Press your fingers into the back of your skull, just above your neck. If you feel a small spike you may be among people whose body has responded to smartphone use by growing new layers of bone.

The phenomenon involves what is known as an external occipital protuberance:  a growth which appears on the back of the head. David Shahar, a health scientist at the University of The Sunshine Coast, Australia, told BBC.com that in the last decade of his 20 year career he has noticed more patients have the protrusion which was once considered rare.

Shahar explained to BBC.com that when the external occipital protuberance was first studied by French scientist Paul Broca in 1885 "he didn't like it because he had studied so many specimens, and he hadn't really seen any which had it."

In a study published in the Journal of Anatomy in 2016, Shahar and his co-author described how he had been spotting external occipital protuberances more often in x-rays of relatively young patients at his clinic. To find out more, he looked at 218 radiographs of the lateral cervical spine, where the external occipital protuberance appears, of people aged between 18 to 30-years-old. A growth had to be at least 5mm-long to be counted as an external occipital protuberance, with anything bigger than 10mm classifed as enlarged.

It was more common in men than women, at 67 percent versus 20 percent. The longest was 35.7mm in a man, and 25.5mm in a woman.

How much does the human skull weigh? What did doctors call the strain caused by bending the neck too long? What did doctors advise changing if their neck becomes sore? 2. ARTICLE QUESTIONS: Look back at the article and write down some questions you would like to ask the class about the text.

In their research, Shahar and Sayers said young people may be developing tiny hornlike spikes at the back of their skulls , possibly caused by the shift The researchers hypothesize that it is due to poor posture from people craning their heads forward more because of phone and mobile device usage.

This build-up of bone on the external occipital protuberance is a type of enthesophytes.The bony projection on a tendon or ligament is thought to grow gradually over time, so is not expected in young people. Enthesophytes are relatively common in older people.

The study explained that cases of enthesophytes poking out of the external occipital protuberance are rare in the medical literature. A study in 2012, for instance, look at 40 skulls and found just one measuring 9mm.

Shahar and his co-author wrote that their findings could be explained by the rise in the use of hand‐held technologies from early childhood, and said ways to prevent and treat the growths should be considered.

Describing the phenomenon dubbed "text neck," Shahar told BBC.com that as we look down at devices like smartphones and tablets, our necks must work to keep our heads in place. Prolonged straining could lead the body to build new bone to increase the surface area holding up this mass.

In another study published in the journal Scientific Reports in 2018 involving 1200 participants aged between 18 to 86, Shahar's found older people were less likely to have an external occipital protuberance than younger individuals.

Shahar told BBC.com he expects external occipital protuberances to become larger: "Imagine if you have stalactites and stalagmites, if no one is bothering them, they will just keep growing."

Twins conjoined by skulls separated after 50 hours of operations.
Two-year-old twins who were joined by their skulls and blood vessels have been successfully separated after having three major operations at a London hospital. The surgery on Safa and Marwa Ullah, from Charsadda in Pakistan, took place at Great Ormond Street in what has been described as a "long and complex journey". There were also several smaller procedures and experts carried out a total of more than 50 hours of operations involving 100 staff.
