Mark Cahill had the operation on the 27 December and doctors have said he is making "good progress".
- Leeds Teaching Hospitals announced in late 2011 that it was starting to look for potential candidates for hand or arm transplants.
- The UK team has been working closely with colleagues in Lyon, France, where hand transplants were pioneered in 1998.
- A new technique meant Mr Cahill could have his non-functioning right hand removed in operation where a donor hand was also transplanted.
- The first-ever recipient in France was New Zealander Clint Hallam, who later had his new hand removed as he felt "mentally detached" from it.
- Doctors in the United States, Austria and France have carried out a number of successful hand transplants.
Dr Hilary Jones explained on Daybreak how Mark Cahill's hand transplant was a world first.
He said hand transplants have been done since the 1960s, however this is the first time that the hand has been removed and the donor organ has been transplanted on at the same time.
