Noel Fitzpatrick deals with one of his toughest cases when Bella the boxer requires surgery, following a road accident a year ago.

Noel hopes to fill a large area of lost bone using new stem cell technology, but this type of procedure has never been done before on this scale.

Meanwhile, four little hedgehogs arrive, each with a broken leg, plus Gizmo the kitten needs his broken leg fixing so he can scurry home to his worried playmate, six-year-old Summer.
