Sesamoid bones show considerable variations in their occurrence among various ethnicities. This study aims to evaluate the prevalence and distribution patterns of the sesamoid bones of the hands among Omani patients who were referred for radiological investigations. The influence of gender and different age groups on the occurrence of sesamoid bones of the hand was determined using the Chi-square test. Spearman's rank correlation was used to determine the coexistence of sesamoid bones at the metacarpophalangeal joints. A total of 541 hand radiographs were reviewed. A high prevalence of sesamoid bones at the fifth metacarpophalangeal joint and the interphalangeal joint of the thumb was noted with a frequency of 64% and 49.7%, respectively. There were ten different patterns of sesamoid bones detected, the most common of which was the presence of sesamoid bones at the first and fifth metacarpophalangeal joints found in 32.9% of the radiographs. A statistically significant gender difference was observed at the interphalangeal joint of the thumb (p = 0.025) and fifth metacarpophalangeal joint (p = 0.027) with a female dominance. A significant association between the age and prevalence of sesamoid bones was noted at the fifth metacarpophalangeal joint (p = 0.03). The prevalence of the sesamoid bones of the hand in Omani subjects seems to differ from other Middle Eastern populations, particularly at the fifth metacarpophalangeal joint and the interphalangeal joint of the thumb. In the meantime, the baseline data of our study can be helpful while treating the patients complaining of hand discomfort or pain.
籽骨在不同种族中的出现存在很大差异。本研究旨在评估手部籽骨在手部影像学检查中奥曼患者的发生率和分布模式。使用卡方检验确定性别和不同年龄组对手部籽骨发生的影响。使用 Spearman 秩相关来确定掌指关节处籽骨的共存情况。共回顾了 541 张手部 X 光片。第五掌指关节和拇指指间关节的籽骨发生率很高，分别为 64%和 49.7%。共发现 10 种不同类型的籽骨，最常见的是第一和第五掌指关节存在籽骨，在 32.9%的 X 光片中发现。拇指指间关节（p=0.025）和第五掌指关节（p=0.027）的性别差异具有统计学意义，女性更为多见。在第五掌指关节（p=0.03）观察到年龄与籽骨发生率之间存在显著关联。奥曼受试者手部籽骨的发生率似乎与其他中东人群不同，尤其是在第五掌指关节和拇指指间关节。同时，我们研究的基线数据在手部不适或疼痛的患者的治疗中可能会有所帮助。
