Dislocations at the elbow give rise to the most serious consequences, such as fevers, pain, nausea, vomitings of pure bile, and more especially when the humerus is displaced backward from pressure on the nerve, which occasions numbness; next to it is the dislocation forward; the treatment is the same; reduction in 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, and in this case reduction is to be accomplished by placing a hard ball (in the bend of the elbow), and bending the fore-arm about it, along with sudden extension.

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

In those cases callus is quickly formed. In congenital dislocations the bones below the seat of the injury are shorter than natural, and, mostly, those nearest to the place; namely, the bones of the fore-arm, next those of the hand; and, third, those of the fingers. The arm and shoulder are stronger, owing to the nourishment which they receive, and the other arm, from the additional work which it has to perform, is still more strong. Wasting of the flesh takes place on the inside if the dislocation be on the outside; or otherwise, on the side opposite the dislocation.
