Derek Hough says wife Hayley Erbert underwent successful skull implant surgery

Derek Hough, left, says his wife Hayley Erbert underwent a cranioplasty, in which surgeons installed a skull implant following a brain bleed. Hayley Erbert’s surgery to replace part of her skull was a success, her husband Derek Hough said. “With immense relief, gratitude and overwhelming joy I’d like to share that Hayley’s cranioplasty surgery has been successfully completed as planned,” the “Dancing With the Stars” judge said in a Thursday Instagram post, which included a photo of him bending down to stare at Erbert from the rail of her hospital bed. Last weekend, Hough said a follow-up surgery was required to install a skull implant to “restore the skull to its natural shape and protect the brain from injury.” Since the initial surgery, Erbert was missing a piece of her skull and had been wearing a helmet.
