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.
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, local media reports said. 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.
