Several types of fixation materials may be used for the radial styloid fractures such as Kirschner wire fixation, screw fixation, volar plate fixation, and fragment-specific radial buttress plate fixation. However, each of these fixation techniques has certain complications usually related to either the surgical dissection or the application of fixation and symptomatic permanent hardware. Implant removal secondary to irritation of prominent screw heads or bulky plates is not uncommon after radial styloid fracture fixation. Herein, two patients with an isolated radial styloid fracture who were treated with bioabsorbable magnesium (alloy: MgYREZr) screws are presented. In both patients, the fracture union was achieved without any complication and need for implant removal. This is the first report on the use of magnesium screws for this indication. Magnesium bioabsorbable compression screw fixation may be an alternative solution that eliminates removal operations due to symptomatic hardware in radial styloid fractures.
桡骨茎突骨折可使用多种固定材料，如克氏针固定、螺钉固定、掌侧钢板固定和碎骨块特异性桡骨支撑钢板固定。然而，这些固定技术中的每一种都有某些并发症，通常与手术解剖或固定应用以及有症状的永久性内固定物有关。桡骨茎突骨折固定后，因突出的螺钉头或厚重钢板刺激而进行内固定物取出的情况并不少见。本文介绍了两名孤立性桡骨茎突骨折患者，他们接受了生物可吸收镁（合金：MgYREZr）螺钉治疗。两名患者均实现了骨折愈合，且无任何并发症，也无需取出内固定物。这是关于将镁螺钉用于该适应症的首次报告。镁生物可吸收加压螺钉固定可能是一种替代解决方案，可消除因桡骨茎突骨折中有症状的内固定物而进行的取出手术。
