1. A method for treating bone comprising:
inserting a pressure reduction device at least partially into a bone at a target site, wherein the pressure reduction device has a pressure reduction device lumen, a pressure reduction first fenestration, and a pressure reduction second fenestration, wherein during the inserting, a longitudinal center of the pressure reduction device lumen has a transverse width, wherein the pressure reduction first fenestration is proximal to the pressure reduction second fenestration, wherein the pressure reduction device comprises a mesh, wherein the pressure reduction first and second fenestrations are in the mesh, and wherein the mesh extends around a perimeter of the pressure reduction device lumen; and
flowing bone cement through the pressure reduction device lumen when the longitudinal center of the pressure reduction device lumen has the transverse width, then flowing the bone cement through the pressure reduction first fenestration, then flowing the bone cement into the target site,
wherein a pressure of the bone cement decreases when the bone cement flows through the pressure reduction first fenestration, wherein the pressure reduction first fenestration is on a lateral side of the pressure reduction device, and
wherein the pressure reduction device is insertable in a bone screw having a bone screw fenestration having a bone screw fenestration length, wherein the mesh has a mesh length, and wherein the mesh length is greater than the bone screw fenestration length.
