摘 要:BACKGROUND In children with osteosarcoma around the knee joint without epiphysis involvement,joint-sparing surgery seems to be an ideal way to retain knee joint ***,there are two points of debate with regard to the technique:How to accurately achieve a safe surgical margin,and how to achieve intercalary reconstruction of the massive bone defect following resection of the *** SUMMARY We present the case of an 8-year-old girl with osteosarcoma of the distal femur without involvement of the *** distraction was applied to separate the epiphysis and metaphysis,and this provided a safe surgical *** massive bone defect was reconstructed with a custom-made antibioticloaded polymethyl methacrylate(PMMA)construct combined with a free nonvascularized fibular *** months after surgery,bone union between the autograft and host bone was confirmed in both the proximal and distal femur by computer tomography(CT)***,considerable callus formation was found around the PMMA *** 28 mo of follow-up,there was no sign of recurrence or *** patient could walk without any aid and carry out her daily life activities *** In cases of osteosarcoma without epiphysis involvement,epiphyseal distraction can be easily applied to obtain a safe *** reconstruction with an antibiotic-loaded PMMA construct combined with a free non-vascularized fibular graft has the advantages of being easy to manufacture,less time-consuming to place,and less likely to get infected,while also ensuring bone *** case provides an alternative technique for biological reconstruction after joint-sparing surgery in patients with osteosarcoma around the knee without epiphyseal involvement.
