The elbow, when luxated, induces the most serious consequences, fevers, pain, nausea, vomiting of pure bile; and this especially in dislocations backward, from pressure on the nerve which occasions numbness; next to it is dislocation forward. The treatment is the same. The reduction of dislocation backward is by extension and adaptation: the symptom of this variety, loss of the power of extension; of dislocation forward, loss of the power of flexion. In it a hard ball is to be placed in the bend of the elbow, and the fore-arm is to be bent over this while sudden extension is made.

Diastasis of the bones may be recognized by examining the part where the vein which runs along the arm divides.

In these cases callus is speedily formed. In congenital dislocations, the bones below the seat of the injury are shorter than natural; in this case, the greatest shortening is in the nearest, namely, those of the fore-arm; second, those of the hand; third, those of the fingers. The arm and shoulders are stronger, owing to the nourishment which they receive, and the other arm, from the additional work it has to perform, is still more strong. The wasting of the flesh, if the dislocation was outward, is on the inside; or if otherwise, on the side opposite the dislocation.
