The accessory navicular bone (ANB) is one of the most common accessory bones in the foot. Certain pathologies, such as posterior tibial tendon insufficiency are associated with ANB, and should be differentiated from midfoot and hindfoot fractures such as navicular tuberosity avulsion fractures. There are few studies addressing the prevalence and types of ANB in Saudi Arabia.
Determine the prevalence and morphological variations of ANB and its relation with age and sex in patients visiting foot and ankle clinics.
Medical record review SETTING: Orthopedic foot and ankle clinic at a university hospital.
The presence of ANB was retrospectively analyzed in radiographs from patients who presented to the orthopedic foot and ankle at our university hospital from February 2010 to December 2020. The patients were stratified according to sex, age, and diagnosis. For each ANB, recorded information included site, size, classification, subtypes, and symptomatology. Purposive sampling was used to select the patients for the study (non-probability sampling).
Prevalence of ANB in patients attending a foot and ankle clinic.
117 patients and 194 feet.
ANB was analyzed in 1006 radiographs from 503 patients. ANB was detected in 117 (23.3%) patients and 194 (19.3%) feet Prevalence was significantly higher in females (67.5%) than in males (32.5%) (Z=5.359, <.001). The ages ranged from 19 to 86 years, with a mean age of 48.26 (14.5) years. The most common site was bilateral (77 patients, 65.8 %). Type I was the most common type, with a prevalence of 42.1%. There were no significant differences in types in relation to sex, but all types and subtypes differed significantly from each other.
ANB was common among patients presenting to the foot and ankle clinic, with an overall prevalence of 23.3%. It should be considered among the differential diagnosis in chronic foot pain, and should be differentiated from midfoot and hindfoot fractures. Further studies with a larger, randomized sample are needed, for more accuracy and to confirm the reported results.
Retrospective chart review, non-probability sampling, and use of plain radiographs.
None.
副舟骨是足部最常见的副骨之一。某些疾病，如胫骨后肌腱功能不全，与副舟骨有关，应与中足和后足骨折（如舟骨结节撕脱骨折）相鉴别。在沙特阿拉伯，很少有研究涉及副舟骨的患病率和类型。
确定在我们大学医院足踝诊所就诊的患者中，副舟骨的患病率、形态变异及其与年龄和性别的关系。
病历回顾
大学附属医院骨科足踝诊所
对 2010 年 2 月至 2020 年 12 月期间在我院骨科足踝诊所就诊的患者的 X 线片进行回顾性分析，观察副舟骨的存在情况。患者按性别、年龄和诊断进行分层。对每一块副舟骨，记录的信息包括部位、大小、分类、亚型和症状。采用目的抽样法选择患者进行研究（非概率抽样）。
在足踝诊所就诊的患者中副舟骨的患病率。
117 例患者，194 只足。
对 503 例患者的 1006 张 X 线片进行了副舟骨分析。117 例（23.3%）患者和 194 只（19.3%）足发现了副舟骨。女性（67.5%）的患病率明显高于男性（32.5%）（Z=5.359，<.001）。年龄范围为 19 至 86 岁，平均年龄为 48.26（14.5）岁。最常见的部位是双侧（77 例，65.8%）。I 型最常见，患病率为 42.1%。性别与类型之间无显著性差异，但各类型和亚型之间存在显著性差异。
在足踝诊所就诊的患者中，副舟骨很常见，总体患病率为 23.3%。在慢性足部疼痛的鉴别诊断中应考虑副舟骨，并应与中足和后足骨折相鉴别。需要进一步进行更大样本量、随机抽样的研究，以提高准确性并证实报告结果。
回顾性病历回顾、非概率抽样和使用普通 X 线片。
无。
