Endoprosthetic replacement of segmental skeletal defects is now the preferred technique of reconstruction after resection of bone sarcomas. As experience has grown, the indications for endoprosthetic replacement have expanded to include revision of failed total joint replacement, treatment for chronic osteomyelitis, and revision of failed allografts. A major advantage of a modular endoprosthetic system is inoperative flexibility; it enables the surgeon to reconstruct defects of any size with minimal preoperative planning. Instead of performing a resection to match a prosthesis customized on the basis of imaging studies that are 1 to 2 months old, the surgeon can concentrate onperforming the best possible resection indicated for the patient at the time of surgery. This article reviews the indications and techniques for reconstructing the soft tissues after implantation of a modular endoprosthesis to optimize the functional outcome.
