A 2-month-old Chinese boy was recovering Tuesday after surgery to remove an
unusually well-formed third arm.

they successfully removed a third arm from a 66-day-old infant.
Neither of the boy's two left arms was fully functional, but surgeons decided
to remove the one growing closer to his chest after tests showed it was less
Dr. Chen Bochang, the chief surgeon, said the three-hour operation at
Shanghai Children's Medical Center went much better than expected.
"We found the nerves and blood vessels for the arm were formed just as they
would be for a normal arm," Chen told reporters.
Chen said the baby will require long-term physical therapy to gain function
in his remaining hand, which has no palm and flexes in either direction.
"We're hoping to exchange information with doctors who've dealt with similar
cases anywhere in the world," said Chen, head of the orthopedics department at
Shanghai Children's Medical Center. "This is so rare that we have virtually no
information to go on."
Liu's mother said she was relieved the surgery was over but worried for her

"I'm very happy but there are some fears that I just can't let go," said the
woman, who asked that her name not be used to maintain her privacy. "I worry
about how he will grow, whether this will have a big impact on his growth."
The parents are farmers from rural Anhui province, west of Shanghai.
Chen said doctors don't know what causes such additional limbs, although many
speculate they start out as limbs of a conjoined twin that never developed. He
ruled out environmental factors such as birth defect-causing pollution, saying
that couldn't fully explain similar cases elsewhere.
Chen said no reliable figures exist on the frequency of such cases, partly
because many fetuses with more than four limbs are aborted or miscarried.
In most cases where the fetus survives, it's clear which limb is less
developed and should be amputated. Junjie's case was especially rare because
both left arms were almost equally developed. He said doctors decided to remove
the one closest to the chest because it did not fully extend.
Because of shortfalls in China's rural health system, Liu Junjie's mother
never received an ultrasound before giving birth, Chen said.
