The world's first double hand transplant surgery has been a success as the 10 year old child who received it, is now able to write, dress and even play baseball. <br/><br/>Zion Harvey of the US was two-years-old when he had sepsis, a life-threatening infection. Doctors had to remove both his hands at the wrist, and his legs below the knee. He was given new hands when he was eight-years-old. <br/><br/>A member of the team treating Harvey at the Children's Hospital of Philadelphia, said the fact that he is able to swing a bat with much more co-ordination, and write his name quite clearly, is an evidence that his brain had rewired to take account of his new hands.<br/><br/>Double hand transplantation is a complex procedure involving many surgical and non-surgical components. <br/><br/>Although the first ever double-hand transplant was done in 1998, Harvey became the youngest to ever undergo the procedure.
