Bone treatment systems and methods

摘要

Methods and instruments for treating an osteoporotic vertebral body or for treating a vertebral compression fracture. An exemplary method includes introducing an open knit structure together with a bone cement into a bone wherein the knit structure extends substantially throughout the interior of the cement volume. In one aspect of the invention, the bone cement volumes cures with the filament structure reinforcing the cement. In another aspect of the invention, the open knit structure is configured to direct flows of bone cement to apply forces for reducing a vertebral compression fracture. In another aspect of the invention, the system provides bone cement flows that extend through the knit structure thus allowing the cement to fully interdigitate with the cancellous bone.

主权项

1. A method of directing a flow of a bone fill material in a bone, comprising:
providing a knit structure comprising a plurality of spaced apart conductive filaments and a plurality of openings; introducing the knit structure and a volume of bone cement into a bone, wherein the plurality of openings in the knit structure at least partly direct flow of the volume of bone cement; and applying electrical or electromagnetic energy to the plurality of spaced apart conductive filaments, wherein the plurality of spaced apart conductive filaments function as an electrode for altering the viscosity of the volume of bone cement.
