SAN FRANCISCO -- Kamani Hubbard was born with 12 functional toes and fingers, but doctors at the University of California San Francisco Medical Center recently removed some of the extra digits, KTVU in San Francisco reported.

Only a handful of people on the planet have the condition, the station said.

“Same processes that a 10-finger person would have -- bone structure and everything -- is perfect with his,” said his mother Miryoki Gross. “His case is very rare.”

The 9-month-old may be one in a billion. Only six other humans known have so-called perfect polydactyly. The station first reported on Kamani’s unique condition in late January, only a few weeks after he was born.

Kamani’s father, Kris Hubbard, noticed his son’s extra fingers and toes the day he was born. Polydactyly is a general trait that runs in his family.

"Some family member have had six fingers, not completely developed. But not the toes," said the 34-year-old Hubbard back in January.

In fact, Hubbard himself had nubs of sixth fingers removed as a child, as these non-functional digits routinely are.

Kamani's family invited KTVU along as they brought the boy in for an operation recommended by his doctors.

“Just talking to them I feel very comfortable that everything is going to turn out OK,” said Hubbard.

Microsurgeon Scott Hansen said he'll leave those perfect six fingers, but not Kamani's extra toes.

Doctors said Kamani's toes are not so perfectly formed as his fingers and the surgery is designed to give him a chance at a life without any foot problems.

“I think as he grows, he'll have difficulty with normal things, running and activities, in his shoes,” said Hansen. “I think that'll be an irritating factor for him."

Because of a special technique, the surgery is completely bloodless. Surgery students came to see this rare case.

X-rays of Kamani's feet show the fifth and sixth metatarsals partly fused.

[There’s] really kind of one bone that hasn't really separated down here yet,” explained Dr. Hansen.

These [are] perfectly formed bones,” said Dr. Hansen. “Six cases, I think, in the world have been reported and I understand why, because at any stage in development something can go wrong and the finger wouldn't function normally.”

It only took minutes for Hansen to remove Kamani's extra toes. Still-growing bones may need trimming a few years from now.

“After two weeks, he'll do just fine,” said Dr. Hansen. “He'll get back to his normal life and not miss the toes.”

But Kamani’s 12 perfect fingers remain intact.

“Hopefully he's able to realize what he has and utilize his abilities and become special,” said Kamani’s proud father.

Kris Hubbard is a postal worker, while mother Miryoki is a full-time mom. Their church has set up a fund to help with medical expenses. As he heals from the surgery, Kamani has weekly doctor visits.

The boy’s mother explained that the fund was intended “to cover things like that after surgery, because he'll be seeing specialists for a long time.”
