Artem's fractured spine

Strictly Come Dancing's Artem Chigvintsev performed on last weekend's show without realising that he had fractured his spine.

The 29-year-old, whose dance partner is actress Holly Valance, suffered the injury last Friday while rehearsing for the programme.

The injury was initially diagnosed as a strained muscle and it was only yesterday that medical results revealed a fracture of the lumbar spine.
