The three sites addressed included an ultradistal (U) region containing approximately 60% trabecular bone. The other sites, distal (D) and shaft (S), were progressively more cortical. Reproducibility was 1.7\u20131.9% CV. The earliest evidence of a significant correlation between BMD and years since menopause was seen in trabecular bone in subjects aged 45\u201355 years. Fractional decrease in BMD, relative to the premenopausal value, was significantly larger at U than at S for the decades 55\u201365 years and above. Fractional rates of bone loss at all sites were a maximum in the first postmenopausal decade, the rate at U being 0.035, approximately 1.5 times that at D or S. A total of 33 subjects reported 54 previous minimally traumatic nonaxial (MTNA) fractures. When BMD measurements of the entire study were divided into quintiles, the prevalence of MTNA fracture cases in the lowest quintile was eight times that of each of the upper three quintiles. Prevalence of fracture cases ranked by quintiles of BMD were not different for the three scan sites. Therefore, ultradistal measurements confer no advantages over distal or shaft BMD for discriminating past MTNA fracture cases but do show larger fractional rates of loss during the first postmenopausal decade. When early postmenopausal women (with years since menopause \u2264 10) having BMD at U below the 15th age-corrected percentile, and their high BMD peers above the 75th percentile, were studied prospectively over 9\u201324 months there were no differences in their mean fractional rates of bone loss. These rates confirmed cross-sectional measurements based on years since menopause \u2264 10 but without selection for BMD.<\/jats:p>","DOI":"10.1002\/jbmr.5650040204","type":"journal-article","created":{"date-parts":[[2010,2,3]],"date-time":"2010-02-03T18:09:26Z","timestamp":1265220566000},"page":"149-155","source":"Crossref","is-referenced-by-count":32,"title":["Ultradistal and cortical forearm bone density in the assessment of postmenopausal bone loss and nonaxial fracture risk"],"prefix":"10.1093","volume":"4","author":[{"given":"Roger I.","family":"Dr. Price","sequence":"first","affiliation":[{"name":"Department of Endocrinology and Diabetes, Sir Charles Gairdner Hospital, Verdun Street, Nedlands, Western Australia 6009"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marion P.","family":"Barnes","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Diabetes, Sir Charles Gairdner Hospital, Verdun Street, Nedlands, Western Australia 6009"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donald H.","family":"Gutteridge","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Diabetes, Sir Charles Gairdner Hospital, Verdun Street, Nedlands, Western Australia 6009"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margaret","family":"Baron-Hay","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Diabetes, Sir Charles Gairdner Hospital, Verdun Street, Nedlands, Western Australia 6009"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard L.","family":"Prince","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Diabetes, Sir Charles Gairdner Hospital, Verdun Street, Nedlands, Western Australia 6009"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert W.","family":"Retallack","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Diabetes, Sir Charles Gairdner Hospital, Verdun Street, Nedlands, Western Australia 6009"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caroline","family":"Hickling","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Diabetes, Sir Charles Gairdner Hospital, Verdun Street, Nedlands, Western Australia 6009"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[1989,4,1]]},"reference":[{"key":"2024012712285129900_bib1","doi-asserted-by":"crossref","first-page":"323","DOI":"10.3109\/00365517509095748","article-title":"Bone mineral content in the forearm measured by photon absorptiometry","volume":"35","author":"Christiansen","year":"1975","journal-title":"Scand J Clin Lab Invest"},{"key":"2024012712285129900_bib2","first-page":"1241","article-title":"Assessment of bone mineral.
