[2 Kirschner wires as simplified external fixation devices in finger joint arthrosis].

A new technique for arthrodesis of the PIP joint is described; after resection of the joint two percutaneous Kirschner wires of diameter 1.2-1.3 mm are placed transversely through the two phalanges. The wires are twisted together on each side of the finger to produce a compression effect on the bone surface. Additional external immobilisation is used for five days only, but the wires are left in place for six weeks. The method has been used without complication in ten patients. The average length of time off work was seven and a half weeks. In the author's view the advantages of this method lie in its technical simplicity and in the free movement of other finger joints.
