"Dancing with the Stars" pro Derek Hough is proud of his "miracle wife." Hough opened up to Fox News Digital about Hayley Erbert's emergency skull surgery in December and the miraculous recovery that has led her back to the dance studio. Hough explained that the medical professionals who aided Erbert were looking for more severe, permanent damage after her emergency craniectomy and her cranioplasty a few weeks later, but they couldn't find anything. "It's nothing short of a miracle, honestly," he said.
