Someone I studied bread making with had a similar experience. During and ice-storm, he fell while taking the garbage out and broke his wrist. He had to quit the course. Since he was already a trained cook, and was working as one and starting his own catering business, it must have been a blow to him! But, a only a couple of months later, there he was making excellent breads at home, and posting pictures of it on social media. Breadmaking is hard on the wrists, but he didn't give up. Best of luck to your niece, and a speedy recovery!
