Distal ulna fractures, especially styloid injuries, classically have not been repaired, and only recently have these injuries been considered important. Certain fracture patterns of the distal ulna contribute to distal radioulnar joint (DRUJ) incongruity and potential instability. Appropriate fixation of the distal ulna is frequently difficult for several reasons: (1) high incidence of osteoporois in the affected patient population, (2) proximity of the injury to articular surfaces, and (3) lack of a proper implant to treat these injuries. The 2.0-mm locking compression distal ulna plate (LC-DUP) is an anatomically contoured implant with a low profile and fixed angle that provides proper stability to treat injuries of the distal ulna. The plate was designed for the treatment of distal ulna fractures, but its success has led to an extension of its indications to be used in treating symptomatic basistyloid ulnar nonunions and in ulnar shortening osteotomy for ulnocarpal abutment syndrome. The authors' description of the techniques used for each indication as well as their perspectives in the treatment of distal ulna injuries are described in detail in this report.
尺骨远端骨折，尤其是茎突损伤，传统上并不进行修复，直到最近这些损伤才被视为重要情况。尺骨远端的某些骨折类型会导致下尺桡关节（DRUJ）不匹配和潜在不稳定。由于多种原因，对尺骨远端进行适当固定常常很困难：（1）受影响患者群体中骨质疏松症的高发病率，（2）损伤靠近关节面，以及（3）缺乏合适的植入物来治疗这些损伤。2.0毫米锁定加压尺骨远端钢板（LC - DUP）是一种外形符合解剖结构、低轮廓且角度固定的植入物，可为治疗尺骨远端损伤提供适当的稳定性。该钢板设计用于治疗尺骨远端骨折，但其成功促使其适应证扩展至用于治疗有症状的尺骨茎突基底部不愈合以及用于尺腕撞击综合征的尺骨缩短截骨术。作者在本报告中详细描述了用于每种适应证的技术以及他们对尺骨远端损伤治疗的观点。
