    Notizen: Abstract Metacarpal and phalangeal lengths were measured on 1290 hand radiographs of Nigerian children, aged 3–16 years. The radiographs were obtained during a combined cross-sectional and longitudinal study of growth and development. There is a linear increase in tubular bone length with age in both sexes. The girls have higher values for all the bones up to the age of 13 years when the boys overtake them. Comparison of our data with those from North American children shows that the values amongst Nigerian children are higher than White, Black American and Mexican American children. Of particular note is the difference between Black American and Nigerian figures. It is postulated that the decreased metacarpophalangeal lengths in Black Americans compared with Nigerians may be due to ‘gene dilution’.

    Cortical bone mass in Nigerian children: an anthropometric assessment (1994)
    Springer
    Skeletal radiology 23 (1994), S. 49-52 
    Details
    ISSN: 1432-2161

    Notizen: Abstract Cortical bone mass was quantified in 1278 Nigerian children (695 males and 583 females) aged 3–16 years in a prospectively designed cross-sectional and longitudinal study. The total bone width (T) and medullary cavity width (M) were measured at the midshaft of the second metacarpal bone using a direct reading caliper. From the above measurements the cortical width (C), cortical area (CA), and percent cortical area (PCA) were calculated using the method of Garn et al. [6] and showed a progressive increase of T, C, CA and PCA, reaching a plateau at 15 years. At all ages, the values for both T and M are higher in males than in females. On the other hand, and contrary to established normal values amongst both white and black Americans, between the ages of 9 and 15 the female values for C are higher than those for males. This difference is greatest at the age of 12 years (p〈0.001). The implication of this finding may be that during these years, African male children do not compensate for the increased endosteal resorption with a greater total cortical width (T), since the medullary width in females remains relatively constant over the years.
