Abstract

A system for percutaneous fixation and stabilization of a fracture with a spanning, expandable structural frame placed in the intramedullary canal of the bone, comprising a column of surgical fluid such as bone cement, within which the structural frame acts as a reinforcing cage, and a sheath positioned at the fracture site and at least partially surrounding the frame and fluid. The fluid may be supported by a restrictor and may be agitated with a vibrating probe to remove entrapped air. The structural frame may be self-expanding or opened by an internal force, and it may be retrievable. The frame, fluid, or sheath may contain antibiotics, pharmaceuticals, or other therapeutic compounds to be delivered to the fracture site.
