Methods for treating a fractured and/or diseased and/or weakened bone

摘要

A percutaneous access path into a vertebral body is established. The vertebral body has an interior volume occupied, at least in part, by a cancellous bone. At least portion of the cancellous bone is compacted or otherwise conditioned, resulting in a cavity in the vertebral body. A bone filler material is conveyed into the cavity at a pressure less than approximately 400 pounds per square inch. The bone filler material can have a viscosity that resists extravazation in cancellous bone.
