The princess told ITV in an interview prior to the wedding: "I think you can change the way beauty is, and you can show people your scars and I think it's really special to stand up for that."
Eugenie, a patron of the Royal National Orthopaedic Hospital, also reportedly invited her surgeon and other medical staff to the wedding, Vanity Fair reported, as a way to honor them. The surgery, which Eugenie said took eight hours, required the placement of titanium rods on each side of her spine. She spent three days in intensive care and another couple of weeks recovering during which she used a wheelchair, but after that, she was walking again, according to the hospital's website.
Scoliosis is a sideways curvature of the spine that occurs most often during the growth spurt just before puberty, according to the Mayo Clinic. While most cases are mild, some, like in Eugenie's case, require corrective surgery.
Eugenie, 28, married tequila brand ambassador Jack Brooksbank, 32, Friday at St. George's Chapel at Windsor Castle, with many royal family members in attendance.
