128. Permanent extension, made in the manner already mentioned (60 ... 63), fulfils the two first indications; while two lateral splints, and the bandage of strips fulfils the third. Desault, therefore, applied to this particular case his apparatus for permanent extension, modified only in such a way, that, instead of terminating at the knee, the bandage of strips was continued to a distance down the leg, in order that its action might be the more efficacious. For, it is well known, that it is at its middle part that the firmness and retentive power of a bandage are greatest, because the casts of the roller at the upper and lower ends, serve to secure those in the middle. The upper splint being altogether useless, was not employed. 129. If the superior fracture be transverse, the condyls, as I have already said, meet with resistance against the body of the bone, while they, on the other hand, support it in such a manner, as to prevent it from descending, though pushed by the weight of the body along the inclined plain made by the pressure of the nates. Here, then, permanent extension is generally useless, and all that is necessary is, to retain the condyls and prevent their separation by means of lateral pressure. The same apparatus may still be employed, provided the two rollers for extension be laid aside. 130. If a wound in the soft parts accompany the fracture, whether it be produced by the same cause, or by the subsequent passage of the fragments through the integuments, and whether it communicate with the articulation or not, it is necessary, as soon as suppuration has taken place, to renew the dressings every day or every other day, taking care, in the mean time, to supply, by the hands of an assistant, the want of extension by means of the apparatus. The following case, extracted from the Journal, exhibits a specimen of the treatment that ought to be adopted in similar cases. CASE XI. Claudius Legrange, aged thirty-one, and of a sound constitution, was wounded by the kick of a horse, on the internal condyl of the left os femoris. The violence of the pain obliged him to throw himself on a heap of straw, that lay at a little distance, and which he reached by hopping on his right foot. The pains were augmented by this, for at each step, the thigh being alternately bent or extended at the injured part, was moved sometimes backward and sometimes forward. The patient was brought to the Hotel-Dieu, a few hours after the accident. The signs already specified (121 and 122) announced to Desault, a longitudinal fracture separating the two condyls, and terminated above by another fracture of the body of the bone, which descended obliquely from about five inches above the external condyl, to within two inches of the internal one.
