Greater understanding of specific fracture patterns following distal radius fractures has arisen with the advent of volar plating. The volar marginal fragment (VMF) is a small peripheral piece of bone which is critical to carpal stability. Failure to achieve good fixation of the VMF can result in volar subluxation of the carpus and distal radioulnar joint instability. Due to its small, distal nature, this fragment can be easily missed and difficult to fix. Loss of reduction of the VMF following operative fixation presents specific challenges and surgical considerations dictated by patient characteristics and timing. Our goal of this review is to present a classification system for these failed VMFs which can help guide surgical treatment as well as expected outcomes.
随着掌侧钢板的出现，人们对桡骨远端骨折后的特定骨折模式有了更深入的了解。掌侧边缘碎片（VMF）是一小块对腕骨稳定性至关重要的周边骨质。未能实现对VMF的良好固定可能会导致腕骨掌侧半脱位和远端桡尺关节不稳定。由于其体积小且位于远端，该碎片很容易被遗漏且难以固定。手术固定后VMF复位丢失带来了特定的挑战以及由患者特征和时机决定的手术考量。本综述的目的是提出一种针对这些失败的VMF的分类系统，该系统有助于指导手术治疗以及预期结果。
