摘要：
An apparatus includes an elongate body and an expandable member coupled to the elongate body. In one embodiment, the expandable member has a collapsed configuration, an unfolded configuration and an expanded configuration. The expandable member is configured to be percutaneously inserted into an interior portion of a bone structure when the expandable member is in the collapsed configuration. The expandable member is configured to exert a pressure in a vertical direction on a first portion of the bone structure in contact with the expandable member greater than a pressure exerted in a lateral direction on a second portion of the bone structure in contact with the expandable member when the expandable member transitions from the unfolded configuration to the expanded configuration.
