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

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