On Tuesday, medical professionals in Shanghai were evaluating potential surgical interventions for a two-month-old 𝑏𝑎𝑏𝑦 boy who was 𝐛𝐨𝐫𝐧 with a remarkably developed third arm. A doctor examined the infant, who is 59 days old, at a hospital in Shanghai on Monday, May 29, 2006. The medical team is assessing the 𝑏𝑎𝑏𝑦’s overall physical health before making a decision regarding the removal of his extra arm. Neither of the boy’s two left arms is fully functional and tests have so far been unable to determine which was more developed, said Dr. Chen Bochang, head of the orthopedics department at Shanghai Children’s Medical Center.

“His case is quite peculiar. We have no record of any 𝘤𝘩𝘪𝘭𝘥 with such a complete third arm,” Chen said in a telephone interview. “It’s quite difficult to decide how to do the operation on him.”

The boy, identified only as “Jie-jie,” also was 𝐛𝐨𝐫𝐧 with just one kidney and may have problems that could lead to curvature of the spine, according to local media reports.

Jie-jie cried when either of his left arms was touched, but smiled and responded normally to other stimuli, the reports said.

Chen said doctors hoped to work out a plan for surgery, but the boy’s small size made it impossible to perform certain tests that would help them prepare.

“We are meeting with several experts now. We hope we could work the plan out soon,” Chen said.

Media reports said other 𝘤𝘩𝘪𝘭𝘥ren have been reported 𝐛𝐨𝐫𝐧 with additional arms and legs, but in all those cases it was clear what limb was more developed.

Chen’s hospital is one of China’s most experienced in dealing with unusual 𝐛𝐢𝐫𝐭𝐡 defects, including separating conjoined twins. Like Jie-jie, many of the 𝘤𝘩𝘪𝘭𝘥ren are sent to relatively wealthy Shanghai from the poor inland province of Anhui.
