CHEN's criteria for postoperative functional evaluation of severed limbs replantation / 中华显微外科杂志

ABSTRACT

As continuous progressive improvement in microsurgery, the postoperative evaluation of severed limbs replantation has been developed from the survival to the functional recovery of replanted extremity. In 1978, Chen Zhongwei devised a system for the function evaluation of the 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 the purpose to offer a reference in the standardization and promotion of a practical standard for the postoperative functional evaluation of severed limb replantation.
