    Bone area is one measure of bone size that is easily derived from dual-energy X-ray absorptiometry (DXA) scans. In a GWA study of DXA bone area of the hip and lumbar spine (N ≥ 28,954), we find thirteen independent association signals at twelve loci ...

    Segulómun við greiningu lendahryggsverkja: Nýting, samband við einkenni og áhrif á meðferð 
    Svanbergsson, Gunnar; Ingvarsson, Þorvaldur; Arnardóttir, Ragnheiður Harpa (Laeknabladid/The Icelandic Medical Journal, 2017-01-05)
    Background: Non-specific low-back pain is a worldwide problem. More specific diagnosis could improve prognosis. Magnetic resonance imaging (MRI) became available in Akureyri Hospital in 2004 but its utilisation in diagnosing low-back pain has not been ...

    Sequence variants in the PTCH1 gene associate with spine bone mineral density and osteoporotic fractures 
    Styrkarsdottir, Unnur; Thorleifsson, Gudmar; Gudjonsson, Sigurjon A.; Sigurdsson, Asgeir; Center, Jacqueline R.; Lee, Seung Hun; Nguyen, Tuan V.; Kwok, Timothy C.Y.; Lee, Jenny S.W.; Ho, Suzanne C.; Woo, Jean; Leung, Ping-C.; Kim, Beom-Jun; Rafnar, Thorunn; Kiemeney, Lambertus A.; Ingvarsson, Þorvaldur; Koh, Jung-Min; Tang, Nelson L.S.; Eisman, John A.; Christiansen, Claus; Sigurdsson, Gunnar; Thorsteinsdottir, Unnur; Stefansson, Kari (Springer Science and Business Media LLC, 2016-01-06)
    Bone mineral density (BMD) is a measure of osteoporosis and is useful in evaluating the risk of fracture. In a genome-wide association study of BMD among 20,100 Icelanders, with follow-up in 10,091 subjects of European and East-Asian descent, we found ...

Mark; Meulenbelt, Ingrid; Michael Lee, Ming Ta; Styrkársdóttir, Unnur (2022-08-01)
    Objectives: Observational analyses suggest that high bone mineral density (BMD) is a risk factor for osteoarthritis (OA); it is unclear whether this represents a causal effect or shared aetiology and whether these relationships are body mass index ...
