It was narrated from Ikramah, from Al-Hajja bin Amr that the Prophet said:
Whoever breaks his leg or suffers a leg injury, then he has exited Ihram, but he has to perform another Hajj. I asked Ibn 'Abbas and Abu Hurairah and the said: He spoke the thurth. And in his narration (one of the narrators) shuaib said: He has to perfom Hajj the following year.
