A device, system, and method for reinforcing a femoral neck bone comprises a support structure deployable from a first substantially collapsed position to a second substantially expanded position within a cancellous bone area of the femoral neck. The support structure compresses at least a portion of the cancellous bone upon expansion. A cavity created by the expansion is adapted to receive a filler material such as, but not limited to, bone cement. Upon final positioning and curing, the support structure and any filler material is adapted to interact with the healthy cortical bone and/or compressed cancellous bone and receive at least a portion of a load placed on the femoral neck bone.
