Abstract: 〗［Abstract］〓Objective〖HTSS〗〓To investigate the preliminary results of locking plate in the treatment of Diepunch fracture of the distal radius.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Twentyeight patients were enrolled in this study . Surgical duration, intraoperative blood loss, incision length, postoperative hospital stay and the other index were recorded. Visual analogue scale（VAS） score, Disabilites of the Arm, Shoulder,and Hand（DASH） score, Sarmiento Colles score were performed to evaluate clinical results of these patients.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The mean time of surgical duration, intraoperative blood loss, incision length, postoperative hospital stay and DASH score of the 28 Diepunch fracture patients who were treated by locking plate therapy were(64.35±12.16) min， (51.68±891) mL， (8.28±1.36) cm， (6.87±1.47) d， respectively. During a 3month followup, VAS score(0.68±0.72) and DASH score(5.86±7.38) showed excellent wrist function in 22 cases, good wrist function in 4 cases, fair wrist function in 1 case and poor wrist function in 1 case, with an excellent and good rate of 92.86 %.There was no significant difference in scores of functional status among dorsal type, palmar type and longitudinal split type（P＞0.05）.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Locking plate can ensure the biomechanical stability required for Diepunch fractures, and the good function of the wrist can restore after postoperative functional exercise.
