Beschreibung der FederschraubeDescription of the spring screw
In der Unfallchirurgie gibt es Situationen, in denen zwei Knochen gelenknah verbunden werden müssen. Die derzeitig übliche starre Schraubenverbindung (sog. Stellschraube) erfordert eine weitgehende Ruhigstellung des Gelenkes, da es durch Gelenkbewegung zur Schraubenlockerung bis hin zum Knochen- oder Schraubenbruch kommen kann. Diese Komplikation gefährden das Operationsergebnis. Um der Schraubenverbindung eineIn trauma surgery, there are situations in which two bones must be connected close to a joint. The currently common rigid screw connection (so-called set screw) requires the joint to be immobilized to a large extent, as joint movement can lead to screw loosening and even bone or screw breakage. These complications endanger the surgical outcome. In order to give the screw connection a
gewisse Elastizität zu verleihen, schlug Bosworth1 die Unterlegung des Schraubenkopfes mit einer Federscheibe vor. Die Federscheibe hat sich jedoch in der Praxis nicht bewährt, da die Flexibilität zu gering ist.To give the screw a certain degree of elasticity, Bosworth 1 suggested placing a spring washer under the screw head. However, the spring washer has not proven to be effective in practice because it is not very flexible.
Problemlösung:Troubleshooting:
Mit Hilfe einer Federschraube ist das Gelenk zwar stabilisiert aber nicht starr verbunden. Ein kleines Bewegungsspiel ist möglich, so daß die an Knochen und Schraube auftretenden Kräfte durch die Verformbarkeit der Schraube gemindert werden. 25 With the help of a spring screw, the joint is stabilized but not rigidly connected. A small amount of movement is possible, so that the forces acting on the bone and screw are reduced by the deformability of the screw. 25
Der Schaft der Federschraube ist in drei Abschnitte gegliedert:The shaft of the spring screw is divided into three sections:
A. Massivabschnitt: im Anschluß an den Kopf, Rundling mit zentraler Bohrung.A. Solid section: following the head, round section with central hole.
B. Federabschnitt: Spiralfeder.B. Spring section: spiral spring.
C. Gewindeabschnitt: Die zentrale Bohrung ist hier als Vierkantimbus gearbeitet, siehe Abb. 1. C. Threaded section: The central hole is machined as a square Allen key, see Fig. 1.
Um die eingearbeitete Spiralfeder beim Ein- und Ausschrauben von Rotationskräften zu entlasten, erfolgt die Kraftübertragung im Gewindeabschnitt der Schraube. In diesem Abschnitt ist die zentrale Bohrung als Imbus gearbeitet, siehe Abb. 1. In order to relieve the integrated spiral spring of rotational forces when screwing in and out, the force is transmitted in the threaded section of the screw. In this section, the central hole is machined as an Allen key, see Fig. 1.
Die Anwendung der Federschraube ist bei verschiedenen Verletzungen möglich, z.B.: - als Stellschraube bei der Schultereckverletzung (Tossy III), siehe Abb. 2, The spring screw can be used for various injuries, e.g.: - as an adjusting screw for acromioclavicular injury (Tossy III), see Fig. 2,
- als Stellschraube zur Stabilisierung der Bandverbindung zwischen Wadenbein und Schienbein bei Sprunggelenksfrakturen (Weber C), siehe Abb. 3, - as an adjusting screw to stabilize the ligament connection between the fibula and tibia in ankle fractures (Weber C), see Fig. 3,
- als Stellschraube bei Sprengungen der Bandverbindung im Handgelenk zwischen Elle und Speiche, siehe Abb. 4. - as an adjusting screw in case of tears in the ligament connection in the wrist between the ulna and radius, see Fig. 4.
