After cutting the bones, surgeons used rods to reconnect the bones in the proper shape.

The 3-D skeleton model was produced by Shenzhen Sunshine Laser and Electronics Technology, a company specializing in 3-D printing.

Bai Song, general manager of the 3-D printing department at the company, said the model was made of photosensitive resin and cost around 2,000 yuan ($310).

"Right now, 3-D printing technology is new and unfamiliar to many hospitals and doctors in the country. Application of the technology has been small," Bai said.

Bai said he believes the technology will have a wide application in medical treatment, but admitted that there are difficulties to be overcome.

"First, most doctors have little knowledge about the emerging technology. There has been little demand from hospitals. Second, the cost of 3-D printing is also an issue that needs to be taken into consideration," Bai said, adding that his company's German 3-D printing equipment cost 4 million yuan.

The boy, from Guiyang, Guizhou province, who underwent the operation on June 24, is now recovering and will still receive periodical medical examinations.

"My son had fractures every two or three days. He had to walk very carefully to avoid the situation," said the boy's father, surnamed Lu. "I am so happy and grateful that he can now stand up."

Brittle bone disease is a rare congenital disease that makes it extremely easy for patients to have fractures. One in 10,000 to 15,000 people suffers from the illness.
