limits of the conservative treatment of leg fractures, and then describe the surgical techniques they used in the different types of leg fracture. The authors point out the treatment of such fractures does not follow rigid patterns, but it should be chosen case by case after a careful evaluation of general and local factors.
