[Technique for shortening the radius].
In the idiopathic necrosis if the lunate, one of the most often used technics is the shortening of the radius. We describe here a method which allows a firm fixation by a concave plate, with an automatic compression due to the conicity of the screw-heads. The fitting is also automatically done by the means of two ancillary gauges: with the first one, the six screw-holes may be drilled at once in the right place: with the second one, the radius is tightly hold as the oblique resection is made up. Screwing the plate in a correct order, the shortening of the radius, the compression of the bony surfaces and the rigid osteosynthesis may be obtained in the same time.
