PURPOSE In this study, the removal torques of commercially pure titanium Implants that had been implanted simultaneously with the start of treatment for osteoporosis were compared to those of a group without treatment and a healthy group. MATERIALS AND METHODS Rats treated by ovariectomy or sham surgery at the age of 12 weeks were used. Twenty-eight days after surgery, the rats treated by ova...

with anti-resorptive agents, such as bisphosphonates, offer the potential for synergistic benefits for patients at high risk of fracture. Although fracture endpoint studies exist for monotherapy with either bisphosphonates or PTH, such studies do not exist for treatment strategies involving combined or sequential use of PTH and bisphosphonates, and only studies with surrogate endpoints currentl...

BACKGROUND Orally administered bisphosphonate drugs (i.e., alendronate, etidronate, risedronate) can reduce the risk of vertebral fracture. However, only alendronate and risedronate have proven efficacy in reducing the risk of hip fracture. We sought to examine the comparative effectiveness of orally administered bisphosphonate drugs in reducing hip fractures among older adults. METHODS We id...

The effectiveness of hormone replacement therapy (HRT) and alendronate, alone and in combination, was evaluated in 120 postmenopausal patients with osteoporosis with bone mineral density (BMD) measurements at least 2 SD below the mean value for young premenopausal subjects. They had no contra-indications to HRT or alendronate use and were randomized to three different treatment groups. Group I ...

BACKGROUND Since the use of parathyroid hormone as a treatment for osteoporosis is limited to two years or less, the question of whether antiresorptive therapy should follow parathyroid hormone therapy is important. We previously reported results after the first year of this randomized trial comparing the use of full-length parathyroid hormone (1-84) alone, alendronate alone, or both combined. ...

BACKGROUND Many women using hormone replacement therapy (HRT) will discontinue HRT and lose its bone-protective effect. Methods to preserve bone density in these women need to be explored. This multicenter, international, randomized, blinded, 12-month study was conducted to assess the effect of alendronate sodium on bone density in women who had recently discontinued HRT. METHODS The 144 post...

Osteoporosis, which is a major health problem, may have an adverse impact on the economic status of the society and the quality of the life of the patients. Long-term alendronate use may cause an increased susceptibility to fractures with an increased risk of delayed union. In this article, we describe two patients on long-term alendronate therapy which were treated for atypical femoral fractur...

Retinol is a commonly used vitamin, especially by elderly people. Alendronate sodium, an aminobisphosphonate, is a potent antiresorptive drug used in the treatment of osteoporosis in postmenopausal women. Frequently, alendronate sodium and retinol are used concurrently. There are no reports on the interaction between alendronate sodium and retinol. The aim of the present study was to investigat...

Osteoporosis-related fractures are a major public health problem and one in two women and one in four men are affected with osteoporosis-related fractures. Alendronate (Fosamax) is one of the first bisphosphonates used to treat osteoporosis effectively. Recently, however, there is a concern regarding long bone insufficiency fractures related to long-term alendronate therapy. We report a case of...

CONTEXT Alendronate sodium reduces fracture risk in postmenopausal women who have vertebral fractures, but its effects on fracture risk have not been studied for women without vertebral fractures. OBJECTIVE To test the hypothesis that 4 years of alendronate would decrease the risk of clinical and vertebral fractures in women who have low bone mineral density (BMD) but no vertebral fractures. ...
