Abstract: An expandable cage which is placed between the vertebrae, is moveable when preferred, closes the opening between the vertebrae upon being moved, and hence can be integrated in any intervertebral opening. The expandable cage has at least one body with at least one space and at least one rib; at least one moveable part which is located inside the body and has at least one bearing area, at least one base, and at least one nail, the moveable part being moved unilaterally by the balloon; at least one balloon which applies the force required to be applied on the base of the moveable part for ensuring unilateral movement of the moveable part; at least one hole through which the balloon can pass; and at least one compression element which supplies the required fluid to the balloon.

Abstract: The invention relates to an expandable cage (1) which is placed between two vertebrae and expandable at a preferred ratio towards the vertebrae, and hence mountable in any intervertebral space.

Abstract: This invention is related to a cable system (1) having a sensor, integrated onto the implant, which is attached to the femur bone and which envelopes the femur bone, enabling to measure the force applied on the femur bone by implants providing the required force, and which also carries out the enveloping force that is required in order for the implant to be used efficiently.

Abstract: An expandable cage is placed between two vertebrae and expandable at a preferred ratio towards the vertebrae (i.e. in longitudinal axis). The expandable cage has at least one protrusion which is provided in the body and which, in case of a force being applied, forms a pointed tip out of the body, and at least one balloon which applies the required force to the protrusion such that the protrusion will move unilaterally.
