[Bilateral fractures of the proximal end of the radius].

Authors describe in connection with two cases of their own the vulnerability of the elbow joint originating from the physiological valgus position of this joint, i.e. the effect of the so-called "valgus stress". In the available literature no description of bilateral synchronous fracture of the radial head was found. They think, because of the bilateral injury, the correct operative therapy with the aim of reaching whole function, the stable osteosynthesis promising good result even in the fracture of the radial neck with major dislocation allowing also an early functional treatment, important.
