    Humeral cortical thickness in female Bantu — Its relationship to the incidence of femoral neck fracture (1982)

    Notes: Abstract Measurements of the humeral cortical thickness demonstrate that generalised osteoporosis in female Bantu commences in the fifth decade and gradually increases until, in the ninth decade, all subjects are osteoporotic. The combined cortical thickness (CCT) of the humerus in young adults is very similar to that found previously in a white London population and the loss of cortex with age is very similar. It is concluded that the known low incidence of femoral neck fracture in Bantu is not due to a lower incidence of generalised osteoporosis but to environmental factors. The chief environmental factor postulated is the greater amount of physical work performed by the Bantu. A more careful mode of walking is suggested as a subsidiary cause.

    Radiogrammetry of the metacarpal: A critical reappraisal (1983)
    Springer
    Skeletal radiology 10 (1983), S. 5-9 
    Details
    ISSN: 1432-2161
    Keywords: Metacarpal ; Cortical thickness ; Osteoporosis

    Topics: Medicine
    Notes: Abstract The precise estimation of osteoporosis is hampered by the lack of a generally accepted method of evaluation. Measurement of the combined cortical thickness (CCT) of the centre point of the second metacarpal has been widely used for this purpose, but the wide normal variation found in population studies has reduced its value in the diagnosis of this condition in the individual. The factors leading to this normal variability are discussed and the three centre metacarpals are compared with each other. It is concluded that simple CCT measurement is preferable to any of the indices so far devised, but that a single measurement of a given metacarpal is too imprecise to be of real value. If a single metacarpal is to be chosen, three measurements of the third metacarpal gives a coefficient of variation lower than those of the second or fourth, and an average of nine measurements of the three centre metacarpals produces a further useful reduction in variability.

    The assimilated os sustentaculi (1986)
    Springer
    Skeletal radiology 15 (1986), S. 455-457 
    Details
    ISSN: 1432-2161
    Keywords: Accessory bones ; Skeletal anomaly ; Talus ; Calcaneus
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The assimilated os sustentaculi is a projection of bone from the medial aspect of the sustentaculum tali which is surmounted by a similar projection from the medial tubercle of the talus. The accessory joint so formed may develop secondary osteoarthritis changes. This congenital anomaly is very rate. The present report is of 2 additional cases.

    Frontal lobe calcification in hypoparathyroid states (1983)

    Description / Table of Contents: Zusammenfassung Verkalkungen in den Stammganglien sind bei Hypoparathyreoidismus häufig, Verkalkungen der Hirnrinde jedoch selten. Von den bisher beschriebenen sechs Fällen wurden fünf bei Patienten mit idiopathischem Hypoparathyreoidismus und nur einer bei einem Patienten mit Pseudohypoparathyreoidismus beobachtet. In der vorliegenden Arbeit wird der zweite Fall von Pseudohypoparathyreoidismus mit Hirnrindenverkalkungen beschrieben. Es wird auf die vorwiegend frontale Lokalisation der Rindenverkalkungen hingewiesen.
    Notes: Summary Basal ganglion calcification is common in hypoparathyroid states. However, cerebral cortical calcification is rarely seen. Of the six cases previously recorded, five were in patients with idiopathic hypoparathyroidism and only one in a patient with pseudohypoparathyroidism. The present report is of a second case of pseudohypoparathyroidism with cerebral cortical calcification. It is stressed that cortical calcification occurs predominantly in the frontal lobes.
