Height-adjustable intervertebrae implant
First Claim
1. An intervertebral implant comprising:
- 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 guide surface and the second guide surface 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.

Abstract
An intervertebral implant for insertion between two vertebrae is disclosed. A first part has a first contact surface extending between its two ends a first guide surface extending out from the first contact surface. A second part has a second contact surface extending between its ends, and a second guide surface recessed into the second contact surface. The first guide surface and the second guide surface cooperate 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. The height of the intervertebral implant can be altered by shifting the first part and the second part relative to each other by moving the contact surfaces relative to each other by using the cooperating guide surfaces.

18. A method of stabilizing two spaced vertebrae, the method comprising:
-
providing an intervertebral implant comprising;
a first part having a first end, a second end, a first contact surface extending 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 extending between the third and fourth ends, and a second guide surface recessed into the second contact surface;
the first guide surface and the second guide surface 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;
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. - View Dependent Claims (19)
