Objective: To study the repair the curettage legacy of benign bone tumors and tumor-like lesions of bone defects clinical applications of calcium phosphate bone cement (CPC) value . Methods: The the CPC 33 bone defect repair 32 patients with benign bone tumors and tumor-like lesions after curettage legacy . The average age of the patients was 38 years old , including Fibrous dysplasia of the 10 cases , seven cases of giant cell tumor of bone lesion type , 6 cases of bone cyst , aneurysmal bone cyst in 6 cases , cartilage Fibroma one cases , non-ossifying tumor, osteoblastoma cases . The defect : 19 femur , 12 tibia , humerus 2 . Calcium phosphate cement (CPC) prefabricated cancellous bone particles and powder - harmonic type two formulations , this group is for powdered reconcile the two formulations mixed use . Microwave inactivation easy recurrence of giant cell tumor and osteoblastoma luggage to curettage fully scrape tumor surgery , then luggage surgery; the remaining bone tumors luggage curettage . Then the CPC powders and curing liquid evenly reconcile into a paste , CPC paste filling bone defect cavity and shaping . 8 cases of giant cell tumor and osteoblastoma CPC powder mixed with MTX. Four cases of giant cell tumor in the proximal tibia line gastrocnemius or lateral head muscle flap transfer to cover the front of the tibia . Observed in patients undergoing CPC curing time , postoperative systemic and local reactions in the incision , postoperative day , and two weeks of blood calcium, phosphorus value changes and liver and kidney function , and X -ray examination , the average follow-up time of 14 months ( follow-up 6 to 30 months). Results : In this study, observe the CPC powder curing liquid reconcile fill bone defects , a curing time of 15 to 30 minutes . All patients showed no systemic reaction , no increase of serum calcium , phosphorus value , two cases CPC incision of the proximal tibia of MTX in patients with giant cell tumor of bone the local once red , swollen , hot , obviously , increased incision oozing strengthen change drugs and other treatment , the incision is scheduled healing, one patient ( the CPC , including MTX) had mildly abnormal liver function , RAW , after the return to normal . Postoperative X -ray showed the bone missing
