RT Journal Article SR Electronic T1 The HIP trial JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 964 OP 976 VO 69 IS 12 A1 Deal, Chad L. YR 2002 UL http://www.ccjm.org/content/69/12/964.abstract AB The Hip Intervention Program (HIP) trial establishes that risedronate (Actonel) prevents hip fracture in elderly women with osteoporosis. However, the drug had no statistically significant effect on hip fracture risk in elderly women in whom bone density status was not known. Patients should be selected for bisphosphonate therapy on the basis of low bone density. A history of vertebral fractures increases the risk for hip fractures.
