Abstract:
Objectives:To evaluate the role of trabecular bone score (TBS), in addition to bone mineral density (BMD), and to aid decision making to initiate anti-osteoporotic treatment in postmenopausal women with osteopenia.
Methods:TBS was assessed in a cohort of Thai postmenopausal women with BMD of femoral neck (FN), total hip (TH), and lumbar spine (LS) performed at the Police General Hospital, Bangkok, Thailand from July 2019 to October 2020. We retrospectively reviewed hospital database for underlying diseases, medication, and fractures, including relevant imaging and vertebral fracture assessment (VFA). Patients with previous osteoporosis treatment, skeletal malignancy, high-energy trauma, and uninterpretable BMD were excluded.
Results:In total there were 407 postmenopausal women, including 115 with osteoporotic fractures. The mean TBS of the cohort was 1.264 ± 0.005. The proportion of osteoporotic subjects ranged from 9.1% by TH BMD to 27.0% by lowest BMD. In fractured patients, 21.7%e54.8% were found to have osteoporosis while osteopenia was found in 37.4%e43.5%. Among subjects with osteopenia and degraded TBS, fractures ranged from 21.7 to 50.9%. Addition of osteopenic subjects with degraded microarchitecture yielded a significantly higher number of subjects eligible for treatment with 3.25-fold increase in non-fractured participants, and 7 to 11 additional osteopenic patients should be treated to detect 1 fracture.
Conclusions:Addition of TBS helped capturing osteopenic women with high risk of fracture. Decision to treat osteopenic women with degraded TBS increased the number of patients receiving treatment. We recommend evaluating TBS in osteopenic women without fractures to aid therapeutic decision on treatment initiation.
