people growing horn-like structures on their skulls due to smartphone use — may in fact have a simple explanation: bone spurs.
The study, which was published last year in the journal, indeed found bony growths on the bases on skulls of around 400 adults, ages 18 to 86. And younger people were found to have larger growths. The researchers referred to these growths as a “prominent exostosis … emanating from the external occipital proturbance.” Or, in layman’s terms, a bone spur, located at the base of the skull. Bone spurs — small bony growths that can form on the edges of bones — occur when inflammation damages the cartilage that cushions joints, and the body tries to repair the damage by growing more bone. They often form from repetitive motions. One type of repetitive motion is tilting the head forward, perhaps to look at a smartphone.
The bone spurs identified in the study ranged in size from 10 to 31 millimeters. Some were so big that they could be felt as a lump on the back of the head. The development of these growths may be attributed to, and explained by, extensive screen-time, the researchers said. Sustained “forward head flexion,” or bending the head down, and poor posture could be the reasons for these physiological changes, they hypothesized. The findings highlight how little is known about the extensive use of these technologies. “Although the ‘tablet revolution’ is fully and effectively entrenched in our daily activities, we must be reminded that these devices are only a decade old and it may be that related symptomatic disorders are only now emerging,”
Most bone spurs don’t cause pain and require no treatment, but they can become a problem if they reach a certain size.
“You’re at the airport or school and everyone is hunched over. It would be fine if it was 15 seconds here or 15 seconds there, but when it’s over hours you’re concerned that this habitual behavior can result in a real curved deformity, especially in kids but really all adults,” researcher said.
The study “isn’t going to convince people not to use their phone. But small changes like putting pillows under our laptops and holding the phone or tablet higher up and away from our laps can promote better posture,” Geier added.
“We need to get up and moving. We have got to get people more active for a number of reasons. The sedentary aspect of this is huge and these devices are killing us in that respect.”
