A group of Boston researchers found that women with larger buttocks are less likely to suffer a hip fracture than women who are more slender, reports a publication of the Arthritis Foundation.

According to Arthritis Today, the researchers evaluated a group of older women to determine why some experience more hip fractures than others.All the women had previously suffered falls and all had a similar degree of osteoporosis, yet just over two-thirds had actually fractured a hip because of their falls.

The researchers concluded that the women who didn't break their hips had more fat - more "soft-tissue energy absorption capacity," as they called it - on their buttocks than those who suffered fractures.
