FDA guidelines recommend the sheep as large animal model for osteoporosis. Studies of osteoporosis induction use dual energy x-ray absorptiometry (DEXA) to evaluate bone status. Experimentally, the T-score is calculated based on reference bone mineral density (BMD) values of animals before treatment (0 M). Whereas clinically the reference BMD represents values of an independent group of patients around 30 years old. The study hypothesize that the use of additional ind...

Due to its huge socio-economic impact a better understating of osteoporotic fracture healing is crucial.Thirty-one female merino land sheep were randomly divided into four groups. (i) Untreated control-group (C, n=8); (ii) bilateral ovariectomy (OVX, n=7); (iii) OVX and calcium-deficient diet (OVXD, n=8); and (iv) OVXD and additional biweekly corticosteroid injections (OVXDS, n=8). Drill-hole defects (7.5 mm in diamete...
