Abstract

An intervertebral implant (1) comprises a first part (10) having a first end, a second end, a first contact surface (12) provided between the first and second ends, and a first guide surface extending out from the first contact surface; and a second part (20) having a third end, a fourth end, a second contact surface (22) provided between the third and fourth ends, and a second guide surface recessed into the second contact surface. An intervertebral implant comprises a first part having a first end, a second end, a first contact surface provided between the first and second ends, and a first guide surface extending out from the first contact surface; and a second part having a third end, a fourth end, a second contact surface provided between the third and fourth ends, and a second guide surface recessed into the second contact surface, the first and second guide surfaces comprising cooperating structures, so that the first contact surface of the first part can slide relative to the second contact surface of the second part, with a translation motion guided by the cooperating structures of the first and second guide surfaces. An independent claim is also included for a method of stabilizing two spaced vertebrae, comprising providing an intervertebral implant; adjusting the height of the implant by connecting the second end of the first part with the third end of the second part, and moving the first contact surface relative to the second contact surface, to bring the first end of the first part closer to the fourth end of the second part using the cooperating guide surfaces; and inserting the adjusted height implant between the vertebrae in need of stabilization.

Description

Die vorliegende Erfindung bezieht sich auf ein höheneinstellbares Zwischenwirbelimplantat.The The present invention relates to a height adjustable intervertebral implant.

Zwischenwirbelimplantate werden insbesondere nach der Entfernung einer Bandscheibe eingesetzt, um den Zwischenraum zwischen den Wirbelkörpern zu stabilisieren.Fusion Implants are used in particular after the removal of an intervertebral disc, to stabilize the space between the vertebral bodies.

Ein solches Zwischenwirbelimplantat ist in der EP 0 977 529 B1 beschrieben. Es ist im Wesentlichen quaderförmig ausgebildet und weist zwei Seitenwände, eine Vorderwand und eine Rückwand auf. Die Boden- und Deckfläche sind offen ausgebildet. In den von den vier Wänden umschlossenen Hohlraum enthält das Zwischenwirbelimplantat wenigstens ein Element mit einer zur Deckfläche bzw. zur Bodenfläche gerichteten Oberfläche und ein in der Vorderwand und in der Rückwand gelagertes Einstellelement, so dass das Element zwischen einer ersten Stellung, in der seine Oberfläche nicht über die Deckfläche bzw. Bodenfläche hervorsteht, und einer zweiten Stellung, in der seine Oberfläche über die Deckfläche bzw. Bodenfläche hervorsteht, hin und her bewegt werden kann. Dadurch kann die Endhöhe des Zwischenwirbelimplantats eingestellt werden.Such an intervertebral implant is in the EP 0 977 529 B1 described. It is formed substantially cuboid and has two side walls, a front wall and a rear wall. The bottom and top surfaces are open.
