    摘要: Die vorliegende Anmeldung betrifft eine Vorrichtung zur Stabilisierung von Röhrenknochenbrüchen umfassend ein als Wendelstab (10) ausgebildetes, in den Hohlraum eines Röhrenknochens einführbares Stabilisierungselement, welches an mindestens einem Ende eine Einrichtung zum Festlegen aufweist. Es ist vorgesehen, dass der Wendelstab neben einer sehr hohen Vertikalfederrate insbesondere eine gegenüber einem Marknagel auf das "physiologische" Maß abgesenkte Biegefederrate aufweist, so dass nach dem Einbringen in den Knochen minimale heilungsfördernde Bewegungen ausgelöst werden. Der Wendelstab hat weiterhin bevorzugt einen genormten einheitlich konfigurierten Kopf, der von dem variablen an den jeweiligen Knochen angepassten Außendurchmesser des Wendelstabs unabhängig ist. Da der Kopf einheitlich konfiguriert und genormt ist, kann unabhängig von der Größe (Durchmesser) des jeweils bei der Operation verwendeten Wendelstabs (10) beim Eindrehen ein einheitliches Werkzeug eingesetzt werden. Im Kopfbereich kann man auch angreifen, um die Schraubenfeder wieder heraus zu drehen.

    摘要: A device (404), for securing a first bone fragment (19) to a second bone fragment (21), comprising:
    an elongate pin (405), having a first retention structure (406);
    at least one distal anchor (34) carried by the elongate pin; and
    a proximal anchor (400) comprising a second retention structure (408), a tubular body (412), an annular flange (414), and a plurality of slots (416), the tubular body being axially slidably carried on the elongate pin, the annular flange defining an angular bone contacting surface (415), the plurality of slots defining a plurality of lever arms (418),
    wherein at least a portion of the second retention structure is moveable between a position located closer to a longitudinal axis of the elongate pin so as to engage at least a portion of the first retention portion and prevent proximal movement of the proximal anchor and another position which allows distal movement of the proximal anchor.

    摘要: The locking screw (1) comprises a screw head (2), a screw shank (3) having a diameter (d) and a central line (4) that is defined as a connecting line of the centers of gravity of the axially successive orthogonal cross-sectional areas of the locking screw (1). The locking screw also comprises an exit point (5) on the screw head (2) and an exit point (6) on the free end of the screw shank (3), however, the central line (4) is not a continuous straight line. The inventive locking screw enables the elimination of play between the cross-boring of the intramedullary nail and of the locking screw.

    摘要: Posterior fusion system, screw-rod-connector, whose screw the body that is screwed in the bones is characterized by clockwise threads, helical attached to an anti-clockwise rotating central spring consisting of a core and anti-clockwise wings. The screw functions as an implant, since it is incorporated in the surrounding spongiosa bone completely, with the two rotated at 180 degrees helical compartments that allow communication and contact in a 360 degrees direction. Its front section is hollow and slightly pointed. Its connection is accomplished with a joint and divisible rod with free movement before the nut's final tightening, separately for each vertebra, thanks to two receptions of the joint and the rod's spherical heads. This eases the placement and also the rod's application without any tension and after tightening the nut it immobilizes it in any position and allows all reduction handling, before the final tightening. The whole system assembled in this way and with a flexible screw, which withstands more fatigue than the solid one, is incorporated much faster because the screw acts as an implant and thus withstands more fatigue. Finally, it increases the construction's longevity, reducing loosening danger from the implantation site.
