Expandable support device and method of use

A method of performing surgery in a patient comprising:

• accessing a bone structure;
• forming an opening into the bone structure;
• inserting an expandable implant having a body having a length, width and height defining a substantially hollow interior, the implant further including at least one first strut defining one of said height or width, said first strut being substantially deformable under expansion force to alter a dimension of the implant, the first strut having a first, unexpanded configuration and a second expanded configuration, the implant increasing in dimension in the direction of expansion of said first strut;
• and
• expanding the implant to deform the first strut, thereby expanding the implant within the bone structure, wherein the expanding comprises deforming the first strut, and wherein expanding comprises expanding in an inferior-superior direction with respect to the patient;
• wherein the implant further comprises sliding wedges.
