Ilizarov external fixator for stump salvage in infected nonunions.
Infected nonunions are potentially difficult complications to treat in the context of complex tibial fractures. Often, such complications necessitate amputation to prevent further sequelae, such as fulminant sepsis and complete loss of the limb. As such, the eradication of infection, the decision regarding when to amputate, and the length of the residual stump are important factors to optimize patient outcome. The authors present a unique scenario whereby an Ilizarov external fixation device was used to treat an infected tibial nonunion while simultaneously salvaging stump length to enable fitting for a below-knee prostheses. The use of the Ilizarov device can prevent abrupt dissemination of infection, stabilize the fracture, and bridge nonunion gaps. This is augmented by the unique ability of the construct to be periodically readjusted and realigned where needed to permit osteogenesis and proper alignment. The result in this case was complete eradication of infection, with the use of continuous antibiotics as a pharmacological adjunct, union of the tibial fragments, and a below-knee amputation with adequate stump length and prosthetic fit. The success of this treatment strategy was predicated on the above factors, with an emphasis on amputation level and its effect on function. The Ilizarov external fixator is a device that has been widely used to treat limb-length discrepancies, correct deformities, and induce osseous growth in bony nonunion. The authors present the Ilizarov device as a viable option for the treatment of infected tibial nonunions and stump length salvage.
