Radiograms show the rapid absorption of the new bone both on the surface
and in the marrow, and are of value in establishing the therapeutic
diagnosis.
In certain cases, and particularly when there are destructive changes in
the bone complicated with pyogenic infection, specific remedies have
little effect. In cases of persistent or relapsing gummatous disease
with ulceration of skin, it is often necessary to remove the diseased
soft parts with the sharp spoon and scissors, and to gouge or chisel
away the unhealthy bone, on the same lines as in tuberculous disease.
When hyperostosis and sclerosis of the bone is attended with severe pain
which does not yield to blistering, the periosteum may be incised and
the sclerosed bone perforated with a drill or trephine.
