Abstract: A height-variable vertebral body implant having a first, essentially U-shaped or C-shaped cage, and vertebral support surfaces formed on the first cage. The first cage is an inner cage, which is embraced and guided in a telescopic manner by a second, outer U-shaped or C-shaped cage. Further, legs of the inner and the outer cage are aligned such that a continuous lateral opening is obtained, and the inner and the outer cages are mutually fixed in a predetermined final position. The inner cage includes in an area of a part connecting the legs a longitudinally extending elongated hole having a unilateral toothing. In cooperation with an instrument including a complementary toothing, a relative movement and adjustment may be effected between the cages. In addition, a thread bore is formed in the outer cage in a position below the area of the elongated hole to fix a desired adjustment position.
