_The induction of hyperaemia_ is often helpful, the rubber bandage or the
hot-air chamber being employed for an hour or so morning and evening.
_Injection of Iodoform._--This is carried out on the same lines as have
been described for tuberculous abscess. After the fluid contents of the
joint are withdrawn, the iodoform is injected; and this may require to
be repeated in a month or six weeks.
After the injection of iodoform there is usually considerable reaction,
attended with fever (101 F.), headache, and malaise, and considerable
pain and swelling of the joint. In some cases there is sickness, and
there may be blood pigment in the urine. The severity of these phenomena
diminishes with each subsequent injection.
