The effects of age and occupation on cortical bone in a group of adult males from the 18th-19th century AD skeletal collection from Christ Church Spitalfields, London, were investigated. Cortical bone was monitored using metacarpal radiogrammetry. Individual age at death was known exactly from coffin plates. Occupation for individuals was known from historical sources. Results showed that continued periosteal apposition was evident throughout adult life, but from middle age onwards this was outstripped by about 2:1 by endosteal resorption, so that there was net thinning of cortical bone. The rate of cortical thinning resembled that seen in modern European males. Cross-sectional properties, as measured by second moments of area, bore no relationship to occupation. The results may suggest that, firstly, patterns of loss of cortical bone have remained unchanged in males for at least two centuries in Britain, and secondly, that biomechanical analyses of metacarpal cortical bone may be rather insensitive indicators of intensity of manual activity.
对一组来自公元18至19世纪伦敦基督教堂斯皮塔菲尔德骨骼收藏的成年男性皮质骨,研究了年龄和职业的影响。使用掌骨X线测量法监测皮质骨。从棺材板上能准确得知个体的死亡年龄。个体职业可从历史资料中获悉。结果显示,成年期全程都有明显的骨膜增生,但从中年起,这种增生被约2:1的骨内膜吸收超过,导致皮质骨净变薄。皮质骨变薄速率与现代欧洲男性相似。以面积二次矩测量的横截面特性与职业无关。结果可能表明,首先,在英国男性中,皮质骨流失模式至少在两个世纪以来一直未变;其次,掌骨皮质骨的生物力学分析可能是体力活动强度相当不敏感的指标。
