Objective : The purpose of this study is to report the patient with radial nerve injury associated with humerus shaft fracture, who was improved by Korean medical treatments. Methods : The patient was treated by Jungsongouhyul pharmacopuncture, electrical stimulation therapy, physical therapy, and herbal medicine according to "Locating Yang brightness meridians" theory. Coding result, Numeric rating scale(NRS) and digital grip dynamometer were used to evaluate the wrist drop, numbness of fingers and grip power. Results : The patient showed the first sign of recovery after 6 weeks from onset. After 9 weeks from onset, the patient could perform delicate manual activity. Grip power showed noticeable improvement as well as coding result and NRS. Conclusions : The results suggest that providing Korean medical treatments according to "Locating Yang brightness meridians" theory is a good method for treating radial nerve injury associated with humerus shaft fracture. But further studies are required to concretely prove the effectiveness of this method for treating radial nerve injury associated with humerus fracture.
