Abstract
Description
Die Osteosynthese- bzw. Rekonstruktionsplatten nach Anspruch 1 und mit den von der AO vorgeschlagenen sphärischen Gleitlochprinzip (s. Skizze 1a-d), dienen der funktionsstabilen anatomischen Fixierung von Knochenfragmenten nach Frakturen, z. B. in der Ex tremitäten und craniofacialen Chirurgie, bei der chirurgischen Behandlung von craniofacialen Anomalien, Malokklusionen und der Rekonstruktion nach tumorchirurgischen Eingriffen.The osteosynthesis or reconstruction plates according to claim 1 and with the spherical sliding hole principle proposed by the AO (see sketch 1a-d), serve the functionally stable anatomical Fixation of bone fragments after fractures, e.g. B. in the Ex tremors and craniofacial surgery, in surgical Treatment of craniofacial abnormalities, malocclusions and the Reconstruction after tumor surgery.
Die je nach Indikation zu verwendenden Platten (z. B. bei der Extremitätenchirurgie Abb. 1 oder cranialen Chirurgie Abb. 2) weisen auf der Unterseite, die dem Knochen anliegt, eine sphä rische Noppung auf. Abb. 1 und Skizze 1b-d.Depending on the indication, the plates to be used (e.g. in extremity surgery Fig. 1 or cranial surgery Fig. 2) have a spherical nub on the underside, which lies against the bone. Fig. 1 and sketch 1b-d.
Durch diese noppenförmige Gestaltung der Plattenunterseite paßt sich die Platte dem Makrorelief des Knochens genauer an. (s. CT- Bilder des Unterkiefers in Abb. 3d, Abb. 5b.)Due to this knob-shaped design of the underside of the plate, the plate adapts more precisely to the macro relief of the bone. (see CT images of the lower jaw in Fig. 3d, Fig. 5b.)
Es entsteht somit ein homogeneres Gefüge zwischen Knochen- und Osteosyntheseplatte.This creates a more homogeneous structure between bone and Osteosynthesis plate.
Umständliches und zeitraubendes Anpassen herkömmlicher Osteosynthese platten mit planer knochenseitiger Unterseite lassen sich auf ein Minimum reduzieren und die Narkosedauer läßt sich dadurch verkürzen. Die Gefahr der Plattenlockerung, die mit lokaler Infektion, Ver änderung im Bereich der Weichteile und der Operationsnarbe und im ungünstigsten Fall mit Fistelbildung und Auftreten von Dehiszenzen einhergehen, läßt sich durch die noppenförmige Bauweise günstig beein flussen. Die Noppen, die im günstigen Fall in die Tiefe des Makro reliefs des Knochens eingreifen, führen zur erhöhten Retention zwi schen Platte und Bruchenden, dadurch zur verbesserten Stabilisation der Bruchenden (s. Abb. 1-6). Das Risiko von Pseudoarthrosen und Wundheilungsstörungen können damit günstig beeinflußt werden. Cumbersome and time-consuming adaptation of conventional osteosynthesis plates with a flat underside on the bone side can be reduced to a minimum and the duration of anesthesia can be shortened. The risk of loosening of the plate, which is associated with local infection, changes in the area of the soft tissues and the surgical scar and, in the worst case, with fistula formation and the occurrence of dehiscences, can be favorably influenced by the knob-shaped construction. The knobs, which in the favorable case reach into the depth of the macro relief of the bone, lead to increased retention between the plate and the fracture ends, thereby improving the stabilization of the fracture ends (see Fig. 1-6). The risk of pseudoarthrosis and wound healing disorders can thus be influenced favorably.
Abb. 3 und 4 zeigen an hand computertomographisch erstellter Schichtbilder des Ramus ascendens des menschlichen Unterkiefers die individuell unterschied lichen Strukturen des Knochens, das Makrorelief (D), die Dichte des Knochens im Dichteprofil (F) entlang einer Strecke (E). In der Fotomontage ist mit A die in Anspruch 1 aufgeführte Platte gekennzeichnet, mit C Schraube mit halbkugelförmigen Schraubenkopf und mit G das Gleitloch. Figs. 3 and 4 show the individually different structures of the bone, the macrorelief (D) , the density of the bone in the density profile (F) along a path (E) using computed tomography slice images of the ascending ramus of the human lower jaw. In the photomontage, the plate listed in claim 1 is identified by A , by C a screw with a hemispherical screw head and by G the gliding hole.

Prinzip der dynamischen Compression Platte mit modifiziert gestalteter Platten unterseite.Principle of the dynamic compression plate with modified plates bottom.
- a) Sphärisches Gleitprinzip; Schraube mit halbkugelförmigem Schraubenkopf gleitet beim Eindrehen am bruchspaltfernen Ende des Schraubenloches mit dem Knochenfragment zum Bruchspalt hin.a) spherical sliding principle; Screw with a hemispherical screw head slides when screwing in at the end of the screw hole away from the fracture gap the bone fragment towards the fracture gap.
- b) Eindrehen der Schraube am bruchspaltfernen Ende des Schraubenloches.b) Screw in the screw at the end of the screw hole far from the fracture gap.
- c) Eindrehen der rechten Schraube; Schraube gleitet mit Knochenfragment zum Bruchspalt hin.c) screwing in the right screw; Screw slides to the bone fragment Fracture gap.
- d) Festziehen der linken Schraube; hierdurch kommt es zur Adaption, Kompression und durch die sphärische Noppung der Plattenunterseite zur Retention und Friktion zwischen Platte und Bruchenden.d) tighten the left screw; this leads to adaptation, compression and due to the spherical knot on the underside of the plate for retention and Friction between plate and break ends.
