[p. 284]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
In dislocation at the elbow, whether outward or inward, extension
is to be made with the fore-arm at right angles to the arm; the arm
is to be suspended by a shawl passed through the armpit, and a weight
is to be attached to the extremity of the elbow; or force is to be
applied with the hands. The articular extremity being properly raised,
the parts are to be adjusted with the palms of the hands, as in dislocations
of the hands. It is to be bandaged, suspended in a sling, and placed,
while in this attitude.
Dislocations backward are to be rectified with the palms of the hands
along with sudden extension. These two acts are to be performed together,
as in other cases of the kind. In dislocation forward, the arm is
to bend around a ball of cloth, of proper size, and at the same time
If the displacement be on the other side both these operations are
to be performed in effecting the adjustment of the arm. With regard
to the treatment,-the position and the bandaging are the same as in
the other cases. For all these cases may be reduced by ordinary distention.
With regard to the modes of reduction, some act upon the
