The dual incision surgical approach for total femur resection and endoprosthesis reconstruction in patients, with femur bone sarcoma: A case series

Introduction: Limb preservation following the excision of tumors that involve the entire femur provides a therapeutic hurdle. Bone sarcomas involving almost the whole femur necessitate radical excision which encompasses removal of the entire femur bone, along with significant resection of the muscles involved in hip and knee function. Traditionally, surgical treatment of large femoral tumors required amputation via hip disarticulation, however, newer methods of preserving the limb, namely, Total Femur Replacement (TFR), have emerged. In comparison to amputation, limb preservation surgery is more cost-effective and better tolerated by patients. In the long run, it is associated with much lower oxygen use and energy requirements per meter walked.
