Abstract
As continuous progressive improvement in microsurgery, postoperative evaluation of severed limbs replantation has been developed from survival to functional recovery of replanted extremity. In 1978, Chen Zhongwei devised a system for function evaluation of replants, considering the ability to work, range of motion, recovering of sensation, and recovering of muscle power. This system was called CHEN’s criteria and it is still internationally used. In recent years, new parameters and measuring methods have been created without an agreed international standard. This article serves purpose to offer a reference in standardization and promotion of a practical standard for postoperative functional evaluation of severed limb replantation. Key words: Severed limb replantation; Upper extremity replantation; Function evaluation; CHEN's criteria; Standard for evaluation
