目的：本研究旨在确定基底旁下表面孔隙和骨膜下新骨形成的病因。
方法：总共199名年龄在妊娠36周至3.5岁之间的非成人个体，从英国总共12个考古遗址中，包括铁器时代（n=43），Roman(n=12),和后中世纪(n=145)遗址，还有一个保存完好的巴拉利斯。
方法：将基底分为六段，具有多孔性（微观和宏观）和骨膜下新骨形成记录在下表面的珠光体和非珠光体个体。使用生物学方法开发的古病理学文献中的标准诊断了镰刀。
结果：在所分析的6个区段中，有4个区段没有统计学上的显著差异。在非火山岩和火山岩个体中，年龄与微孔之间存在显着负相关。在珠光体和非珠光体个体之间观察到骨膜下新骨形成的显着差异。
结论：在非成人骨骼遗骸（小于3.5年）的镰刀病宏观评估中，不应考虑基底下部的微孔性。
结论：本研究强调了在过去人群中过度诊断为镰刀病的风险。
结论：1岁以下个体骨骼的生理（正常）和病理（异常）骨骼变化难以区分。
■未来的研究应侧重于对3.5岁以上个体的分析。
OBJECTIVE: This research aims to determine the aetiology of porosity and subperiosteal new bone formation on the inferior surface of the pars basilaris.
METHODS: A total of 199 non-adult individuals aged 36 weeks gestation to 3.5 years, from a total of 12 archaeological sites throughout the UK, including Iron Age (n=43), Roman (n=12), and post-medieval (n=145) sites, with a preserved pars basilaris.
METHODS: The pars basilaris was divided into six segments, with porosity (micro and macro) and subperiosteal new bone formation recorded on the inferior surface in scorbutic and non-scorbutic individuals. Scurvy was diagnosed using criteria from the palaeopathological literature that was developed using a biological approach.
RESULTS: There was no statistically significant difference in microporosity between scorbutic and non-scorbutic individuals in four out of the six segments analysed. There was a significant negative correlation between age and microporosity in non-scorbutic and scorbutic individuals. A significant difference in subperiosteal new bone formation was observed between scorbutic and non-scorbutic individuals.
CONCLUSIONS: Microporosity on the inferior pars basilaris should not be considered among the suite of lesions included in the macroscopic assessment of scurvy in non-adult skeletal remains (less than 3.5 years).
CONCLUSIONS: This study highlights the risk of over diagnosing scurvy in past populations.
CONCLUSIONS: It is difficult to distinguish between physiological (normal) and pathological (abnormal) bone changes in the skeleton of individuals less than one year of age.
UNASSIGNED: Future research should focus on the analysis of individuals over 3.5 years of age.
