Abstract

The titanium osteosynthesis plate has two slanting and axial arms in the shape of a letter Y. The arms can be set on all planes and can be adapted to the anatomical characteristics of the bone broken or needing correction. The plate is mainly placed against the stretch side of the radius. The two arms differ in length with the longer arm fixable to the radius-side of the radius-extension.

Description

Osteosyntheseplatten zur Implantation, anatomischen Reposition und inneren Schienung von Knochenfragmenten nach Frakturen des distalen Radius sind weithin bekannt. Sie sind - bereits nach Vorschlag der AO - zumeist T-förmig, wobei der lange Schenkel des T an den Knochenschaft, der kurze, winklig zum anderen befindliche Schenkel weitgehend parallel zur distalen Radiusgelenkfläche, d. h. quer zur Knochenlängsachse fixiert wird.Osteosynthesis plates for implantation, anatomical reduction and internal splinting of Bone fragments after fractures of the distal radius are well known. They are - already according to the proposal of the AO - mostly T-shaped, with the long leg of the T on the Bone shaft, the short leg at an angle to the other largely parallel to the distal radius articular surface, d. H. is fixed transversely to the longitudinal axis of the bone.

An der Beugeseite des distalen Radius lässt sich dies auch gut bewerkstelligen, hingegen erschwert der trapezförmige Querschnitt des distalen Radius (Abb. 4) mit der Trapezspitze - anatomisch tuberculum LISTERI genannt - an der Streckseite die Anlage einer solchen Platte auf der Streckseite. So muss der Knochen durch Abmeißeln oder -sägen von Knochenvorsprüngen an die Platte angepasst werden. Diese vorgenommene Veränderung stört jedoch empfindlich das ohnehin sehr sensible Gefüge der Weichteilstrukturen an der Streckseite des distalen Radius (Nicoloff, M., H. Dittmer: Die Y-Platte zur dorsalen Osteosynthese des distalen Radius. Akt. Traumatol. 29 (1999) 61-65).This can also be done well on the flexor side of the distal radius, but the trapezoidal cross section of the distal radius ( Fig. 4) with the trapezoid tip - anatomically called tubercle LISTERI - on the extensor side makes it difficult to place such a plate on the extensor side. For example, the bone has to be adapted to the plate by chiseling or sawing off bone projections. However, this change disturbs the already very sensitive structure of the soft tissue structures on the stretch side of the distal radius (Nicoloff, M., H. Dittmer: The Y-plate for the dorsal osteosynthesis of the distal radius. Act. Traumatol. 29 (1999) 61- 65).

Der Erfindung liegt die Aufgabe zugrunde, die Form der bekannten Osteosyntheseplatten für die Implantation am distalen Radius so zu modifizieren, dass ein anatomiegerechtes Anlegen und Fixieren der Platte an der Streckseite des Radius ohne die Notwendigkeit von Veränderungen am Knochen und mit der Möglichkeit weitgehender Weichteilschonung erreicht wird.The invention has for its object the shape of the known osteosynthesis plates for modify the implantation on the distal radius so that it fits anatomically and fixing the plate to the extended side of the radius without the need for Changes in the bone and with the possibility of extensive soft tissue protection is achieved.

Die Aufgabe ist gemäß der Erfindung dadurch gelöst, dass man die beiden Schenkel der Platte den anatomischen Gegebenheiten durch Schränkung in allen Ebenen anpassen kann (Abb. 6 -8). Die Anpassung an die Trapezform des Querschnitts der distalen Speiche (Abb. 4) ermöglicht einen konvergenten Verlauf der Achsen der einzubringenden Knochenschrauben. Damit lässt sich im Falle von Frakturen, welche in das Gelenk hineinreichen, eine gewünschte interfragmentäre Kompression erreichen. According to the invention, the object is achieved in that the two legs of the plate can be adapted to the anatomical conditions by setting in all planes ( Fig. 6-8). The adaptation to the trapezoidal shape of the cross-section of the distal spoke ( Fig. 4) enables the axes of the bone screws to be converged. In the case of fractures that reach into the joint, a desired interfragmentary compression can be achieved.

Das längsovale Schraubenloch ermöglicht bei zusätzlicher Fixierung zweier distaler Schrauben das Verschieben der Osteosyntheseplatte in der Längsachse des Radius zur Korrektur der Knochenlänge sowie der Achse und der Gelenkwinkel ohne die Gefahr einer Dislokation der distalen Knochenfragmente (Abb. 3).The longitudinal oval screw hole allows additional fixation of two distal screws to move the osteosynthesis plate in the longitudinal axis of the radius to correct the bone length as well as the axis and the joint angle without the risk of dislocation of the distal bone fragments ( Fig. 3).

Die Y-Form der Platte ermöglicht das Einbringen von Knochenspänen im Falle einer Defekthöhle im Frakturbereich bei liegender Platte, so dass das Repositionsergebnis nicht gefährdet wird (Abb. 4).The Y-shape of the plate enables bone chips to be inserted in the case of a defect cavity in the fracture area with the plate lying flat, so that the reduction result is not endangered ( Fig. 4).

Die zwei enger zueinander liegenden Schraubenlöcher am distalen Ende des kürzeren Schenkels ermöglichen eine exakte Fixierung von Knochenfragmenten, die ellenseitig streckseitig herausgebrochen sind (Abb. 5).The two screw holes located closer to each other at the distal end of the shorter leg enable precise fixation of bone fragments that have broken out on the stretch side ( Fig. 5).

Die Verjüngungen der Osteosyntheseplatte zwischen den Schraubenlochumrandungen führen zu einem quantitativ verringertem Kontakt zwischen Platte und Knochenhaut, was für die arterio-venöse Zirkulation von Vorteil ist.Guide the taper of the osteosynthesis plate between the screw hole borders to a quantitatively reduced contact between the plate and the periosteum, which for the arterio-venous circulation is beneficial.

Die geringe Dicke der Platte ist günstig zur Schonung der Weichteile; sie führt aufgrund der Existenz von zwei vorhandenen Schenkeln der Platte nicht zu einem Stabilitätsverlust. Aufgrund der geringen Weichteilirritation durch die Platte sowie aufgrund des gewebeverträglichen Materials (Titan) entfällt die Notwendigkeit einer Implantatentfernung.The low thickness of the plate is favorable for protecting the soft parts; because of the Existence of two existing legs of the plate does not result in a loss of stability. Due to the low soft tissue irritation due to the plate and due to the tissue compatible material (titanium) eliminates the need for implant removal.
