[Stable interlocking intramedullary nailing of humeral fractures with the Seidel nail]

22 fractures of the humerus (15 traumatological, 7 pathological) were treated with the Seidel-Nail. The results after a follow-up between 4 and 20 months showed good mobility of the shoulder. As major complications two paresis of the radial nerve occurred. One disappeared spontaneously. The Seidel-Nail is a good implant for all kind of shaft fractures with an intact distal fragment of 5 cm and also for fractures of an intact humerus head.
