Purpose: This study was performed to evaluate the efficiency of Hydroxyapatite (Bongros®-HA) what use for bone defect after operative treatment of benign bone tumor.
Materials and Methods: Hydroxyapatite, was used to treat bone defect after operative treatment of benign bone tumor from September, 2006 to December, 2007. A total of 17 benign bone tumor cases (10 males and 7 females) with mean age of 28.5 was observed studied. The diagnoses were fibrous dysplasia in 8 cases, solitary bone cyst in 5 cases, and giant cell tumor in 4 cases. In categorization by location of tumor, there were 6 cases of proximal femur, 3 cases of proximal femur, 3 cases of proximal tibia, 4 cases of proximal humerus, and 1 case of hip bone. Autogenous bone was used with Hydroxyapatite in 4 cases, and only Hydroxyapatite used in 13 cases. Periods of Follow-up were from 3 months to 15 months, and mean period were 7.5 months. Amount of graft resorption and bone formation was observed with compare of post operation radiograph and the difference was shown by percentage.
Results: More than 98% bone uptake was observed after mean 4.5 months, and more than 98% bone formation was observed after mean 6.2 months. Lesser bone defect size showed faster bone formation and it was statistically significant result (P=0.012). But other comparative studies on other factors such as sex, age of patients and combination of autogenous bone were no statistically significant differences in graft resorption and bone formation. And there was no significant complications in periods of follow-up.
Conclusion: Hydroxyapatite is considered as one of useful method of bone defect after operative treatment of benign bone tumor.
