Not illustrated. 1882 Excerpt: ... by the fact that the in-knee commonly called statical (as distinct from rachitic), and which we prefer to call atonic, originates when the growth is most rapid, not only in early infancy and childhood at the age and during the years in which rickets invariably begins and ends (distortion perhaps remaining unless counteracted by art), but may originate also between the ages of five and twelve, and especially often during the second fast-growing period which precedes puberty (age twelve to sixteen or seventeen), when rachitis does not originate. We believe that there is not a single fact on record to show that any symptom or sign of rickets affecting the bones (softening and subsequent eburnation) or other parts of the frame was ever observed to originate within those years. We would enquire, Who has ever seen a case of rickets, such as figs. 32, 33, and 34, originate at any other period than early childhood? There have been plenty of in-knees without bone softening and curvature, such as fig. 5, seen to originate after childhood, but these we have shown are non-rachitic. We are aware that several most able men believe they have seen rickets originate during adolescence, because they have seen statical non-rachitic knock-knee produced at that period, but they have assuredly been mistaken. We consider that no pathologist will deny that unequivocal rachitis exhibits distinct stages, that these stages run a definite course as to time and as to the nature of the bone and constitutional changes; and the osseous system, which has once traversed the ordinary rachitic stages, has never been known to traverse these stages a second time, differing in this respect from somewhat analogous bone changes which occur in another disorder, scorbutus. Another fact, which confi...
