TRANSPOSITION OF A VASCULARIZED DISTAL FEMORAL BONE-GRAFT AFTER WIDE RESECTION OF A DIAPHYSEAL EWINGS-SARCOMA - A SALVAGE PROCEDURE

We report a case of a 26-year-old woman with a surgical stage IIb lesi on of Ewing's sarcoma of the left femur diaphysis. After intracompartm ental wide resection a custom-made diaphyseal spacer was inserted for optional secondary biological reconstruction. Treatment-associated com plications such as loosening of the implant and a septic process made a limb-preserving procedure impossible, and therefore a salvage proced ure with transposition of the vascularised distal femur as a graft for lengthening of the short proximal femur was necessary. This unfortuna te course is an example of limb-salvage surgery that not infrequently leads to reoperations or ultimately an amputation. Therefore individua l surgical procedures have to be considered to provide the best limb f unction.
