Attachment device and method for use

A method for implanting an anatomical attachment device comprising:

• inserting the anatomical attachment device at least partially into a bone at a target site, wherein the attachment device has an attachment device lumen and an attachment device first fenestration in fluid communication with the attachment device lumen and the target site, and wherein a pressure reduction device is in the attachment device lumen, and wherein the pressure reduction device has a pressure reduction first fenestration;
• pressurizing a bone cement into the attachment device lumen, wherein the pressurizing comprises flowing bone cement through the attachment device lumen, then flowing the bone cement through the pressure reduction device first fenestration, then flowing the bone cement through the attachment device first fenestration, then flowing the bone cement into the target site;
• and
• wherein the pressure of the bone cement decreases when the bone cement passes through the pressure reduction first fenestration, and wherein the pressure reduction first fenestration is on a lateral side of the pressure reduction device, and wherein the pressure reduction device has a pressure reduction second fenestration on the lateral side of the pressure reduction device and at least 90° away from the pressure reduction first fenestration with respect to a longitudinal axis of the pressure reduction device.
