  • Telescopic vertebral prosthesis
    Patent number: 6176881
    Abstract: The invention relates to a device for replacing vertebral bones. The device includes an interior hollow body and an exterior hollow body. These hollow bodies can slide into each other coaxially along a central axis and can be moved in relation to one another in the direction of the central axis. The interior hollow body is provided with a catch mechanism on its outer surface. The exterior hollow body includes a hole or bore extending along the central axis. The exterior hollow body also includes at least one elastic element that projects into the bore at its top end. This reduces the diameter of the bore so that the elastic element latches onto the catch mechanism of the interior hollow body, thereby fixing the length of the device in such a way that it is resistant to compression.
