title: [The UFN-system (unreamed femoral nail)--avoidable intra- and postoperative complications].
abstract: We give an account of the first Austrian clinical results of a prospective study dealing with fractures of the femoral shaft treated with the UFN-system, the intraoperative handling especially considering the intra- and postoperative complications. The UFN-system combines the advantages of numerous proximal interlocking options for the treatment of nearly all femoral fracture patterns with that of the unreamed nailing (biological osteosynthesis, primary stability with individual after-treatment, high patient's comfort and early mobilisation). Within two years (VII/94-VII/96) sixty closed and four second degree open fractures were stabilized with the unreamed femoral nail. In twelve cases we used the spiral blade interlocking technique. Five times we changed from external fixator to the UFN. The fractures were classified according to the AO-classification. In 64 implanted UFN there occurred twelve intraoperative and four postoperative complications. In five cases reoperation was necessary. Failings in the operative technique, numerous different experienced surgeons and a deficient after_treatment led to our pitfalls.
