"This is not a local phenomenon," said lead author William Shiels II, a radiologist at Nationwide Children's Hospital in Columbus, Ohio.
Since the disorder was identified two months ago, at least six other hospitals have reported similar cases, Shiels said, and a national registry is being set up to monitor the cases.
Self-embedding disorder was defined as using objects to puncture the skin or inserting them into a wound after cutting.
"Our children have progressed to the point where cutting doesn't work," he said.

A 17-year-old girl had embedded 11 objects, including two unfolded paperclips about 6 inches long that were inserted into each bicep, said Shiels, chairman of the department of radiology at the hospital.
"Every time she flexed her muscle, she would feel a twinge of pain," Shiels said.
Another patient came back to the hospital 10 days ago, this time with four more objects that she had embedded, he said.
Parents and even emergency room doctors often are unaware of the injuries, he said.
Often the girls will lie and say the objects got embedded when they fell down.
Using ultrasound or fluoroscopy, a type of X-ray that provides moving images, doctors were able to detect both metallic and non-metallic objects, which then could be removed by through small incisions in the skin.
The approach left little scarring and did not cause the objects to fragment.
Ultrasound proved especially useful because it could detect non-metal objects that did not show up on X-ray, Shiels said.
Sharing on Internet
In recent years, hundreds of messages boards, blogs and other Internet sites have sprouted up, allowing adolescents to solicit and share information about self-injury, sometimes glorifying it.
Most of the sites are used by girls between the ages of 12 and 20, according to a study in Developmental Psychology.
Shiels said he is concerned that children will use the Internet to coach other kids on self-embedding.
Because of that, he said, it is important that doctors recognize the problem.
"This is the most severe form of self-injury," he said.
While none of the self-embedding episodes was part of a suicide attempt, about 90% of the girls had suicidal thoughts, he said.
