The bionic mermaid
Rhianna Clavering, 15, was devastated when her spine started to twist so much that she had a 75 degree curve in her back.
Doctors had to take action when it became so severe that it was starting to crush her internally - damaging her lungs.
They carried out an operation to put two metal rods either side of her spine - and then they sprinkled a calcite powder made from sea krill on top to help the bone to harden and fuse.
And amazingly Rhianna woke up from the operation a staggering FOUR INCHES taller than she was before the operation.
