A vertebral augmentation system comprising a biocompatible mesh sheet having a first end and a second end. The mesh sheet includes a plurality of first strands having a first maximum extension intertwined with a plurality of second strands having a second maximum extension. The mesh sheet also includes a first interface portion adapted to contact a first vertebral bone and a second interface portion adapted to contact a second vertebral bone. The plurality of first strands have a greater elasticity than the plurality of second strands, and the plurality of second strands limit the plurality of first strands from reaching the first maximum extension when the first vertebral bone moves relative to the second vertebral bone.
