Problems caused by late complications in patients undergoing prosthetic reconstruction after bone and soft tissue tumor surgery

Abstract

Radical surgery for malignant bone and soft-tissue tumors involves resection of the tumor as well as the adjacent bones, muscles, joints, and ligaments. In the case of tumor resection in which joint preservation is difficult, prosthesis is often used in reconstruction for function preservation and appearance. Late complications of reconstruction surgery include loosening of prosthesis and late infection. These complications occur frequently and are refractory to treatment. Considering the long treatment duration, the activities of daily living are substantially affected in children and young adults when late complications occur. Herein, we report two cases in which we treated refractory deep infection 10 or more years after tumor resection and prosthetic reconstruction for malignant bone and soft-tissue tumor and address issues related to such late complications.
