Abstract: Objective To investigate the characteristics of forensic clinical identification on common peroneal nerve injury in traffic accident. Methods Eight cases of common peroneal nerve injury in traffic accidents were analyzed, including general condition of the wounded, the way of injury, the imaging results, the EMG results, and the degree of injury, etc. Results In 8 cases, 2 cases of complete common peroneal nerve injury were determined to grade 9 （disability degree） and 6 cases of partial common peroneal nerve injury were determined to grade 10 （disability degree）. Conclusion By comparison, the disability degree of complete common peroneal nerve injury is higher than that of partial common peroneal nerve injury. The forensic clinical identification of common peroneal nerve should be made with synthetical consideration of medical history, symptoms, and auxiliary examinations.
