There is no consensus on the relation between ulnar styloid process nonunion and outcome in patients with distal radius fractures. The aim of this study was to analyze whether patient-reported outcome is influenced by the nonunion of the accompanying ulnar styloid fracture in distal radius fracture patients.
A meta-analysis of published studies comparing outcomes after distal radius fractures with a united versus a non-united ulnar styloid process was performed. In addition, if provided by the authors, the raw data of these studies were pooled and analysed as one study. The outcome measures of the analyses included patient-reported outcome, functional outcome, grip-strength, pain, and distal radioulnar joint (DRUJ) instability.
Data from six comparative studies were included, concerning 365 patients with a distal radius fracture. One hundred and thirty-five patients with an ulnar styloid union were compared with 230 patients with a nonunion of the ulnar styloid. No significant differences were found between groups regarding any outcome measure.
Based on this meta-analysis, there is no relation between the nonunion of the ulnar styloid process and function in patients with a distal radius fracture.
桡骨远端骨折患者中尺骨茎突不愈合与预后的关系尚无定论。本研究旨在分析桡骨远端骨折患者中，伴随的尺骨茎突骨折不愈合是否会影响患者报告的预后。
对已发表的研究进行荟萃分析，比较桡骨远端骨折愈合与尺骨茎突未愈合患者的预后。此外，如果作者提供了这些研究的原始数据，则将其汇总并作为一项研究进行分析。分析的结局指标包括患者报告的预后、功能结局、握力、疼痛和下尺桡关节（DRUJ）不稳定。
纳入了六项比较研究的数据，涉及365例桡骨远端骨折患者。将135例尺骨茎突愈合患者与230例尺骨茎突不愈合患者进行比较。在任何结局指标上，两组之间均未发现显著差异。
基于这项荟萃分析，桡骨远端骨折患者的尺骨茎突不愈合与功能之间没有关系。
