Fosamax (alendronate sodium) has been prescribed to millions of people in the United States since it was approved in 1995 for treatment of osteoporosis and Pagets disease of the bone.  While most users are given the drug for many years,  studies and adverse event reports suggest that long-term use of the drug may increase the risk of low-energy bone fractures, most commonly involving the thigh bone or femur.

In 2008, researchers published a study in the May/June issue of the Journal of Orthopedic Trauma that found a femur fracture pattern that was 98% specific to users of Fosamax. The study reviewed 70 low-energy femur fractures that were typically caused by falls from a standing height or less. The study was able to identify a specific type of fracture that occurred almost exclusively in women who had been taking Fosamax over a long period of time.

A September 2009 report in the Journal of Bone and Mineral Research highlighted femur fractures suffered by a Fosamax patient suffering from rheumatoid arthritis, who took the drug for eight years. 

The report found that the patient had an imbalance between bone resorption and bone formation at the site of a rare femur fracture known as a spontaneous bilateral subtrochanteric/diaphyseal fracture, suggesting that the broken bones may be connected to the long-term use of Fosamax.

While Fosamax is prescribed to treat osteoporosis and reduce the risk of hip fractures and long bone fractures, the mechanism of action, which prevents bone turn-over, could make some users vulnerable to certain types of fractures. In addition to the low-energy femur fractures associated with Fosamax side effects, users have also reported deterioration of the bone in the jaw, hip, knees and shoulders, which can cause permanently disabling injuries.

Merck already faces hundreds of lawsuits over Fosamax jaw bone problems, which can cause deterioration or decay of the jaw; a condition known as osteonecrosis of the jaw (ONJ). The federal Fosamax ONJ lawsuits have been consolidated and centralized into a multidistrict litigation (MDL) in the U.S. District Court for the Southern District of New York.
