Treatment of Acute Scaphoid Fractures: A Systematic Review and Meta-Analysis

Abstract

Background/Methods The purpose of this review was to assess the current evidence supporting operative fixation versus casting for acute scaphoid fractures through a systematic review and meta-analysis of the literature. Results Our search yielded 59 articles that met our inclusion criteria with five studies achieving high, 22 moderate, and 32 low Structured Effectiveness Quality Evaluation Scale scores. Pooled results of the four Sackett level 1 evidence studies showed no significant difference between the operative (114/115, 99%) versus non-operative group (106/112, 95%) ( p=0.07) when the definition of nonunion was based on more definitive criterion versus plain radiographs that may be insufficient to assess bony union. Similar results were found for the Sackett level 2 and 4 articles. Conclusions This systematic review reveals that significant weaknesses exist in the literature with respect to the level of evidence and quality of published studies on this topic. Currently, there is insufficient evidence to support the most effective treatment for acute scaphoid fractures.
