Abstract: A vertebral prosthesis (10) comprising opposed ends (14,16) interconnected by a tubular side wall (12), which enclose a cavity therewithin. An inlet port (18) in fluid flow communication with the cavity permits injection of a hardenable fluid into the cavity. The tubular side wall has an expanding bellows configuration which allows for expansion of the vertebral prosthesis in an axial direction (23) such that the ends are displaced away from each other when the cavity is filled with the hardenable fluid, thereby axially expanding the vertebral prosthesis from a collapsed position to an expanded position in order to fill a space between adjacent vertebral bodies (11,13). The vertebral prosthesis (10) has an expansion ratio, defined by a total axial height of the vertebral prosthesis in the expanded position divided by a total axial height of the vertebral prosthesis in the collapsed position, that is greater that 200 percent.
