Cell phones may weaken bones

A study suggests that cell phone users might be at heightened risk for a weakening of bone in the hip area.

A small study out of Argentina suggests that cell phone users might be at heightened risk for a weakening of bone in the hip area.

Researchers measured bone mineral content and bone mineral density in the left and right hips of 24 men who carried their cell phones in a belt pouch on their right hip for at least one year and 24 men who did not use cell phones. Mineral content and density are standard markers of bone strength.

The two groups of men had similar average hip bone mineral content/density measurements, but the men who carried cell phones on their right hip had lower mineral content in the right femoral neck, the area near the top of the thigh bone, the team reported.

Cell phone users also had reduced mineral content and density at the right trochanter, an area at the outside top of the thigh bone. Among cell phone users, the difference between the right and left trochanter was significantly associated with the total estimated hours carrying a cell phone on the right hip, said the researchers.

The findings appear in the Journal of Craniofacial Surgery.

Long-term exposure may weaken bones

"The different patterns of right-left asymmetry in femoral bone material found in mobile cell phone users and nonusers are consistent with a non-thermal effect of electromagnetic radio-frequency waves not previously described," wrote study author Dr Fernando D. Sravi, of the National University of Cuyo, Mendoza, Argentina.

He said the findings suggest that long-term exposure to electromagnetic radiation from cell phones could weaken bones. However, Sravi also cautioned that larger follow-up studies are needed to confirm or disprove this hypothesis, and at this point the findings cannot prove any cause-and-effect relationship.

One expert agreed that cell phone users shouldn't read too much into this preliminary research.

"Interesting study, however, it needs to be validated by future studies using larger patient populations," said Dr Victor Khabie, co-chief of the Orthopedics and Spine Institute at Northern Westchester Hospital in NY. "This study does not explain the mechanisms by which a cell phone causes decreased hip mineralization.

Khabie also noted another puzzling aspect of the findings. "Most people who wear a cell phone with a belt actually place it over the iliac crest (high on the pelvic bone). This is, anatomically, a distinct area," He said. "One would think that if the cell phone caused bone loss it would effect the iliac crest rather than the hip, as the phone is actually not worn on the hip."

Sravi said that future, larger studies should clarify things. These studies may be especially important for women, who have higher rates of osteoporosis than men, and children, who will have longer lifetime exposure to cell phones, Sravi added.
