RESUMO
Objective:To explore the long-term effect of hip replacement and vitamin D in treatment of elderly osteoporotic femoral neck fractures and the transfection of bone morphogenetic protein-7 (BMP-7) /25 hydroxy vitamin D3[ (25- (OH) ) -D3] level.Method:Data of 108 elderly osteoporotic femoral neck fracture patients admitted from Jan. 2018 to Jan. 2020 were selected, and they were divided them into the observation group (hip replacement adjuvant vitamin D treatment) and control group (hip replacement treatment) , 54 cases in each group. All subjects were followed up for 1 year to observe the long-term treatment efficacy and SF-36 scores of the two groups of patients. Before treatment and 1, 3, 6, and 12 months after treatment, the differences in the changes in lumbar and hip bone mineral density, hip joint Harris score, BMP-7, and 25- (OH) -D3 levels were compared between the two groups.Results:12 months after treatment, the long-term treatment effect of the observation group was significantly higher than that of the control group ( P<0.05) ; 1, 3, 6, 12 months after treatment, for the lumbar and hip bone mineral density, SF-36 score, hip Harris score, BMP-7, 25- (OH) -D3 levels of the two groups of patients over time, the degree of increase was not equal, but the treatment group had the greater degree of improvement ( P<0.01) . Conclusion:Hip joint replacement and vitamin D have a good long-term effect in treatment of elderly osteoporotic femoral neck fractures, which can significantly increase bone density and improve BMP-7 and 25- (OH) -D3 levels.
