33. When the fracture exists at the superior part of the radius, it is essential, after the removal of the apparatus, to make the limb very frequently perform all its natural motions. In such a case, indeed, the parts sometimes swell, become stiff, and an anchylosis of the fore-arm may be the consequence, as Ambrose Pare observes, in his book on fractures, where he says he has seen many accidents of this kind. Galen has remarked the same thing before him. The following case reported by Jeo. Dol**, confirms the truth of it.

Case II. Jane Rene was received into the Hotel-Dieu, in consequence of a fracture of the upper extremity of the radius, produced by a fall on that part, for which she was subjected to the treatment already described (31). The apparatus being removed at the expiration of twenty-five days, the consolidation was perceived to be complete. The motions of pronation and supination were impracticable; those of flexion and extension very much impeded. The patient was now ordered to have the fore-arm moved daily, in these several directions, for the space of an hour, and this space was even increased morning and evening, notwithstanding the pains which, at first, accompanied the exercise. On the eighth day pronation and supination could already be performed in a small degree; they became more and more free, in proportion as the exercise of the limb was longer continued; finally, on the twenty-second day from the removal of the apparatus, the patient was conducted, according to custom, to the amphitheatre, where all the pupils witnessed the perfect freedom of the motions.

Case III. A few days after this, a man, who had left the Hotel-Dieu about eight months before, while under treatment for a similar fracture, returned, to be the subject of a public consultation in consequence of a different disease.

Desault, on interrogating him, learnt from him that the treatment for the fracture had been continued at his own house (31), but that, when the apparatus was removed, no motion had been impressed on the limb, and that the surgeon had even kept it in a sling. The fore-arm was then examined; it was half bent, constantly in a state of pronation, and could not, by any force, be brought into a state of supination. The motions of flexion and extension, were so limited as to be scarcely sufficient for the common wants of the patient, who, under proper treatment, might have been cured like the preceding one, as Desault remarked to his pupils at the time.

34. The patient who was the subject of this second case, was sent to the mineral springs, but derived no benefit from the use of the waters. If this were a proper occasion, I could mention many instances where this remedy, so highly spoken of by many physicians of the present time, has had no effect, except to deprive the patient of more efficacious means, by making him lose that time, during which exercise frequently repeated, would have effected a cure, but which, coming too late, could be of no avail.

FRACTURE OF THE ULNA.

§ X.

OF THE CAUSES AND THE SIGNS.

35. The ulna, less frequently broken, in general, than the radius, scarcely ever suffers alone from falls on the wrist or hand. Most commonly its fracture is direct, and occurs, in particular, in cases where a person in falling, extends the fore-arm for the purpose of supporting himself, and strikes its internal part against some resisting body.
