Hip and forearm fractures are the two clinically most important non-vertebral fractures. Twin studies have demonstrated a high heritability of these fractures and the heritable component of fracture risk is largely independent of BMD.To identify common genetic variants associated with hip and forearm fractures, we performed a genome-wide association study (GWAS ~ 2.5 million SNPs) meta-analysis of two large fracture data sets within the well-characterize...

Objectives: Children with Perthes disease may present with altered walking patterns even at the healed stage of the disease. The aim of the study was to assess the walking endurance, fatiguability and gait changes of children with healed Perthes disease, and to determine if walking endurance is associated with hip function and quality of life.Methods: Fifty-one children (38 males) aged 8–16 years with >3 years post-diagnosis of Perthes disease c...

Estrogen deficiency promotes bone loss and skeletal muscle dysfunction. Peroxisome proliferator-activated receptor (PPAR) agonists and high-impact exercise both affect musculoskeletal properties. Whereas PPARδ agonists ameliorate training response in muscle, PPARα agonists exert beneficial effects in bone and muscle. In the present study we investigated the effects of the PPARα agonist fenofibrate and high-impact jumping exercise alone and combined in ovariectom...

Atypical femur fractures (AFF) have been associated with antiresorptive therapy. In a retrospective case-control study, we identified AFF using ASBMR 2013 criteria. Femoral shaft fractures were identified using ICD9 codes. We screened 1479 radiographs. Radiographs were excluded for high-energy trauma, tumor, or periprosthetic fracture. Two radiologists blinded to treatment scored 482 radiographs for AFF features, and jointly adjudicated discrepancies. The required AFF feature,...
