Management of a nonunion of the distal femur in osteoporotic bone with the internal fixation system LISS (less invasive stabilization system)

摘要

We present a case illustrating the successful use of the internal fixation LISS in an osteoporotic nonunion of the distal femur, where classic osteosynthesis has failed. The LISS plate with its angular stability offered the possibility to achieve excellent purchase in the severely porotic and partially destroyed bone. In combination with the use of an autologeous bone graft laterally and a strut cortical autograft medially, a mechanical support and an osteoinductive stimulus was provided and the extremity could be saved by this procedure.
