    Notes: Abstract Topological structural analysis is a terminology proposed for studying the behaviour of structures when the constitutive law is reduced to a least formulation. In addition to the equilibrium and deformation compatibility equations we only require that the extensional and contractile strains correspond, respectivley, to tensile and compressive stresses, without further specifying the nature of the constitutive law. The only analysis parameter in these equations is the equilibrium matrix which incorporates pure topological information such as node positions and bar connectivities. It is shown that in a topological context the internal forces, which can be realized by a structure, are bounded by a convex combination of the internal forces of its embedded statically determinate substructures. It is also shown that this “structural” equilibrium space is nonconvex. Consequently, the internal forces are bounded, component by component, by the internal forces in the statically determinate solutions. Having established that the structural equilibrium space is a small subset of the equilibrium space it is shown that pure equilibrium solutions, such as are obtained in plastic analysis and design, are not always feasible. It is conjectured that topological design of structures may benefit from using topological analysis rather than a pure equilibrium analysis.

    Description / Table of Contents: The major problems in the treatment of open fractures with high blood loss are hypothermia acidosis and coagulopathy. By improving the standards of polytrauma management and using massive transfusion systems, which should help to avoid those complications, the indication for primary limb salvage under hypovolemic shock conditions is greatly increased. The following case of an grade 3 open fracture of the femur with severe soft-tissue damage, including vascular lesions, with consecutive massive transfusion, should demonstrate that the cardiac-respiratory system can still be stabilized, even if a surgical solution seems impossible.
    Notes: Die Hauptprobleme bei der Versorgung offener Frakturen mit hohem Blutverlust sind Hypothermie, Azidose und Verbrauchskoagulopathie. Die Indikation zum Extremitätenerhalt trotz schwerer Weichteilschädigung wird aufgrund von verbesserter Primärversorgung und dem Einsatz von Massentransfusionssystemen, welche die genannten Komplikationen vermeiden helfen ständig erweitert. Ein Grenzfall der chirurgischen Versorgbarkeit bei Grad III offener Oberschenkelfraktur mit Läsion der Vasa femoralis unter Massentransfusionsbedingungen soll hier dargestellt und diskutiert werden. Diese Kasuistik soll zeigen, daß die Vitalfunktionen auch zu einem Zeitpunkt noch stabilisierbar sind, zudem die chirurgische Versorgung kaum noch möglich erscheint.
