MODULAR ENDOPROSTHETIC REPLACEMENT AFTER TOTAL RESECTION OF THE FEMURFOR MALIGNANT-TUMOR

Seven patients underwent total resection of the femur with replacement by the Kotz modular femur and tibia reconstruction system (KMFTR); th ree of these operations were for primary malignant tumours and four we re salvage procedures after failed limb-sparing surgery. Clinical and radiological results were excellent or good at final follow up at an a verage of 23 months. A new method of radiological assessment has been used for the acetabular component of bipolar hip endoprosthesis. The p olyethylene bush of the hinged knee component may wear. Reattachment o f the abductors to the endoprostheses often fails and we now suture th e abductors to the fascia lata. The rectus femoris muscle should be sa ved, if possible, after resection. When total excision of the quadrice ps is indicated, the knee should be arthrodesed. The KMFTR is easy to use and has provided good medium to long term results in our cases.
