. >> reporter: and then there are extraordinary patients like george exantus. exantus was a prize-winning competitive dancer before january 12th, when he was pinned under rubble for days. he lost his leg below the knee and suffered nerve damage in his hand. >> we replaced the prosthetic foot for him, so it was a little more flexible and so he would be able to dance. >> reporter: so he still is? >> oh, yeah, you should put on some music and dance with him. >> reporter: if you just happened on the dance studio where he used to teach and train, you can find him practicing again, but you'd have to look twice, to see his artificial leg. >> this is a temporary leg, given to me so that i can practice, and continue my therapy sessions at home, but they have promised me a better leg, and i'm hoping at some point that will come true. but to dance, you need an extremely expensive leg, but that's not available in haiti, i'll probably never get that. >> reporter: for now, exantus sees his visits to the dance studio just as therapeutic as any doctor's office. >> ( translated
