    • An apparatus according to the invention may comprise one or more expandable structural support pylons (140), means for deploying said one or more structural support pylons (138, 141), and one or more therapeutic substances. Structural support pylons (20) may comprise an elastomeric core (22), or may comprise one or more suitable metals, and may be deployed by shortening the length and increasing the height of the pylon. Alternatively, scaffold (200) may comprise a delivery configuration in which first unit (202) and second unit (204) he generally end to end, and a deployed configuration in which superior surfaces (216) and (218) exert an upward force and inferior surfaces (220) and (222) exert a downward force on superior and inferior vertebral surfaces respectively. A method according to the invention may comprise accessing an interior of a diseased or injured bone in a minimally invasive manner, creating a semi-circular path within said bone, deploying one or more structural support pylons within said interior, introducing structural reinforcement material, and if desired, repeating with one or more subsequent structural support pylons.
    • 根据本发明的装置可以包括一个或多个可膨胀结构支撑塔(140),用于展开所述一个或多个结构支撑塔(138,141)的装置和一个或多个治疗物质。 结构支撑塔(20)可以包括弹性体芯(22),或者可以包括一种或多种合适的金属,并且可以通过缩短长度和增加塔的高度来展开。 或者,脚手架(200)可以包括其中大致端对端的第一单元(202)和第二单元(204)以及上表面(216)和(218)施加向上的力的展开构造的输送构型, 下表面(220)和(222)分别在上下椎体表面上施加向下的力。 根据本发明的方法可以包括以微创方式进入患病或受伤的骨骼的内部,在所述骨骼内产生半圆形路径,在所述内部内展开一个或多个结构支撑塔,引入结构增强材料,以及 如果需要,用一个或多个随后的结构支撑塔重复。
