Under this head we shall first speak of fracture of bones, which we define to be a sudden solution of continuity in a bone, generally produced by external violence.

This, however, is not sufficient. The surgeon must investigate more minutely. He must take into consideration all those circumstances which may produce a tendency to fracture. We find these existing very differently in different individuals. So much is this the case, that in some persons muscular contraction alone is sufficient to produce a fracture. In speaking then of the causes of fracture, we divide them into two classes. First, the predisposing, and secondly, those which we denominate exciting. What then are the predisposing causes? They are numerous and diversified. And here I would remark, that at all periods of life we are liable to fracture. Even the foetus in utero is exposed to this accident. As regards the cause of intra-uterine fractures, there is a great difference of opinion. Some suppose the contraction of the wound to be the cause. This, however, is not probable. Others suppose that by the carelessness and rude handling of the accoucheur at birth, these fractures are produ...
