Evidence for X‐linkage of tibial length and body length
Sister‐sister, brother‐brother and sister‐brother similarities in both tibial length and stature from one month through 10 years are in accord with the hypothesis of partial X‐linkage, they reject the hypothesis of selective inactivation of an X chromosome, and they indicate that the complex that is body length is suited to simplistic analysis
Apparent influence of the X chromosome on timing of 73 ossification centers
Among 73 postnatal ossification centers, sister‐sister (SS) corretions involving age at appearance tend to exceed brother‐brother (BB) and sister‐brother (SB) correlations by an average of 0.16. This excess of SS over BB and SB ossification timing similarity is not a function of type of center, limb or location, and is in accordance with the hypothesis of partial X‐linkage. It is estimated that the larger proportion of genetically determined vari…
Further evidence for continuing bone expansion
Additional and extended data on 2726 subjects from Costa Rica, Honduras, Nicaragua and Panama provide confirming evidence for continuing bone expansion of the second metacarpal at midshaft. As shown in 4924 subjects from eight populations, subperiosteal apposition is more rapid in the female than in the male, and accounts for a net increase of 10% in cross‐sectional area from age 25 to age 85. Unlike endosteal resorption, which is precipitous in …
Population frequencies and altered remodeling mechanisms in normal medullary stenosis
As shown in 2065 women aged 18 to 45 years from seven countries of Central and North America, the population frequency of normal medullary stenosis ranges from under 2% to nearly 7%. In this condition, endosteal apposition may begin in infancy and continue through the fourth decade with a compensatory reduction in the rate of subperiosteal apposition, leading to an approximately normal cortical cross‐sectional area contained in a smaller subperio…
Continuing bone growth throughout life
Cross‐sectional data on 2799 subjects from five different populations and longitudinal data on 113 older adults indicate continuing adult bone growth in the second metacarpal. Similar 6‐decade increases in the size of the cranium confirm continuing bone growth as a general phenomenon not necesarily related to weightbearing or flexion stress and representing an increase of approximately 10% in skeletal volume concomitant with the major age‐associa…
Ossification communalities of the hand and other body parts
Correlating the age at appearance of 71 postnatal ossification centers (OC's) with every other OC, 4,970 correlations in all, then grouping correlations by body part, the hand does not exhibit usefully higher communality (mean r ) than the foot, shoulder, hip, elbow or knee. While low communality round bones and ossification sequence polymorphisms together account for the fact that no one body part adequately represents the entire skeleton, it is…
Ossification sequence polymorphism and sexual dimorphism in skeletal development
Ossification sequence polymorphism and sexual dimorphism are prevalent in the postnatal skeletal development of the hand, foot, elbow, knee, shoulder and pelvis. For some ossification polymorphisms the sex‐discriminatory efficiency is greater than 70%. Current evidence, including population comparisons, and children with kwashiorkor and marasmus, favors a genetical explanation for common sequence polymorphisms. However, ossification sequence poly…
Communalities” in the ossification timing of the growing foot
After investigating communality of ossification timing (mean intercorrelation during growth) for 24 postnatal ossification centers of the foot, it is obvious that some bony nuclei have maximum predictive value and others provide little information about the ossification status of the growing foot. Employing the ten centers of highest communality in both sexes (primarily proximal and metatarsal centers) and excluding the cuboid, lateral cuneiform …
Developmental communalities of homologous and non‐homologous body joints
Reducing 4970 center‐ and sex‐specific correlations for age at appearance of postnatal ossification centers to 15 mean values of r representing homologous and non‐hmologous inter‐limb and intra‐limb joint segment communalities, it was shown that homologous joint segments in different limbs (hand‐foot, elbow‐knee, shoulder‐hip) showed systematically higher developmental communality than intra‐limb non‐homologous joints, and these in turn exceeded …
