Title: Osteoporosis & Metabolic Bone Disease – Basic & Clinical Science Poster

Session Type: Poster Session (Tuesday)

Session Time: 9:00AM-11:00AM

Background/Purpose: A novel, non-ionizing approach – Radiofrequency Echographic Multi Spectrometry (REMS) was recently introduced for diagnosis of osteoporosis on both sites-lumbar spine and femoral neck. In the previous studies, bone mineral density (BMD) assessed by REMS technique highly correlated with BMD obtained by dual X-ray absorptiometry (DXA). However, there is no previous study, which investigated the diagnostic role of the dual femur BMD measurements based on REMS technology. The aim of this study is to compare the REMS-based BMD values of both femora-left and right in postmenopausal women and to identify the number of the women, in which the inclusion of bilateral hip in BMD measurement changed the diagnosis to more severe.

Methods: Dual femur was assessed in 72 postmenopausal women with mean age 61 years ± 13 standard deviations (SD), (range 40-66 years). Data was analyzed with SPSS version 21.0. Patients were classified as osteopenic if -2.5 SD < T-score< -1.0 SD, as osteoporotic if T-score ≤ -2.5 SD and healthy if T-score ≥-1.0. Linear regression analysis was used to compare the REMS-based BMD values of both femora.

Results: Based on the unilateral (left) hip BMD measurements, 22 women were diagnosed with normal BMD, 35- with osteopenia and 15 – with osteoporosis. The mean left femoral neck BMD was 0.879 g/cm2 ± 0.100 g/cm2 in the women with normal BMD, 0.685 g/cm2 ± 0.056 g/cm2 in the women with osteopenia and 0.507 g/cm2 ± 0.054 g/cm2 in the women with osteoporosis. The mean right femoral neck BMD was 0.873 g/cm2 ± 0.095 g/cm2 in the women with normal BMD, 0.677 g/cm2 ± 0.046 g/cm2 in the women with osteopenia and 0.507 g/cm2 ± 0.054 g/cm2 in the women with osteoporosis. A strong correlation between left and right femoral neck BMD values was observed (r2=0.978, p=0.000), (figure 1). 63.6% (14/22) of the women with normal BMD had a T-score discordance equal to 0.1 and 4.6% (1/22) – equal to 0.2. 31.8% (7/22) of the women with normal BMD were attributed to a more severe diagnosis – osteopenia after assessing the dual femur. 48.6% (17/35) of the women with osteopenia had a T-score discordance equal to 0.1, 8.6% (3/35) – equal to 0.2 and 2.9% (1/35) – equal to 0.5. 2.9% (1/35) of the women with osteopenia were attributed to a more severe diagnosis – osteoporosis after assessing the dual femur. 33.3% (5/15) of the women with osteoporosis showed a T-score discordance equal to 0.1.

Conclusion: In women with femoral neck BMD values, which correspond to borderline T-scores, dual femur BMD measurements could be crucial for obtaining a more accurate diagnosis and decision about the treatment.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
