Hip guards may be a cost-effective way to prevent hip fractures in the elderly, according to Canadian researchers who echo previous findings by American investigators.

University of British Columbia researchers assert that the hip protectors prove to be more efficient than the two most common methods of managing osteoporosis in their nursing homes today: using calcium or vitamin D supplements or not treating it at all. Their findings are reported in the August issue of the Journal of Rheumatology.

Hip pads, which are worn like a bulky pair of underwear, are widely used in Europe but not as much in North America, the researchers said, adding that more than $10,000 could be saved for each hip fracture the $150 hip protectors prevent.
