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.
