Abstract Background Hip fracture is associated with pronounced morbidity and excess mortality in elderly women with postmenopausal osteoporosis. Many drugs have been developed to treat osteoporosis and to reduce the risk of osteoporotic fractures. We investigated the effects of combined alendronate and vitamin D3 treatment on bone mass and fracture load at the femoral neck in ovariectomized OVX rats and evaluated the relationship between bone mass parameters and femoral neck strength. Methods Thirty 12-week-old female rats underwent either a sham-operation n 6 or OVX n 24 . Twenty weeks later OVX rats were further divided into four groups and received daily doses of either saline alone mg kg alendronate pg
