Abstract

The invention 1. facilitates the surgical manipulation of osteosynthesis and reconstruction plates in the surgical treatment of fractures, in orthodontic operations and in the surgical treatment of craniofacial anomalies, 2. leads to a better retention and friction between plate and fracture ends and thus greater stability of the fracture, 3. reduces the risk of loosening of the plates and thus the danger of delayed wound healing. This is essentially achieved by the underside of a plate which faces the bone being provided with spherical knobs so that the best possible adaptation between the plate and the macrorelief of the bone is achieved. This makes it possible to reduce intricate and time-consuming adaption of the plate to the surface of the bone to a minimum.

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. The osteosynthesis plates according to claim 1 or reconstruction and with the proposed by the AO spherical Gleitlochprinzip (s. Sketch 1a-d), the functionally stable anatomical fixation of bone fragments after fractures, for serving. B. in der Ex tremitäten und craniofacialen Chirurgie, bei der chirurgischen Behandlung von craniofacialen Anomalien, Malokklusionen und der Rekonstruktion nach tumorchirurgischen Eingriffen. B. tremitäten in the Ex and craniofacial surgery, the surgical treatment of craniofacial anomalies, malocclusions and 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. To be used according to the indication plates (z. B. at the extremities surgery Fig. 1 or cranial surgery Fig. 2) have on the underside, which abuts the bone to a sphe generic embossment. Abb. 1 und Skizze 1b-d. Fig. 1 and diagram 1b-d.

Durch diese noppenförmige Gestaltung der Plattenunterseite paßt sich die Platte dem Makrorelief des Knochens genauer an. By means of this knob-shaped design of the plate bottom side of the plate fits the macro relief of the bone to more accurately. (s. CT- Bilder des Unterkiefers in Abb. 3d, Abb. 5b.) (s. CT images of the mandible in Fig. 3d, Fig. 5b).

Es entsteht somit ein homogeneres Gefüge zwischen Knochen- und Osteosyntheseplatte. It thus creates a homogeneous structure between bone and osteosynthesis.

Umständliches und zeitraubendes Anpassen herkömmlicher Osteosynthese platten mit planer knochenseitiger Unterseite lassen sich auf ein Minimum reduzieren und die Narkosedauer läßt sich dadurch verkürzen. Cumbersome and time-consuming adapting conventional osteosynthesis plates with a flat bottom, bone-side can be reduced to a minimum and the duration of anesthesia can be shortened thereby. 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. The danger of the plate loosening associated with local infection Ver change in the area of ​​soft tissue and the surgical scar and in the worst case with fistula formation and occurrence of dehiscence, can be favorably impressed by the influence knob-shaped design. 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). The studs which engage in the most favorable case in the depth of the macro-reliefs of the bone (Fig. 1-6 s.) Lead to increased retention Zvi rule plate and broken ends, thereby contributing to improved stabilization of the broken ends. Das Risiko von Pseudoarthrosen und Wundheilungsstörungen können damit günstig beeinflußt werden. The risk of nonunions and wound healing disorders can thus be influenced.

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) . Fig. 3 and 4 indicate hand computed tomography created layer images of the ascending ramus of the human lower jaw individually different union structures of the bone, the macro relief (D), the density of the bone (F) in the density profile along a path (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. In the photo mounting the plate referred to in claim 1 is characterized with A, with C screw having semi-spherical screw head and with G the slide hole.

  • a) Sphärisches Gleitprinzip; a) Spherical Gleitprinzip; Schraube mit halbkugelförmigem Schraubenkopf gleitet beim Eindrehen am bruchspaltfernen Ende des Schraubenloches mit dem Knochenfragment zum Bruchspalt hin. Screw with a hemispherical head screw slides when screwing on the fracture distal end of the screw hole with the bone fragment towards the fracture gap.
  • b) Eindrehen der Schraube am bruchspaltfernen Ende des Schraubenloches. b) screwing the screw on the fracture distal end of the screw hole.
  • c) Eindrehen der rechten Schraube; c) screwing in the right screw; Schraube gleitet mit Knochenfragment zum Bruchspalt hin. Screw slides with bone fragment towards the fracture gap.
  • d) Festziehen der linken Schraube; d) tightening the left screw; hierdurch kommt es zur Adaption, Kompression und durch die sphärische Noppung der Plattenunterseite zur Retention und Friktion zwischen Platte und Bruchenden. This results in the adaptation, compression, and by the spherical embossment of the plate underside for retention and friction between the plate and broken ends.
