There have been recent reports linking alendronate and a specific pattern of subtrochanteric insufficiency fracture. We performed a retrospective review of all subtrochanteric fractures admitted to our institution between 2001 and 2007. There were 20 patients who met the inclusion criteria, 12 of whom were on long-term alendronate. Alendronate-associated fractures tend to be bilateral (Fisher's...

INTRODUCTION: Bisphosphonates are well known potent inhibitors of osteoclast activity and are widely used in the clinical treatment of osteoporosis and various systemic metabolic bone diseases. Alendronate, a nitrogen-containing bisphosphonate, is a potent inhibitor of bone resorption widely used for the treatment and prevention of osteoporosis. Recently, bisphosphonates have been demonstrated ...

OBJECTIVE To evaluate the effects of the antiresorptive agent alendronate at a daily oral dose of 40 mg in patients with posttraumatic complex regional pain syndrome type I (CRPS I) of the lower extremity. METHODS Forty patients were enrolled in this 8-week randomized, double-blind, placebo-controlled study of alendronate therapy for CRPS I, a condition associated with regional osteoclastic o...

OBJECTIVE To evaluate the efficacy and safety of oral alendronate sodium therapy once daily in preventing glucocorticoid-induced bone loss in patients with immunobullous skin diseases treated with long-term glucocorticoid therapy. DESIGN A 12-month randomized, double-blind, placebo-controlled trial. SETTING A tertiary referral dermatology center in Singapore. PARTICIPANTS Patients newly d...

OBJECTIVES To evaluate and compare the efficacy and safety of the combination of raloxifene and alendronate with those of monotherapies in elderly women with osteoporosis. METHODS Sixty-two postmenopausal women (mean age 63.5 ± 0.5 years) attending gynecologic osteoporosis clinics with established osteoporosis were randomly allocated to one of four treatment groups and monitored for 3 years. ...

Ingestion of alendronate sodium (Fosamax) had been reported to sometimes cause erosive or ulcerative esophagitis. Despite its widespread use and several case reports describing the clinical and endoscopic presentation, there has been limited discussion on the histologic appearances of the esophagitis caused by the medication. Here we describe one case of an elderly woman who presented with alen...

Several recent medical articles have described multiple cases of unusual low-impact subtrochanteric stress fractures or completed fractures of the femur in patients who have been on the bisphosphonate alendronate for several years for osteoporosis or osteopenia. Some patients have experienced such fractures in both femurs. The fractures are often preceded by pain in the affected thigh, may have...

BACKGROUND Particle-induced osteolysis is currently a major problem affecting the long-term survivorship of total joint replacements. Alendronate is a third-generation bisphosphonate that blocks osteoclastic bone resorption. The objective of this study was to determine whether alendronate could prevent particle-induced osteolysis or restore (reverse) bone loss in established osteolysis. METHO...
