Summary: | Summary
The trabecular bone score (TBS) is an indirect measure of vertebral bone microarchitecture. Our objective was to examine the effect of testosterone treatment on TBS. One hundred and ninety-seven hypogonadal men were randomized to testosterone or placebo. After 12 months, there was no difference in the changes in TBS by randomized group.
Introduction
In the Bone Trial of the Testosterone Trials, testosterone treatment increased trabecular volumetric bone mineral density (vBMD) and increased estimated bone strength as determined by finite element analysis. The trabecular bone score (TBS) is an indirect measure of vertebral bone microarchitecture. TBS predicts fracture independent of lumbar spine areal (a) BMD. The objective of this study was to examine the effect of testosterone treatment on TBS compared to its effects on vBMD and aBMD.
Methods
Two hundred and eleven men were enrolled in the Bone Trial of the Testosterone Trials. Of these, 197 men had 2 repeat TBS and vBMD measurements; 105 men were allocated to receive testosterone, and 92 men to placebo for 1 year. TBS, aBMD, and vBMD were assessed at baseline and month 12.
Results
There was no difference in the percent change in TBS by randomized group: 1.6% (95% confidence intervals (CI) 0.2–3.9) in the testosterone group and 1.4% (95% CI −0.2, 3.1) in the placebo group. In contrast, vBMD increased by 6% (95% CI 4.5–7.5) in the testosterone group compared to 0.4% (95% CI −1.65–0.88) in the placebo groups.
Conclusions
TBS is not clinically useful in monitoring the 1-year effect of testosterone treatment on bone structure in older hypogonadal men. |
