As to joints, there are certain special points to be noticed as, if the controlling sinews have been divided, weakness of the part concerned follows. If this is in doubt, and the wound has been made by a sharp weapon, a transverse wound is the more favourable; if by a blunt and heavy weapon, the shape of the wound makes no difference. But it is to be observed whether pus is being formed above the joint or beneath. If it is produced underneath, and thick and white discharge continues for some time, it is probable that a sinew has been cut, and the more so the greater the pains and inflammation, and the earlier these occur. But even though no sinew is divided, yet, if a hard swelling persists for a long while round about, the wound will last a long time and even after healing a swelling will persists; and in future that limb will be bent or stretched out slowly. There is, however, more delay in extending a limb which has been kept bent while treated, than in bending a limb which has been kept straight. Also there should be a definite rule as to position for a limb which has been wounded. If the wound is seem to be agglutinated, the limb is kept raised; it must not be bent either way if there is still inflammation; if pus is already being discharged it should be hanging down. The best medicament too is rest; movement and walking before healing are adverse. The danger, however, from movement is less for wounds of the head and arms than for the lower limbs. Walking about is least of all suited to an injured thigh or leg or foot. The patient's room should be kept warm. Bathing, too, while the wound is not yet clean, is one of the worst things to do; for this makes the wound both wet and dirty, and then there is a tendency for gangrene to occur. It is advantageous to apply light rubbing, but in those parts which are rather far away from the wound.
