The development of the distal femur Less Invasive Stabilization System (LISS)

Fractures around the knee typically require operative fixation to achieve an acceptable, functional outcome. The idea behind the Less Invasive Stabilization System (LISS) was to combine the advantages of both interlocked intramedullary nailing techniques and the early advances of the so-called biological plating technique into one system. This paper introduces the mechanical concept of a locked internal fixator and details some important aspects of the anatomical and biomechanical development of the LISS.
