Systems and methods for treating fractured or diseased bone using expandable bodies

Abstract

Systems and methods treat fractured or diseased bone by deploying more than a single therapeutic tool into the bone. In one arrangement, the systems and methods deploy an expandable body in association with a bone cement nozzle into the bone, such that both occupy the bone interior at the same time. In another arrangement, the systems and methods deploy multiple expandable bodies, which occupy the bone interior volume simultaneously. Expansion of the bodies form cavity or cavities in cancellous bone in the interior bone volume.

No. 08 / 485,394, filed Jun. 7, 1995, which is a continuation-in-part of U.S. patent application Ser. No. 08 / 188,224, filed Jan. 26, 1994 entitled, “Improved Inflatable Device For Use In Surgical Protocol Relating To Fixation Of Bone.”FIELD OF THE INVENTION [0002] The invention relates to the treatment of bone conditions in humans and other animals. BACKGROUND OF THE INVENTION [0003] When cancellous bone becomes diseased, for example, because of osteoporosis, avascular necrosis, or cancer, the surrounding cortical bone becomes more prone to compression fracture or collapse. This is because the cancel...

AI Technical Summary

Benefits of technology

This approach effectively compacts cancellous bone, forms cavities to stabilize cortical bone, and injects filling materials to enhance bone integrity, reducing the risk of fractures and deformities, thereby improving treatment outcomes for bone diseases.

Problems solved by technology

When cancellous bone becomes diseased, for example, because of osteoporosis, avascular necrosis, or cancer, the surrounding cortical bone becomes more prone to compression fracture or collapse.

This is because the cancellous bone no longer provides interior support for the surrounding cortical bone.

These conditions, if not successfully treated, can result in deformities, chronic complications, and an overall adverse impact upon the quality of life.
