Schiene für chirugiscne Zwecke zur· Ve bindung von gebrochenen KnochenteilenSplint for surgical purposes binding of broken bone parts
Die Erfindung betrifft eine Schiene für chirugische Zwecke zur Verbindung von gebrochenen Knochenteilen, die über in diese eingreifenden Schrauben mit der Schiene verbunden sind.The invention relates to a splint for surgical purposes for connecting broken bone parts, which are connected to the rail via screws engaging in this.
Es ist bereits eine Schiene bekannt, die mittels Schrauben an die Knochenbruchstücke b.ef estigt werden. Diese starre Verbindung zwischen Schiene und Knochen macht es unmöglich, Längs- und Querverschiebungen, die bei Belastung des Knochens durch Bewegungs- und Wachstums ein flüßen entstehen, auszugleichen. Die Folge davon ist ein Ausbrechen der Gewindegänge im Knochen und caniit ein ungewolltes Lösen der Schraubverbindung.A splint is already known which is fastened to the bone fragments b.ef by means of screws. This rigid connection between the splint and the bone makes it impossible for longitudinal and transverse movements when the bone is stressed by movement and growth a river will arise, balance. The consequence of this is that the threads in the bone break out and caniit an unintentional loosening of the screw connection.
Um diesen Nachteilen abzuhelfen, wird erfindur.gsgeiTietS vorgeschlagen, den Schraubenkopf und/oder Schraubenscnaft mit einer elastisch nachgiebigen Kunststoffeinlage zu umgeben.In order to remedy these disadvantages, inventions suggested the screw head and / or screw bolt to be surrounded with a resilient plastic insert.

Scp.it it is possible that the Screw 2,3, the displacement of the 3ohrur.g may start as the bone grows after the splint is in place.
In zweckmäßiger Weise kann nach einem weiteren Merkmal der Erfindung die elastische Kunststoffeinlage über dera Schraubenkopf nach innen umg-efaßt sein. Damit ist noch zusätzlich eine Sicherung gegen Herausfallen und Lösen der Schraube aus dem Bohrloch geschaffen.Conveniently, the resilient plastic insert may be according to a further feature of the invention over dera screw head inside umg-efaßt. This also provides a safeguard against falling out and loosening of the screw from the borehole.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt.Two exemplary embodiments of the invention are shown in the drawing.
