AbstractA 68 year old patient with persistent feeling of sickness and increasing pain in the left forearm was seen. A complex both bone fracture of the distal forearm shaft had been stabilized with Küntscher nails in radius and ulna 35 years ago. The loose ulna nail had been removed after ten weeks. Reosteosynthesis twelve months later with a Küntscher nail and cerclages had led to osteomyelitis and persistent bone defect, possibly caused by galvanic reaction between the different alloyies. A lymphocyte transformation test with nickel sulphate confirmed an allergic reaction and supported the indication to late implant removal. After exposure of the nail's end by a short approach a sufficient take over of power to the implant was reached by a coupling pole. Extraction was stopped after two centimetres by a blockage of the nail. Widening the entry of nail and drilling its whole notch by means of a Kirschner wire using the radiolucent ruler and by the repeated extraction and reinsertion led finally to the complete removal of the nail. Whereas local pain is disappeared three month after removal presenting bland local findings the general condition is improved slowly. Already Küntscher described the blockage of his nail after a short distance extraction. In addition to a number of not always successful means of extraction this method is described for the first time.
