[A new open universal clamp for the external fixator tube system of the AO].
A new open universal clamp has been developed for the external fixator tube system of the ASIF. This new clamp is fully compatible with the previous system. All mechanical properties are at least comparable with those of the hitherto successful clamps, whereas in some cases they are even distinctly superior. The obvious advantages are: The clamp can also be pushed subsequently laterally onto the tubes and arbon fibre rods. The clamping plate for the Schanz screws can take 4-6 mm screws. It is thus possible to use this system alongside with the 4 mm system. The clamp replaces 2 of the previous clamps. An open tube-to-tube clamp can also be positioned. The clamps have been used with success and with full utilisation of all their advantages in their first clinical application.
