Beth Tweddle has undergone surgery to fuse together two fractured vertebrae in her neck, her family has said.
Olympic gymnast Tweddle suffered the injury during the making of Channel 4 programme The Jump.
Surgeons took a bone fragment from Tweddle's hip and used it, along with pins, to fuse together two fractured vertebrae in her neck.
The former gymnast thanked well-wishers, she said: "Thank you so much for your support and concern. The last 48 hours have been very scary but all the messages have really helped to keep me positive. I will keep you updated on my progress."
Tweddle's parents, Ann and Jerry, said initial medical indications were positive as she can move her hands and feet.
