Limb-sparing surgery for distal femoral and proximal tibial bone lesions: imaging findings with intraoperative correlation.

ABSTRACT

OBJECTIVE: Our purpose is to present normal and abnormal imaging findings associated with endoprosthetic reconstruction after limb-salvage surgery. CONCLUSION: Endoprosthetic reconstruction varies with the location and size of the tumor, implant designs, and complications. Radiologists need to be aware of associated imaging findings seen in postoperative infection, tumor recurrence, and hardware failure. With a thorough understanding of the normal postoperative radiographic findings after complex reconstructions, subsequent abnormalities are readily identified and timely diagnosis can be obtained.
