"Our study shows that hand transplant surgery is possible when carefully managed and supported by a team of surgeons, transplant specialists, occupational therapists, rehabilitation teams, social workers and psychologists," said Dr Sandra Amaral, of the Children's Hospital of Philadelphia.
费城儿童医院的桑德拉·阿马拉尔医生说：“我们的研究表明，在外科医生、移植专科医生、职业治疗师、康复团队、社会工作者和心理学家团队的细心管理和支持下，手部的移植手术是可以完成的。”
"18 months after the surgery, the child is more independent and able to complete day-to-day activities.

研究人员说，由于术后需使用免疫抑制药物，而该类药物的使用又会有产生其他状况的风险，所以人们在评估此类手术带来的好处和伤害时必须谨慎。
"While functional outcomes are positive and the boy is benefiting from his transplant, this surgery has been very demanding for this child and his family," Dr Amaral said.
阿马拉尔医生说，“尽管移植双手的功能预后良好，哈维也从中受益，然而哈维和家人也为手术付出了很多。”

去年七月，在利兹总医院的一次开拓性手术中，克里斯·金成为了英国接受双手移植的第一人。
