If the fracture exist at the end of the clavicle next to the humerus, the difficulty of their being displaced renders the application of the bandage less necessary. Prudence, however, demands that it be not altogether neglected. § VIII. OF THE TREATMENT DURING THE FORMATION OF THE CALLUS. The regimen to be pursued during the reunion of the clavicle, varies according to circumstances. It is impracticable to lay down general rules, applicable to all affections of this kind. Here, however, much more than in other cases, if the division of the bone be simple, and no unfortunate accident occur, it is always unnecessary to restrain the patient from his usual course of life, beyond the second or third day. But, though internal means are for the most part omitted in the treatment, the apparatus is a subject on which too much attention cannot be bestowed. With whatever degree of exactness it may be at first applied, it will soon become loose, and oppose a diminished resistance to the weight of the shoulder, and the action of the muscles. Hence, unless it be frequently examined, the fragments will be displaced. The following case furnishes a detail of the treatment subsequent to the reduction, to which, in ordinary cases, Desault had recourse. CASE III. Mary Adel, aged thirty, as she was crossing a path covered with ice, in the severe winter of 1788, fell on the point of her left shoulder, and fractured the clavicle about the middle. Being brought to the Hotel-Dieu a few hours after the accident, she was dressed in the manner just described, and, as the fracture was simple, it was judged sufficient to make a slight diminution in the quantity of her aliment, during the two or three first days. The dressing was moistened every morning, with vegeto-mineral water, at the place corresponding to the fracture. On the fourth day the piece of linen that surrounded the bandage was removed, for the purpose of examining the state of the parts. Every thing was found in its proper situation, and the covering was replaced till the seventh day, when the rollers appeared to be somewhat relaxed. The apparatus was taken off, and reapplied as at first, the compresses being carefully moistened with vegeto-mineral water, at the part lying over the fracture. After the third day the patient was permitted to return to her usual regimen. The third roller being a little deranged on the tenth day, it was taken off, and reapplied as at first, together with the sling. The fragments were examined and found in perfect contact. The patient was up during the whole day, walked about the house, and experienced no other inconvenience than that of not being able to use the left arm. On the thirteenth day, the bandage was again reapplied, and allowed to remain till the sixteenth, when the patient having disturbed it, it was once more changed. At this period, the fragments, already firmly united, exhibited scarcely a vestige of the division they had sustained.
