There have been over 40 descriptions of the common developmental variants of the accessory ossicles of the feet. Although predominantly asymptomatic, they sometimes may be linked to painful conditions. One of the most common accessory ossicles in the foot is the accessory navicular bone (AN), located on the medial side of the foot. Our research provides a first meta-analysis on this topic that establishes its frequency by contrasting 39 studies from across the globe.
Up to February 2024, PubMed and Embase databases were thoroughly searched for research on the AN. Eligible data regarding AN prevalence was extracted. This study strictly adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
A total of 39 studies, 11,015 patients, and 36,837 feet were analyzed in our study. The pooled prevalence estimate (PPE) of AN was found to be 17.5% (95%CI: 11.5-25.7) and 12.6% (95%CI: 10.1-15.5) in patients and feet analyses, respectively. Accessory navicular occurred bilaterally in 50.0% of patients, with similar distribution in gender-based groups (21.1% of males and 22.0% of females were confirmed with AN). Accessory navicular was most prevalent in the East Asian population (38.4%) and least prevalent in North Americans (8.0%). No significant differences in AN prevalence were found when comparing different imaging modalities (X-ray and cadaver dissection).
Accessory navicular is a common finding in imaging studies. Its prevalence depends on the population covered by the study but is not affected by the patient's gender or the imaging modality utilized for AN assessment.
关于足部副骨常见发育变异的描述已超过40种。尽管大多数情况下无症状，但它们有时可能与疼痛状况相关。足部最常见的副骨之一是副舟骨（AN），位于足内侧。我们的研究首次对该主题进行了荟萃分析，通过对比全球39项研究确定了其发生率。
截至2024年2月，对PubMed和Embase数据库进行了全面检索，以查找关于副舟骨的研究。提取了有关副舟骨患病率的合格数据。本研究严格遵循系统评价和荟萃分析的首选报告项目（PRISMA）指南。
我们的研究共分析了39项研究、11015名患者和36837只足。在患者分析和足部分析中，副舟骨的合并患病率估计值（PPE）分别为17.5%（95%CI：11.5 - 25.7）和12.6%（95%CI：10.1 - 15.5）。50.0%的患者双侧出现副舟骨，在基于性别的分组中分布相似（21.1%的男性和22.0%的女性被确诊有副舟骨）。副舟骨在东亚人群中最为普遍（38.4%），在北美人群中最不普遍（8.0%）。在比较不同成像方式（X线和尸体解剖）时，副舟骨患病率无显著差异。
副舟骨在影像学研究中是常见发现。其患病率取决于研究覆盖的人群，但不受患者性别或用于评估副舟骨的成像方式影响。
