本研究调查了史前绳纹狩猎采集者和现代日本人之间腓骨骨干弯曲的差异。分析中包括40名绳文晚期/末期（约4300-2500年BP）和75名现代日本人的115具骨骼遗骸。根据从额状面和矢状面拍摄的数字照片，在腓骨长度的20-80%之间的每5%骨干区域测量前后和内外侧骨干弯曲程度。比较两个群体和性别之间的腓骨干曲率，并证实腓骨干曲率与骨干横截面形态和身体大小变量之间的相关性。结果表明，绳纹和现代日本人口之间的前后骨干曲率的显着差异，并指出一个显着弯曲的前方向绳纹男性和女性，与现代日本男性和女性相比。相反，在中外侧骨干弯曲方面，观察到的人群差异很小。腓骨干的弯曲度与体型变量的相关性较小。此外，前后向骨干曲率与骨干稳健性相关，与骨干形状相关性较低。前后弯曲和骨干横截面形态之间的关系，习惯性活动的指标，得到证实。这表明腓骨弯曲可能也受到日常活动的机械负荷的影响。
This study investigated differences in the fibular diaphyseal curvature between prehistoric Jomon hunter–gatherers and modern Japanese people. A total of 115 skeletal remains of 40 individuals from the Late/Final Jomon period (approximately 4300–2500 years BP) and 75 modern Japanese individuals were included in the analysis. The degree of anteroposterior and mediolateral diaphyseal curvature was measured based on digital photographs taken from the frontal and sagittal planes at every 5% diaphyseal region between the range of 20–80% of the fibular length. Fibular diaphyseal curvature was compared between both populations and sexes, and the correlation between fibular diaphyseal curvature with diaphyseal cross-sectional morphology and body size variables were confirmed. The results showed significant differences in the anteroposterior diaphyseal curvature between the Jomon and modern Japanese populations, and a significantly curved anterior direction was noted for Jomon males and females, compared with modern Japanese males and females. On the contrary, little populational difference was noted in terms of mediolateral diaphyseal curvature. The curvature of the fibular diaphysis showed less correlation with body size variables. Moreover, anteroposterior diaphyseal curvatures were correlated with diaphyseal robustness and had low correlation with diaphyseal shape. A relationship between anteroposterior curvature and diaphyseal cross-sectional morphology, an indicator of habitual activity, was confirmed. This suggests that the fibular curvature is possibly influenced by mechanical loading from daily activities as well.
