Abstract
The subject disclosure is directed to systems, apparatuses, devices and methods for vertebral and spinal correction. In some embodiments, an expandable implant is provided which may be inserted inside the vertebral body and/or between two vertebrae, for instance, for maintenance and/or restoration of a space therein or there between. In certain embodiments, the implant includes a mechanical resistance that prevents the expandable implant from contracting once it has been expanded. Methods of treatment and methods of use of such implants for the alleviation of back pain (for example) are also provided herein.
Claims48
A vertebral expandable implant, comprising:
- first and second bearing surfaces intended to move away from one another during expansion of the implant;
- at least first and second opposed ends associated with each of the bearing surfaces;
- and
- a retaining member for retaining the implant in an expanded configuration, wherein:
- the retaining element comprises a first end associated with the first end of the implant and a second end associated with the second end of the implant,
- a first engagement element provided proximate the second end of the retaining element for engagement with a second engagement element provided on the second end of the implant, wherein engagement between the first and second engagement element substantially prevents the second end of the implant from moving away from the first end of the implant.
An expandable implant, comprising:
- a first and second bearing surfaces, wherein the first and second surfaces are intended to move away from one another during expansion of the implant;
- at least first and second opposed end members associated with each of the bearing surfaces;
- a retaining element;
- and
- at least a pair of supports associated with at least one of the bearing surfaces, at least one of the bearing surfaces additionally associated with at least one of the end members, wherein a first support of the pair including a first engagement element, a second support of the pair including a second engagement element, and wherein upon expanding the implant a predetermined amount, at least a portion of the first engagement element engages with at least a portion of the second engagement element to prevent movement of the end members toward one another.
A method for restoring a space between two surfaces, comprising the steps of:
- inserting an expandable implant between two surfaces, wherein the expandable implant includes a contracted and an expanded configuration, and the implant comprises:
- first and second bearing surfaces intended to move away from one another according to a plane of expansion as the implant is expanded;
- first and second opposed end member associated with each of the bearing surfaces;
- and
- a retaining element for retaining the implant in an expanded configuration;
- positioning the implant between the two surfaces;
- and
- expanding the implant from the contracted configuration to the expanded configuration and thereby restoring the space.
A method for restoring a space between two surfaces, comprising the steps of:
- inserting an expandable implant, wherein the expandable implant includes a contracted and an expanded configuration, and the implant comprises:
- a first and second opposed plates, wherein the first and second plates are intended to move away from one another according to a plane of expansion as the implant is expanded;
- at least first and second opposed end members associated with each of the opposed plates, wherein at least one of the end members includes an aperture configured for receiving one end of a retaining element;
- a retaining element;
- and
- at least a pair of first and second supports associated with at least one of the first and second plates and additionally associated with at least one of the first and second end members, wherein at least one of the pair of the first and second supports comprises a first engagement element and a second engagement element for engagement with the first engagement element;
- positioning the implant between the surfaces;
- and
- expanding the implant from the contracted configuration to the expanded configuration and thereby restoring the space.
