Investigation of factors affecting loosening of ilizarov ring‐wire external fixator systems at the bone‐wire interface [PDF]

Journal of Orthopaedic Research, 2011
AbstractThe potential for peri‐implant bone yielding and subsequent loosening of Ilizarov ring‐wire external fixation systems was investigated using non‐linear finite element (FE) analyses. A strain‐based plasticity model was employed to simulate bone yielding.
