Background Sexual dimorphism in human bones has mostly been confined to the study of the bony pelvis. However, considerable changes also exist in the other parts of the skeletal system. This study focuses on the differences in the morphometry of male and female adult scaphoids. Aims and objectives We aim to study the morphometry of male and female adult human scaphoids and determine the differences between the same. Materials and methods A total of 100 scaphoids were freshly dissected from both hands of 25 male and 25 female cadavers in Saveetha Medical College, Chennai, India. The soft tissues were loosened using 5% potassium hydroxide (KOH) solution. Further, the soft tissues were removed by meticulous dissection. For the measurements, vernier calipers and threads for circumference measurement were used. Results The morphometric parameters included length, proximal width, width of the middle part (waist), distal width and circumference of the waist, and circumference of the tubercle in scaphoids. Statistical differences were found in most of the parameters. Conclusion A statistically significant difference exists between the morphometric measurements of male and female adult scaphoids, which may prove helpful in the fracture fixation of the scaphoid, as scaphoid fracture has a risk of avascular necrosis.
背景 人类骨骼中的性别二态性大多局限于对骨盆的研究。然而，骨骼系统的其他部位也存在相当大的差异。本研究聚焦于成年男性和女性舟状骨形态测量学的差异。
目的 我们旨在研究成年男性和女性人类舟状骨的形态测量学，并确定两者之间的差异。
材料与方法 从印度钦奈萨维塔医学院的25具男性和25具女性尸体的双手上新鲜解剖出总共100块舟状骨。使用5%氢氧化钾（KOH）溶液松解软组织。进一步通过细致解剖去除软组织。测量时，使用游标卡尺和用于测量周长的线。
结果 形态测量参数包括舟状骨的长度、近端宽度、中部（腰部）宽度、远端宽度和腰部周长、结节周长。大多数参数存在统计学差异。
结论 成年男性和女性舟状骨的形态测量存在统计学显著差异，这可能对舟状骨骨折固定有帮助，因为舟状骨骨折有缺血性坏死的风险。
