Methods and apparatuses for bone restoration
Methods and apparatuses for restoration of human or animal 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 out 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.
1. An expansible implant for bone restoration comprising:
a single plane of expansion intrinsic to the implant, wherein the single plane of expansion corresponds to a bone restoration plane;
first and second opposed plates respectively forming first and a second bearing surfaces for the bone, wherein the first and second plates move away from one another according to the single plane of expansion at the time of the expansion of the implant;
first and second implant ends substantially aligned along a longitudinal axis of the implant, wherein the first implant end includes an opening for allowing engagement of the implant with an implant carrier;
at least one pair of first and second supports, wherein each support of a pair of supports includes a first end connected to the first or second plate and a second end connected to the first or second implant ends; and
a first material web provided between each respective support and the corresponding plate the support is connected to, and
a second material web provided between each respective support and the corresponding implant end the support is connected to, wherein
each material web plastically deforms during expansion of the implant to control expansion of the implant, and wherein each material web comprises a reduced thickness portion of a respective support.
2. A method for restoration of human or animal bone anatomy, comprising:
introducing, into a bone, an expansible implant having:
a single plane of expansion;
at least one plate forming a bearing surface for bone, wherein upon expansion of the implant, the plate is directed away from a longitudinal axis of the implant according to the single plane of expansion at the time of the expansion of the implant;
first and second implant ends substantially aligned along the longitudinal axis of the implant, wherein the first implant end includes an opening for allowing engagement of the implant with an implant carrier;
at least one support connected to at least one plate and at least one implant end; and
a zone of material provided between the at least one support and at least one of the at least one plate and the at least one implant end, wherein
the zone of material plastically deforms during expansion of the implant for controlling the expansion of the implant, and wherein the zone of material comprises a reduced thickness portion of a respective support;
positioning the expansible implant in the bone in order to correspond the single plane of expansion with a bone restoration plane, and
expanding the implant in the bone restoration plane.
