Title: Fracture Recurrence in Hip Fracture with Menopausal Hormone Therapy vs Risedronate: A Clinical Trial

Abstract

Introduction: The efficacy of menopausal hormone therapy (MHT) on secondary fractures and death in postmenopausal women sustaining hip fracture has been sparsely studied. An open-label, randomized trial was conducted to examine the effects of risedronate therapy versus MHT in postmenopausal Korean women.

Materials and Methods: Among 1,165 women aged 55 years or older with acute, lower-trauma hip fracture, 281 were recruited and randomly assigned to receive oral risedronate (35 mg/week) or percutaneous estradiol gel (1.5 mg/day) plus oral micronized progesterone (100 mg/day) for 4 years. The primary end point was recurrent fracture and the secondary end points were mortality and bone mineral density (BMD).

Results: Seventy-four women (risedronate; 45, MHT; 29) completed the trial (33.2%). Kaplan-Meier analyses showed no significant differences in fracture recurrence and mortality between the two groups. The incidence of any new fracture per 100 person-years (PY) was 8.63 in the risedronate group and 12.86 in the MHT group (P=0.180); that of clinical fracture was 4.75 and 6.99, respectively (P=0.265); that of asymptomatic vertebral fracture was 4.87 and 5.58, respectively (P=0.764). The respective incidence of death per 100 PY was 3.58 and 4.40 (P=0.503). BMD increased comparably at lumbar spine in both groups. BMD at total hip did not change in the risedronate group, but increased significantly by 2.8% at 4 years in the MHT group.

Conclusion: MHT using percutaneous estradiol gel and oral micronized progesterone might not differ from risedronate in the prevention of secondary fractures and death among postmenopausal Korean women with recent hip fractures.
