BACKGROUND: The aim of this study was to analyze the correlations of serum hormones and bone mineral density (BMD) with fracture and balance ability of postmenopausal patients and effects of calcitriol on them.

MATERIAL AND METHODS: The clinical data of 164 postmenopausal female patients with osteoporosis (OP) treated in our hospital were retrospectively analyzed.

RESULTS: The incidence rates of OVCF, balance index score (BIS), front-back ratio (FBR), and right-left ratio (RLR) in the normal BMD group, reduced BMD group, and OP group showed increasing trends, and there were statistically significant differences in comparisons among groups (p<0.05). The levels of serum estradiol (E2) and progesterone (P) in the OVCF group were lower than those in the non-OVCF group, and there were statistically significant differences in comparisons between the 2 groups (p<0.05). However, there was no statistically significant difference in the comparison of serum luteinizing hormone (LH) level between the 2 groups (p>0.05). BIS, FBR, and RLR were negatively correlated with E2 and testosterone (T) (p<0.05). With the prolongation of calcitriol treatment time, BIS, FBR, and RLR gradually decreased, but T value gradually increased. At 6 months and 12 months after intervention, BIS, FBR, and RLR had significant differences compared to those before the experiment (p<0.05). (5) Total hip BMD, height, age, and body mass index (BMI) were the independent factors affecting SDI.

CONCLUSIONS: Hip BMD, age, height, and BMI are significantly correlated with OVCF. Calcitriol treatment can increase lumbar BMD and improve balance ability, and these effects become more obvious with prolongation of intervention time.
