Whether trabecular bone score (TBS) additionally identifies patients who benefit from parathyroidectomy in terms of bone health is unknown.

After parathyroidectomy, BMD at lumbar spine (LS) improved by 6.7% (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) while TBS did not change. Among women, peak preoperative parathyroid hormone and calcium levels independently predicted LS BMD gain. Among women with BMD in non\u2010osteoporotic range, LS BMD also improved after parathyroidectomy, where preoperative TBS was the only significant variable inversely correlating with percentage change in LS BMD (<jats:italic>\u03c1<\/jats:italic>\u2009\u2212\u20090.775, <jats:italic>p<\/jats:italic>\u2009=\u20090.005).
