RAZIONALE ED EFFICACE SISTEMAZIONE EXTRAMIDOLLARE DI STRUMENTI PARTICOLARMENTE DESTINATA ALLA ESECUZIONE DEL TAGLIO DISTALE FEMORALE DURANTE ARTROPROTESI TOTALE DI GINOCCHIO

摘要

The instrument has distance blocks and cutting slot blocks arranged on a carrier and retaining geometrical characteristics of a sagittal plane of a distal femur shaft even in a level of a pineal gland of a femur. Positions of the cutting slot blocks are changed by the distance blocks and/or sliding guides. Positions of platforms of the distance blocks staying in contact to condyles are in variable alignment relative to a central body of the instrument for following an alignment of the condyles. The platform lies at a point of convexities of the condyles.
