Haitians who were badly hurt in an earthquake that rocked the capital Port-Au-Prince will be faced with a shortage of replacement limbs after the country's only prosthetic clinic was heavily damaged, says an Ottawa doctor.

The Haitian government estimates more than 250,000 people were injured in the magnitude 7.0 earthquake that struck there 12 days ago. Many of those hurt have lost limbs after being crushed or trapped in collapsed buildings.

But those who need prosthetic limbs will find that help will be slow to come because of the heavy damage to a specialized clinic in the capital.

The Kay Kapab clinic, set up 10 years ago by the group Healing Hands for Haiti International, manufactures replacement limbs and teaches Haitians how to make them.

More than three-quarters of the clinic and its contents has been severely damaged in the quake, said Scott Weibe, an Ottawa doctor who volunteers for the Healing Hands group.

"So we don't even know, at this point, if and when prosthetic services will be available again," he told CBC News. "Trying to serve many hundreds of new amputees in the coming weeks, months and years will be a very difficult situation."

All the native Haitian staff at the clinic survived the quake, said Weibe.

They're meeting with other volunteers this week to assist in acute care and also assess what needs to be done to resurrect the clinic. But Weibe acknowledged that getting the clinic up and running might not be the most pressing issue for many of the staff members.

"We have heard fortunately that many of the staff from Healing Hands who are native Haitians have survived, albeit with losses of family and losses of home," he said.

"So it remains to be seen whether Haitians who have some skill with prosthetic manufacturing, whether or not their first priority is going to be getting back to work."

About two million Haitians were left homeless by the quake, officials estimate. It is also believed that 250,000 are in need of urgent aid. While the death toll is estimated at 200,000, some say an exact tally will never be known.
