The effect of the weight may also be intensified by the prolonged assumption of one position, as in certain callings, by the demands of school life, and the relative immobility incident to advancing years. The effect of the weight is enhanced by eccentric loading, as in bad posture in sitting, writing, and in static cases. Many of the congenital cases are closely associated with a tilted pelvis. The resistance of the spinal mechanism may be diminished by the occurrence of bony softening, as in rickets, osteomalacia; or by atropine changes, as in old age; or by prolonged inactivity from severe illnesses. The effect of paralysis or muscular weakness is obvious.2 Granting, then, that relative insufficiency is the ultimate causation, this may be brought about in various ways, the proximate causes giving rise to different aetiological forms. There are many aetiological forms, and several of them are numerically unimportant, still, as they throw much light on the etiological, problem, we cannot afford to neglect them, even at the risk of appearing somewhat pedantic. We shall therefore deal with a somewhat extended causal classification, bearing in mind always that the great bulk of the cases come under three headings--the idiopathic or constitutional, effects of 1 Orlh.
