Distal radius fracture fixation for the intramedullary nail

摘要

(57) [summary] (modified with) [purpose] is not cause any reduction when fixed with reference to the Kirschner wire, etc., to provide a novel fixed nails that can be fixed with a good limb position. Intramedullary nail CONSTITUTION] the fixing member is proximal seven two Hosohaba plate-like metal material have been bonded, the two main side 8 _1, 8 ₂ in pine needles shaped opening at a small angle and it is formed, when implanting the two pine needle-shaped nail portion to fracture, the two nail portions is gradually opened, each of the nail to support the fracture have been researched. This means that I will be to support the fracture in isosceles isosceles triangle. In order to have taken such a shape, reduction of the fracture it can hold, that the tip of the nail breaks through the articular surface 1 of the distal radius without any, also nail in a state in which the fracture has been well Seifuku a base it is possible to prevent shortening by lateral stops on the Kirschner wire 10 _1, 10 ₂ to the diaphyseal.
