An expandable intra-osseous implant for a bone, e.g. vertebra, comprises a support structure defining a longitudinal axis. First and second sets of movable parts are mounted to the support structure. Each movable part comprises a load resisting surface for resisting a load external to the implant. In an unexpanded state of the implant they are circumferentially spaced around the longitudinal axis from each other, with the second set off-set in a longitudinal direction from the first set. The movable parts are movable relative to the support structure in a radial direction away from the longitudinal axis. A transmission for actuating movement of each movable part ofthe first and second sets along a predetermined path from the first position to the second position is present. In the expanded state the movable parts are supported against the external load to maintain the respective movable part in its position in the expanded state.
