AbstractPathological fractures of long tubular bones are stabilized with conventional implants. Essentially, plates and intramedullary nails are used for stabilization and are two different techniques, which compete with each other with respect to the surgical treatment. A large number of such means of osteosynthesis are commercially available but are primarily focused on acute fractures in otherwise biologically healthy bones. The pathological fracture or the treatment of impending pathological fractures due to metastatic osteolysis differs from the treatment of healthy bones in some fundamental aspects. The characteristics of pathological fractures make the development of new technologies that meet the specific needs of both the patient and the surgeon desirable. A new approach in treatment is stabilization of internal long bone fractures by the use of a cylindrical balloon implant, which is introduced into the bone via a small proximal or distal hole and then filled and expanded to a much larger diameter with a liquid monomer. The curing process is initiated with the application of blue light forming a rigid implant by polymerization (IlluminOss™). Many of the well-known disadvantages of conventional implants can be eliminated with this technology. Specifically, with respect to the irregular shape of the natural medullary canal it is possible to completely fill the medullary canal of the tubular bone. The filling of the canal provides torsional stability without the use of interlocking screws. Similarly, the use of the balloon technique enables minimally invasive surgery and furthermore permits the additive use of conventional metallic plates whenever necessary. The new balloon techniques show high primary stability in the treatment of pathological shaft fractures. In particular cases, the addition of a supplemental plate osteosynthesis is recommended.
