The coronoid process of the ulna is the primary stabilizer of the elbow joint. There has not yet been an accurate off-the-shelf dedicated implant because fragments of coronoid process fractures are often small and diverse. The variable angle locking compression mesh plate 2.4/2.7 (Depuy Synthes, West Chester, PA, USA) acts as a versatile, low-profile implant that can be cut to suit the specific fracture pattern and fits anatomically.
We report two cases of Regan-Morrey type II ulnar coronoid process fractures in terrible triad elbow injuries. In both cases, persistent instability was fluoroscopically diagnosed after repair of the lateral structures. We performed osteosynthesis for the ulnar coronoid process fractures using a mesh plate, which we cut into a rhombus-like shape and used as a buttress plate. Here we report the good results obtained thereof.
Considering our positive experience with using mesh plates, the mesh plate may be a good method of fixation for ulnar coronoid process fractures.
尺骨冠突是肘关节的主要稳定结构。由于冠突骨折碎片通常较小且形态各异，目前尚无精确的现成专用植入物。2.4/2.7可变角度锁定加压网板（美国宾夕法尼亚州韦斯特切斯特市迪普伊辛迪斯公司）是一种通用的、低轮廓植入物，可进行切割以适应特定骨折模式并符合解剖结构。
我们报告两例可怕三联征肘关节损伤中雷根-莫雷II型尺骨冠突骨折的病例。两例患者在修复外侧结构后经透视诊断均存在持续不稳定。我们使用网板对尺骨冠突骨折进行了骨固定，将网板切割成菱形用作支撑钢板。在此我们报告由此获得的良好结果。
鉴于我们使用网板的积极经验，网板可能是治疗尺骨冠突骨折的一种良好固定方法。
