Abstract
In addition to the conventional stabilisation procedures, new trends with reduced operation trauma achieve acceptance concerning the treatment of supra- and interkondylar (C-)fractures of the distal femur. Retrograde intramedullary nailing techniques provide advantages in regard to centre line of weight bearing, bone loss of the distal metaphysis and the periosseous blood supply. By the development of a new retrograde nail with diagonal intersecting distal interlocking bolts the indication spectra is extended. Anatomical examinations, implantations in cadaver femora and three-dimensional CT computer simulations were used to optimise the nail features and to reduce implantation failures.
