Abstract

The device for the external (outside of the patent's body) fixation of bone fragments in the surgical treatment of fractures uses a unitary supporting bar (2) which, particularly in the case of shin-bone fractures, is positioned on the front side with a very close spacing from the bone and, for reasons of X-ray diagnosis, with a slight lateral displacement. A system of basic clamp assemblies (11), compound clamp assemblies (14) and paired clamp assemblies (12, 12a), and the thus facilitated surgical operation techniques, provide for mechanically highly stable fixation of the bone fragments being particularly careful as far as traumatizing is concerned, and being particularly favorable with respect to the psychic and physical restraint to the patient during the period in which the device is applied, and with respect to the cosmetic success upon convalescence. Due to a high degree of standardization, the system of the jaws combines cost-reducing manufacture with uncomplicated surgical operation techniques and with all possibilities for necessary corrective measures; the system favors both careful application and cosmetic success.
