The operation was performed to improve the condition of her spine. Princess Eugenie reopened those memories when visiting the Royal National Orthopedic Hospital in London, where she underwent the scoliosis operation. The doctor who treated Princess Eugenie initially estimated that the operation would only take one hour to straighten the curved spine.

However, after starting the operation, they found that the condition of his spine was much worse than anticipated. Quoted from Hudsonvalleyscoliosis, the surgery that was supposed to only take one hour turned into seven hours under the supervision of the anesthesia team.

The following is the translation of the given 'Bahasa' text to 'English' while preserving any html tags: "The surgeons had to insert an eight-inch titanium rod on both sides of Princess Eugenie's spine and a one-and-a-half-inch screw at the top of her neck. This operation required her to be in the intensive care unit for three days, followed by six days in a wheelchair. Eugenie was unable to return to school for several weeks and had to receive lessons from a tutor at home."

In addition, Princess Eugenie also shared an important message on her Instagram account in commemoration of International Scoliosis Awareness Day. In her caption, she wrote, "Today is International Scoliosis Awareness Day. I want to share my scar and encourage anyone who has gone through a similar experience to share their scars with me," Princess Eugenie wrote on her Instagram @princesseugenie.
