Abstract：Objective To compare the differences of therapeutic effects of open reduction and internal fixation in treatment of distal radius C-type fractures through the modified Henry approach versus the dorsal approach, and to explore the application value of modified Henry approach. Methods A total of 100 patients with C-type fractures of distal radius treated in Denfeng People's Hospital from January 2014 to June 2016, were randomly divided into the observation group (via modified Henry approach) and the control group (via the dorsal approach). Between these two groups, Cooney's wrist function scores were compared; Disabilities of arm, shoulder & hand (DASH) scores, as well as volar tilt angle and ulnar inclination angle were measured before and after the surgery;At the same time, the complications were also recorded. Results At one month postoperatively, the excellent and good rate of Cooney's wrist function scoring in observation group was superior than that in control group (92% vs 74%, P <0.05). The postoperative DASH scores in two groups were all improved compared to preoperative one (P <0.05), and the improvement in observation group was better than that in control group (P <0.05). All patients were followed up for 3-22 months (average, 6 months). The difference of the rate of complications had statistical significance between the observation and the control groups during the follow-up (4% vs 20%, P <0.05). Conclusion Compared to the dorsal approach, the modified Henry approach could improve the function of the wrist, decrease the volar tilt angle and ulnar inclination angle of the radius, and reduce the risk of postoperative complications for patients with C-type fracture of distal radius.
