Quadruple Amputee Vet Gets Double Arm Transplant. CBS News. January 29, 2013.
The Johns Hopkins doctors who performed the surgery called it the most complex and extensive transplant so far performed in the United States. The article contains an anatomical diagram of an arm transplant showing the complexity of the procedure. The difficulty is compounded by the possibility of rejection. To deal with this, the vet received bone marrow from the deceased donor in order to prevent rejection. Still he will not be able to move the arm immediately This is because the nerves in the attached arm will grow about an inch a month. As a result it will take over a year for most normal movement in the arm.
