||Retrospective study for the change of bone density over 2 years in patients at Sorokdo hospital
Seung-Kyu Park Surgical Dept., National Sorokdo Hospital
Introduction : Author investigated the baseline of BMD and T-score through analysis of bone density for 254 ex-hansen patients in 2014. This study aims to evaluate the change of BMD and T-score after two years of medication to improve the BMD of those patients. Materials and Methods : The 144 subjects received the tests for bone density at 2015 and 2016 consecutively and have taken medication since 2014. DXA machine was used on L1-L4 and femur neck and the results of BMD and T-score were compared with those in 2014. Results : The rate of male to female was 1:1.08, their mean age was 77.3 years old. In comparison with the results of 2014, the change of BMDs(g/cm2) at femur neck were 쭯 0.08 in 60s, -0.11 in 70s, and 쭯0.09 in 80s and older. For the change of T-score, they showed 쭯0.70 in 60s, -0.81 in 70s, and 쭯1.30 in 80s and older. But the BMDs at femur neck in 2016 increased by 0.04 in 60s and 0.01 in 80s and older. Conclusion : Both of the bone densities and T-scores at femur neck were decreased comparing with those of 2014. But the change of BMDs between 2015 and 2016 was almost absent. So, the effect of long term medication with bisphosphonate was thought to be effective for improving BMDs in old ex-hansen patients at national Sorokdo hospital.
