Abstract
Description
Die Erfindung betrifft eine Knochenplatte zum Einsatz an den unteren Extremitäten zur Korrektur der als Hallux Valgus bekannten Knochendeformation. Die Erfindung betrifft auch die Verwendung der Knochenplatte in besonderer Weise.The The invention relates to a bone plate for use on the lower Extremities to correct for what is known as hallux valgus Bone deformation. The invention also relates to the use of Bone plate in a special way.
Aus
der
Nachteilig dabei ist, dass in manchen Fällen die Platte durch einen zweiten operativen Eingriff entfernt werden muss. Weiter ist diese Positionierung der Platte nicht optimal hinsichtlich der auftretenden Kräfte. Der Osteotomiespalt wird mehr auf Zug als auf Druckkraft belastet. Dies kann zu einer verlängerten Frakturheilung führen gegenüber der Erfindung.adversely it is that in some cases the plate by a second surgery must be removed. Next is this Positioning of the plate is not optimal with regard to the forces that occur. The osteotomy gap is loaded more by tension than by compressive force. This can lead to a prolonged fracture healing towards the invention.
Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine verbesserte Knochenplatte zu schaffen, die eine besonders sichere Fixierung des Knochens ermöglicht und dafür optimiert ist, bei der operativen Korrektur der Hallux Valgus Deformation plantar von unten an den Knochen angelegt werden zu können. In dieser Position werden die den Vorfuss belastenden Kräfte biomechanisch in optimaler Weise übertragen.In contrast, The invention is based on the object, an improved bone plate to create, which allows a particularly secure fixation of the bone and is optimized for the surgical correction of Hallux valgus deformity plantar created from below on the bone to be able to. In this position, the forefoot burdening Transmit forces biomechanically in an optimal way.
Zur Lösung dieser Aufgabe ist erfindungsgemäß eine Knochenplatte vorgesehen, die die Merkmale des Patentanspruchs 1 aufweist.to Solution to this problem is according to the invention a Provided bone plate having the features of claim 1 having.
Das Besondere bei der aufgefundenen Lösung ist, dass
- – die Knochenplatte einen im wesentlichen flachen langen Schenkel und einen an dessen einem Ende im wesentlichen L-förmig oder T-förmig anschließenden, dicker als der lange Schenkel ausgebildeten kurzen Schenkel aufweist, wobei die Längsachse des kurzen Schenkels in einer zur Plattenebene des langen Schenkels parallelen Ebene liegt, dass
- – die Plattenebene des langen Schenkels von wenigstens einem Durchgangsloch senkrecht durchdrungen ist, und dass
- – der kurze Schenkel von wenigstens einem Durchgangsloch in der Weise schräg durchdrungen ist, dass die Achse des Durchgangslochs in einer Ebene liegt, die zu der Schar der Ebenen, die senkrecht zur Längsachse des langen Schenkels und zu dessen Plattenebene orientiert sind, einen spitzen Winkel bildet,
- – wobei die Gewindeenden der durch die Durchgangslöcher geführten Knochenschrauben aufeinander zulaufen.
- - The bone plate has a substantially flat long leg and at one end substantially L-shaped or T-shaped subsequent, thicker than the long leg formed short leg, wherein the longitudinal axis of the short leg in parallel to the plate plane of the long leg Level is that
- - The plate plane of the long leg is penetrated perpendicularly by at least one through hole, and that
- - The short leg of at least one through hole is obliquely penetrated in such a way that the axis of the through hole lies in a plane which forms an acute angle to the family of planes which are oriented perpendicular to the longitudinal axis of the long leg and to its plate plane .
- - The threaded ends of the guided through the through holes bone screws converge.
Weitere Ausgestaltungen der erfindungsgemäßen Knochenplatte sind in den Patentansprüchen 2 bis 9 angegeben.Further Embodiments of the bone plate according to the invention are given in the claims 2 to 9.
Mit Patentanspruch 10 wird ein selbständiger Patentschutz für die Verwendung der erfindungsgemäßen Knochenplatte beansprucht.With Claim 10 is an independent patent protection for the use of the bone plate according to the invention claimed.
Patentanspruch 11 betrifft die vorteilhafte Ausbildung der Knochenplatte bei der erfindungsgemäßen Verwendung.claim 11 relates to the advantageous embodiment of the bone plate in the use according to the invention.
Nachfolgend wird die Erfindung im Rahmen eines Ausführungsbeispiels näher erläutert.following the invention is within the scope of an embodiment explained in more detail.
Die
einzige Figur zeigt die erfindungsgemäße Knochenplatte
in perspektivischer Darstellung. Sie weist einen mit
Beide
Schenkel sind von je zwei Durchgangslöchern durchdrungen,
durch die insgesamt vier Knochenschrauben
Wie
in der Figur gezeigt durchdringen die Schrauben
Bei
dem gezeigten Ausbildungsbeispiel liegen die Achsen der Schrauben
Wie
in der Figur gezeigt steht der kurze Schenkel
Der
kurze Schenkel
Die
Knochenplatte besteht, ebenso wie die Schrauben
Die Knochenplatte nach dem Ausführungsbeispiel ist optimiert zum Anlegen an den Knochen von unten (plantar). Zur Anpassung an den Knochenverlauf ist die Anlagefläche gekrümmt ausgebildet.The Bone plate according to the embodiment is optimized for attachment to the bone from below (plantar). To adapt to the bony course, the contact surface is curved educated.
Es versteht sich von selbst, dass die Knochenplatte auch spiegelsymmetrisch zu der in der Figur gezeigten Raumform ausgebildet sein kann, so dass sie entweder am rechten oder am linken Fuß verwendet werden kann.It It goes without saying that the bone plate is also mirror-symmetrical may be formed to the space shape shown in the figure, so that they are used on either the right or the left foot can.
Die besonderen Vorteile dieser Knochenplatte liegen darin, dass die plantare Anlage der Platte aus biomechanischer Sicht eine optimale Stabilität bei der Fussbelastung nach dem Zuggurtungs-Osteosynthese-Konzept aufweist. Die Kräfte die durch Belastung an den Mittelfussknochen ausgeübt werden, werden in Kompressionskräfte an der Osteotomie umgewandelt. Dadurch erhöht sich die Stabilität und die Knochenheilung wird gefördert.The particular advantages of this bone plate are that the plantare plant the plate from biomechanical point of view an optimal Stability in foot load according to the Zuggurtungs Osteosynthesis concept having. The forces caused by strain on the metatarsal bones are exercised in compression forces transformed at the osteotomy. This increases the Stability and bone healing is promoted.
Die L- oder die T-Form der Platte ermöglicht eine optimale Konformität zum Knochen nach Durchführung der Korrektur.The L or the T-shape of the plate allows optimal Conformity to the bone after performing the Correction.
Die vorgegebene winkelstabile Schraubenrichtung an dem kurzen Schenkel der L-förmigen Platte ermöglicht eine optimale Fixierung in dem körpernahen (proximalen) Segment des durchtrennten Mittelfussknochens und verhindert die versehentliche Positionierung der Schrauben in das benachbarte Gelenk. Die Festlegung der Schraubenrichtung, basiert auf eingehenden anatomischen Studien.The given angular stable screw direction on the short leg The L-shaped plate allows optimal Fixation in the proximal segment of the severed metatarsal bone and prevents accidental positioning of the screws in the adjacent joint. The definition of the screw direction, based on detailed anatomical studies.
Dieses Verfahren beabsichtigt eine anatomische Wiederherstellung des ersten Strahls bei der Korrektur der Hallux valgus Fehlstellung, ohne Längenverlust des ersten Mittelfussknochens. Unter Massgabe der Wundheilung ist eine rasche Belastung möglich.This Procedure intends an anatomical restoration of the first Ray in the correction of hallux valgus malposition, without loss of length of the first metatarsal bone. Under the condition of wound healing is a quick load possible.
