1. A method of correcting a spinal deformity comprising the steps of:
- inserting a device into an interior of a vertebral member;
expanding a size of the device and contacting the device against the interior of the vertebral member; and
applying an intraosseous expansile force on the vertebral member and causing the vertebral member to expand from a first size to a second size.

Abstract
The present application is directed to devices and methods for correcting a spinal deformity. One exemplary method comprises initially inserting a device into an interior of a vertebral member. The device may be a deformable material, or may be a mechanical apparatus. The device is then expanded in size such that it contacts against the interior of the vertebral member. The expanded device applies a force on the interior of the vertebral member that causes the member to expand from a first size to a second size. The process may include insertion into a single vertebral member, or multiple vertebral members along the spine.

12. A method of correcting a spinal deformity comprising the steps of:
-
forming a void within a concave side of an interior of a vertebral member; inserting a device into the void; expanding the device and contacting the device against superior and inferior sections of the void; applying an intraosseous expansile force against the superior and inferior sections of the void; and causing the concave side of the vertebral member to expand from a first height measured between inferior and superior endplates to a second greater height. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method of correcting a spinal deformity comprising the steps of:
-
forming a void within a concave side of an interior of the vertebral member; inserting a device into the void while the device is in a first state; activating the device; expanding the device within the void from the first state to a second state and applying an intraosseous expansile force to the vertebral member; and causing the concave side of the vertebral member to expand from a first height measured between inferior and superior endplates to a second greater height. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)

29. A method of correcting a spinal deformity comprising the steps of:
-
forming a void within a concave side of an interior of the vertebral member; inserting a material into the void while in a first state; exposing the material to an activation event; expanding the material within the void from the first state to a second state and applying an intraosseous expansile force to the vertebral member; and causing the concave side of the vertebral member to expand from a first height measured between inferior and superior endplates to a second height.
