Methods 22 patients with type C distal radial fractures treated by surgical treatment were reviewed. Results The follow-up period of the 22 cases ranged from 6 months to 14 months. By Gartland & Werley scoring, 16 patients achieved excellent results，3 achieved good results and 3 achieved fair. The excellent and good result rate was 86.4%.
