title: [Intramedullary interlocking of humeral fractures and nonunions with Seidel nail].
abstract: The advantages and disadvantages of interlocking Seidel's nails determined by their construction and the way of insertion were presented on the basis of own experience and literature. The advantages are strength and shape of the nails which are conductive to fragments stability and make insertion into humerus medullar canal easier. The tools set for insertion and locking of distal part. It doesn't truly protect from torsion displacements. Locking takes place by draw for a few weeks by external immobilization. The Seidel's nail has also disadvantages associated with proximal insertion. Unavoidable injury of supraspinatus tendon insertion can be the reason of loss of shoulder function. The antegrade fixation can cause pushing distal fragment downward by tip of the nail. It is necessary to control it's insertion under image intensifier. Presented disadvantages of Seidel's nail fixation didn't result in any problems in humerus fractures or pseudoarthroses healing. In one case it was necessary to perform additional decortication and space of fracture fulfillment with bone grafts.
