Objective: To study the calcaneal quantitative ultrasound-bone mineral density (QUS-BMD) value for evaluating bone metabolism and bone turnover in patients with osteoporotic fracture. Methods: A total of 150 patients who were diagnosed with osteoporotic fracture in Nuclear Industry 417 Hospital between January 2010 and March 2017 were selected as the fracture group of the research, and 70 subjects with normal bone mineral density confirmed by physical examination during the same period were selected as the control group of the research. QUSBMD apparatus was used to measure bone mineral density of calcaneus, and the serum was collected to determine the biochemical indexes of bone metabolism and bone turnover. Results: QUS-BMD value as well as serum BALP, OC, OPG levels of fracture group was significantly lower than those of control group while serum TRACP5b, RANKL, PINP, PICP, CTX and NTX levels were significantly higher than those of control group; serum BALP, OC, OPG levels of patients with osteoporosis and osteopenia were significantly lower than those of subjects with normal bone mass while TRACP5b, RANKL, PINP, PICP, CTX and NTX levels were significantly higher than those of subjects with normal bone mass; serum BALP, OC, OPG levels of patients with osteoporosis was significantly lower than those of patients with osteoporosis while TRACP5b, RANKL, PINP, PICP, CTX and NTX levels were significantly higher than those of patients with osteoporosis. Conclusion: Calcaneal QUS-BMD is valuable for evaluating the bone metabolism activity and bone turnover process in patients with osteoporotic fracture. |
