Abstract
Methods and apparatuses for restoration of human or bone anatomy, which may include introduction, into a bone of an expansible implant capable of expansion in a single determined plane, positioning the expansible implant in the bone in order to correspond the single determined plane with a bone restoration plane and opening our the expansible implant in the bone restoration plane. A first support surface and a second support surface spread tissues within bone. The embodiments of the invention may also include injecting a filling material around the implant.

(canceled)
A method for restoration of a human or animal vertebral body comprising:
- implanting an implant into a vertebral body;
- moving integrally connected first and second plates of the implant in opposite directions of each other and orthogonal to a longitudinal axis of the implant;
- and
- injecting a filling material through the implant and into the cavity such that the filling material at least partially surrounds the implant.
A method for restoration of a human or animal vertebral body comprising:
- introducing an implant into a vertebral body;
- expanding a unitary structure of the implant, the unitary structure including a first plate and a second plate,
- wherein the first plate expands in a first direction directly orthogonal to a longitudinal axis of the implant, and
- wherein the second plate expands in a second direction directly orthogonal to the longitudinal axis of the implant, the second direction being opposite to the first direction;
- and
- injecting a filling material through the implant and into the cavity containing the implant while the implant remains disposed in the vertebral body.
A method for restoration of a human or animal vertebral body comprising:
- introducing an implant into a vertebral body, the implant comprising:
- a first end element and a second end element, each centered on a longitudinal axis of the implant;
- a first plate and a second plate each positioned between the first end element and the second end element when the implant is in a collapsed position;
- and
- a first support arm extending from the first end element to the first plate and a second support arm extending from the first end element to the second plate;
- simultaneously expanding the first plate and the second plate from the collapsed position to an expanded position through rotation of the first support arm and the second support arm, respectively,
- wherein the first plate expands in a first direction directly orthogonal to the longitudinal axis of the implant, and
- wherein the second plate expands in a second direction directly orthogonal to the longitudinal axis of the implant, the second direction opposite the first direction;
- and
- injecting a filling material through the implant and into the cavity containing the implant while the implant remains disposed in the vertebral body.
