  • Device for externally securing fractures
    Patent number: 5827284
    Abstract: A device for securing fractures, the device having at least one traction/compression rod, a plurality of bone screws and clamps wherein the clamps have a threaded tubular supporting member. The supporting member is pierced by two diametric, axially staggered through-holes through which the traction/compression rod or the bone screw passes and is therein clamped. The bone screw is adjustably clamped by a supporting ring with a conical outer surface and a mating ring thereon with a conical inner surface and a clamping ring. The traction/compression rod is held only by a clamping ring and thereby provides a particularly economical system which is highly adaptable, easy to use, and particularly suitable for use by paramedical staff.
